NAME Net::Twitter - A perl interface to the Twitter API VERSION This document describes Net::Twitter version 3.11010 SYNOPSIS use Net::Twitter; use Scalar::Util 'blessed'; my $nt = Net::Twitter->new( traits => [qw/API::REST/], username => $user, password => $password ); my $result = $nt->update('Hello, world!'); eval { my $statuses = $nt->friends_timeline({ since_id => $high_water, count => 100 }); for my $status ( @$statuses ) { print "$status->{created_at} <$status->{user}{screen_name}> $status->{text}\n"; } }; if ( my $err = $@ ) { die $@ unless blessed $err && $err->isa('Net::Twitter::Error'); warn "HTTP Response Code: ", $err->code, "\n", "HTTP Message......: ", $err->message, "\n", "Twitter error.....: ", $err->error, "\n"; } DESCRIPTION This module provides a perl interface to the Twitter APIs. See for a full description of the Twitter APIs. OMG! THE MOOSE! Net::Twitter is Moose based. Moose provides some advantages, including the ability for the maintainer of this module to respond quickly to Twitter API changes. See Net::Twitter::Lite if you need an alternative without Moose and its dependencies. Net::Twitter::Lite's API method definitions and documentation are generated from Net::Twitter. It is a related module, but does not depend on Net::Twitter or Moose for installation. RETURN VALUES Net::Twitter decodes the data structures returned by the Twitter API into native perl data structures (HASH references and ARRAY references). The full layout of those data structures are not documented, here. They change often, usually with the addition of new elements, and documenting all of those changes would be a significant challenge. Instead, rely on the online Twitter API documentation and inspection of the returned data. The Twitter API online documentation is located at . To inspect the data, use Data::Dumper or similar module of your choice. Here's a simple example using Data::Dumper: use Data::Dumper; my $r = $nt->search($search_term); print Dumper $r; For more information on perl data structures, see perlreftut, perldsc, and perllol. METHODS AND ARGUMENTS new This constructs a "Net::Twitter" object. It takes several named parameters, all of them optional: traits An ARRAY ref of traits used to control which APIs the constructed "Net::Twitter" object will support and how it handles errors. Possible values are: API::REST Provides support for the Twitter REST API methods. API::Search Provides support for the Twitter Search API methods. API::TwitterVision Provides support for the TwitterVision API. See . WrapError "Net::Twitter" normally throws exceptions on error. When this trait is included, "Net::Twitter" returns undef when a method fails and makes the error available through method "get_error". This is the way all errors were handled in Net::Twitter versions prior to version 3.00. OAuth The "OAuth" trait provides OAuth authentication rather than the default Basic Authentication for Twitter API method calls. See the "Authentication" section and Net::Twitter::Role::OAuth for full documentation. InflateObjects When this optional trait is included, Net::Twitter inflates HASH refs returned by Twitter into objects with read accessors for each element. In addition, it inflates dates to DateTime objects and URLs to URI objects. Objects that include a "created_at" attribute also have a "relative_created_at" method. For example, with "InflateObjects" applied, the method returns an array of status objects: $r = $nt->friends_timeline; for my $status ( @$r ) { $r->user->screen_name; # same as $r->{user}{screen_name} # $created_at is a DateTime; $age is a DateTime::Duration my $age = DateTime->now - $r->created_at; # print an age in a similar style to the Twitter web site, e.g.: # less than a minute ago # about a minute ago # 6 minutes ago # 1 day ago # etc. print $r->relative_created_at; RateLimit The "RateLimit" trait adds utility methods that return information about the current rate limit status. See Net::Twitter::Role::RateLimit for details. Legacy This trait provides backwards compatibility to "Net::Twitter" versions prior to 3.00. It implies the traits "API::REST", "API::Search", "API::TwitterVision", and "API::WrapError". It also provides additional functionality to ensure consistent behavior for applications written for use with legacy versions of "Net::Twitter". In the current version, this trait is automatically included if the "traits" option is not specified. This ensures backwards compatibility for existing applications using "Net::Twitter" versions prior to 3.00. See section "LEGACY COMPATIBILITY" for more details. Some examples of using the "traits" parameter in "new": # provide support for *only* the REST API; throw exceptions on error $nt = Net::Twitter->new(traits => ['API::REST']); # provide support for both the REST and Search APIs; wrap errors $nt = Net::Twitter->new(traits => [qw/API::REST API::Search WrapError/]); # ensure full legacy support $nt = Net::Twitter->new(traits => ['Legacy']); # currently, these 2 calls to new are equivalent: $nt = Net::Twitter->new(); $nt = Net::Twitter->new(traits => ['Legacy']); legacy A boolean. If set to 0, "new" constructs a "Net::Twitter" object implementing the REST API and throws exceptions on API method errors. Net::Twitter->new(legacy => 0); is a shortcut for: Net::Twitter->new(traits => ['API::REST']); If set to 1, "new" constructs a "Net::Twitter" object with the "Legacy" trait. Net::Twitter->new(legacy => 1); is a shortcut for: Net::Twitter->new(traits => ['Legacy']); username This is the screen name or email used to authenticate with Twitter. password This is the password used to authenticate with Twitter. clientname The value for the "X-Twitter-Client-Name" HTTP header. It defaults to "Perl Net::Twitter". clientver The value for the "X-Twitter-Client-Version" HTTP header. It defaults to current version of the "Net::Twitter" module. clienturl The value for the "X-Twitter-Client-URL" HTTP header. It defaults to the search.cpan.org page for the "Net::Twitter" distribution. useragent_class The "LWP::UserAgent" compatible class used internally by "Net::Twitter". It defaults to "LWP::UserAgent". For POE based applications, consider using "LWP::UserAgent::POE". useragent_args An HASH ref of arguments to pass to constructor of the class specified with "useragent_class", above. It defaults to {} (an empty HASH ref). useragent The value for "User-Agent" HTTP header. It defaults to "Net::Twitter/$VERSION (Perl)", where $VERSION is the current version of "Net::Twitter". source The value used in the "source" parameter of API method calls. It is currently only used in the "update" method in the REST API. It defaults to "twitterpm". This results in the text "from Net::Twitter" rather than "from web" for status messages posted from "Net::Twitter" when displayed via the Twitter web interface. Twitter is no longer registering source parameters. New applications should implement OAuth and register via . Only use the "source" parameter if you have an existing, registered source parameter from Twitter. apiurl The URL for the Twitter API. This defaults to "http://api.twitter.com/1". This option is available when the "API::REST" trait is included. apihost DEPRECATED - Setting the "apiurl" is sufficient. apirealm A string containing the Twitter API realm used for Basic Authentication. It defaults to "Twitter API". This option is available when the "API::REST" trait is included. identica If set to 1, "Net::Twitter" overrides the defaults for "apiurl", "apihost", and "apirealm" to "http://identi.ca/api", "identi.ca:80", and "Laconica API" respectively. It defaults to 0. This option is available when the "API::REST" trait is included. consumer_key A string containing the OAuth consumer key provided by Twitter when an application is registered. This option is available when the "OAuth" trait is included. consumer_secret A string containing the OAuth consumer secret. This option is available when the "OAuth" trait is included. ssl If set to 1, an SSL connection will be used for all API calls. Defaults to 0. netrc (Optional) Sets the *machine* key to look up in ".netrc" to obtain credentials. If set to 1, Net::Twitter will use the value of the "netrc_machine" option (below). # in .netrc machine api.twitter.com login YOUR_TWITTER_USER_NAME password YOUR_TWITTER_PASSWORD machine semifor.twitter.com login semifor password SUPERSECRET # in your perl program $nt = Net::Twitter->new(netrc => 1); $nt = Net::Twitter->new(netrc => 'semifor.twitter.com'); netrc_machine (Optional) Sets the "machine" entry to look up in ".netrc" when "> is used. Defaults to "api.twitter.com". decode_html_entities Twitter encodes HTML entities in the "text" field of statuses. Set this option to 1 to have them automatically decoded. Default 0. credentials($username, $password) Set the credentials for Basic Authentication. This is helpful for managing multiple accounts. ua Provides access to the constructed user agent object used internally by "Net::Twitter". Use it with caution. AUTHENTICATION Twitter currently provides two authentication strategies: Basic Authentication and OAuth. OAuth is officially in beta, however, Twitter has expressed a desire to deprecate Basic Authentication in the future, so consider using OAuth in your applications. To set up Basic Authentication in "Net::Twitter", provide the "username" and "password" options to "new" or call the "credentials" method. To set up OAuth, include the "OAuth" trait and include the "consumer_key" and "consumer_secret" options to "new". See Net::Twitter::Role::OAuth for more information on using OAuth, including examples. In addition to the arguments specified for each API method described below, an additional "authenticate" parameter can be passed. To request an "Authorization" header, pass "authenticated => 1"; to suppress an authentication header, pass "authentication => 0". Even if requested, an Authorization header will not be added if there are no user credentials (username and password for Basic Authentication; access tokens for OAuth). This is probably only useful for the "rate_limit_status" method in the REST API, since it returns different values for an authenticated and a non-authenticated call. API METHODS AND ARGUMENTS Most Twitter API methods take parameters. All Net::Twitter API methods will accept a HASH ref of named parameters as specified in the Twitter API documentation. For convenience, many Net::Twitter methods accept simple positional arguments as documented, below. The positional parameter passing style is optional; you can always use the named parameters in a hash ref if you prefer. For example, the REST API method "update" has one required parameter, "status". You can call "update" with a HASH ref argument: $nt->update({ status => 'Hello world!' }); Or, you can use the convenient form: $nt->update('Hello world!'); The "update" method also has an optional parameter, "in_reply_to_status_id". To use it, you must use the HASH ref form: $nt->update({ status => 'Hello world!', in_reply_to_status_id => $reply_to }); Convenience form is provided for the required parameters of all API methods. So, these two calls are equivalent: $nt->friendship_exists({ user_a => $fred, user_b => $barney }); $nt->friendship_exists($fred, $barney); Many API methods have aliases. You can use the API method name, or any of its aliases, as you prefer. For example, these calls are all equivalent: $nt->friendship_exists($fred, $barney); $nt->relationship_exists($fred, $barney); $nt->follows($fred, $barney); Aliases support both the HASH ref and convenient forms: $nt->follows({ user_a => $fred, user_b => $barney }); Cursors and Paging Some methods return partial results a page at a time. Originally, methods that returned partial results used a "page" parameter. A more recent addition to the Twitter API for retrieving multiple pages uses the "cursor" parameter. Usually, a method uses either the "page" parameter or the "cursor" parameter, but not both. There have been exceptions to this rule when Twitter deprecates the use of "page" for a method in favor of "cursor". In that case, both methods may work during a transition period. So, if a method supports both, you should always use the "cursor" parameter. Paging For methods that support paging, the first page is returned by passing "page => 1", the second page by passing "page => 2", etc. If no "page" parameter is passed, the first page is returned. Here's an example that demonstrates how to obtain all favorites in a loop: my @favs; for ( my $page = 1; ; ++$page ) { my $r = $nt->favorites({ page => $page }); last unless @$r; push @favs, @$r; } Cursors Cursoring employs a different strategy. To obtain the first page of results, pass "cursor => -1". Twitter returns a reference to a hash that includes entries "next_cursor", "previous_cursor", and an entry with a reference to an array containing a page of the requested items. The key for the array reference will be named "users", "ids", or something similar depending upon the type of returned items. For example, when "cursor" parameter is used with the "followers_ids" method, the returned in hash entry "ids". The "next_cursor" value can be used in a subsequent call to obtain the next page of results. When you have obtained the last page of results, "next_cursor" will be 0. Likewise, you can use the value for "previous_cursor" to obtain the previous page of results. When you have obtained the first page, "previous_cursor" will be 0. Here's an example that demonstrates how to obtain all follower IDs in a loop using the "cursor" parameter: my @ids; for ( my $cursor = -1, my $r; $cursor; $cursor = $r->{next_cursor} ) { $r = $nt->followers_ids({ cursor => $cursor }); push @ids, @{ $r->{ids} }; } Synthetic Arguments In addition to the arguments described in the Twitter API Documentation for each API method, Net::Twitter supports additional *synthetic* arguments. authenticate When set to 1, Net::Twitter will provide an Authorization header for the API call; when set to 0, it will suppress the Authentication header. This argument overrides the defined authentication behavior for the API method. It is probably only useful for the "rate_limit_satus" method which returns different values for authenticated and unauthenticated calls. See "AUTHENTICATION" for more details. since API methods that accept the "since_id" argument will also accept the synthetic "since" argument, instead. "since" may be a "Date::Time" object, an epoch time (the number of seconds since the system epoch), or a string in the same format returned by Twitter for the "created_at" attribute. Only statuses with a "created_at" time greater than "since" will be returned by the API call. REST API Methods These methods are provided when trait "API::REST" is included in the "traits" option to "new". Several of these methods accept a user ID as the "id" parameter. The user ID can be either a screen name, or the users numeric ID. To disambiguate, use the "screen_name" or "user_id" parameters, instead. For example, These calls are equivalent: $nt->create_friend('perl_api'); # screen name $nt->create_friend(1564061); # numeric ID $nt->create_friend({ id => 'perl_api' }); $nt->create_friend({ screen_name => 'perl_api' }); $nt->create_friend({ user_id => 1564061 }); However user_id 911 and screen_name 911 are separate Twitter accounts. These calls are NOT equivalent: $nt->create_friend(911); # interpreted as screen name $nt->create_friend({ user_id => 911 }); # screen name: richellis Whenever the "id" parameter is required and "user_id" and "screen_name" are also parameters, using any one of them satisfies the requirement. block_exists block_exists(id) Parameters: id, user_id, screen_name Required: id Returns if the authenticating user is blocking a target user. Will return the blocked user's object if a block exists, and error with HTTP 404 response code otherwise. Returns: BasicUser blocking blocking(page) Parameters: page Required: *none* Returns an array of user objects that the authenticating user is blocking. Returns: ArrayRef[BasicUser] blocking_ids Parameters: *none* Required: *none* Returns an array of numeric user ids the authenticating user is blocking. Returns: ArrayRef[Int] create_block create_block(id) Parameters: id Required: id Blocks the user specified in the ID parameter as the authenticating user. Returns the blocked user when successful. You can find out more about blocking in the Twitter Support Knowledge Base. Returns: BasicUser create_favorite create_favorite(id) Parameters: id Required: id Favorites the status specified in the ID parameter as the authenticating user. Returns the favorite status when successful. Returns: Status create_friend create_friend(id) alias: follow_new Parameters: id, user_id, screen_name, follow Required: id Befriends the user specified in the ID parameter as the authenticating user. Returns the befriended user when successful. Returns a string describing the failure condition when unsuccessful. Returns: BasicUser create_saved_search create_saved_search(query) Parameters: query Required: query Creates a saved search for the authenticated user. Returns: SavedSearch destroy_block destroy_block(id) Parameters: id Required: id Un-blocks the user specified in the ID parameter as the authenticating user. Returns the un-blocked user when successful. Returns: BasicUser destroy_direct_message destroy_direct_message(id) Parameters: id Required: id Destroys the direct message specified in the required ID parameter. The authenticating user must be the recipient of the specified direct message. Returns: DirectMessage destroy_favorite destroy_favorite(id) Parameters: id Required: id Un-favorites the status specified in the ID parameter as the authenticating user. Returns the un-favorited status. Returns: Status destroy_friend destroy_friend(id) alias: unfollow Parameters: id, user_id, screen_name Required: id Discontinues friendship with the user specified in the ID parameter as the authenticating user. Returns the un-friended user when successful. Returns a string describing the failure condition when unsuccessful. Returns: BasicUser destroy_saved_search destroy_saved_search(id) Parameters: id Required: id Destroys a saved search. The search, specified by "id", must be owned by the authenticating user. Returns: SavedSearch destroy_status destroy_status(id) Parameters: id Required: id Destroys the status specified by the required ID parameter. The authenticating user must be the author of the specified status. Returns: Status direct_messages Parameters: since_id, max_id, count, page Required: *none* Returns a list of the 20 most recent direct messages sent to the authenticating user including detailed information about the sending and recipient users. Returns: ArrayRef[DirectMessage] disable_notifications disable_notifications(id) Parameters: id Required: id Disables notifications for updates from the specified user to the authenticating user. Returns the specified user when successful. Returns: BasicUser enable_notifications enable_notifications(id) Parameters: id Required: id Enables notifications for updates from the specified user to the authenticating user. Returns the specified user when successful. Returns: BasicUser end_session Parameters: *none* Required: *none* Ends the session of the authenticating user, returning a null cookie. Use this method to sign users out of client-facing applications like widgets. Returns: Error favorites Parameters: id, page Required: *none* Returns the 20 most recent favorite statuses for the authenticating user or user specified by the ID parameter. Returns: ArrayRef[Status] followers Parameters: id, user_id, screen_name, cursor Required: *none* Returns a reference to an array of the user's followers. If "id", "user_id", or "screen_name" is not specified, the followers of the authenticating user are returned. The returned users are ordered from most recently followed to least recently followed. Use the optional "cursor" parameter to retrieve users in pages of 100. When the "cursor" parameter is used, the return value is a reference to a hash with keys "previous_cursor", "next_cursor", and "users". The value of "users" is a reference to an array of the user's friends. The result set isn't guaranteed to be 100 every time as suspended users will be filtered out. Set the optional "cursor" parameter to -1 to get the first page of users. Set it to the prior return's value of "previous_cursor" or "next_cursor" to page forward or backwards. When there are no prior pages, the value of "previous_cursor" will be 0. When there are no subsequent pages, the value of "next_cursor" will be 0. Returns: HashRef|ArrayRef[User] followers_ids followers_ids(id) Parameters: id, user_id, screen_name, cursor Required: id Returns a reference to an array of numeric IDs for every user following the specified user. Use the optional "cursor" parameter to retrieve IDs in pages of 5000. When the "cursor" parameter is used, the return value is a reference to a hash with keys "previous_cursor", "next_cursor", and "ids". The value of "ids" is a reference to an array of IDS of the user's followers. Set the optional "cursor" parameter to -1 to get the first page of IDs. Set it to the prior return's value of "previous_cursor" or "next_cursor" to page forward or backwards. When there are no prior pages, the value of "previous_cursor" will be 0. When there are no subsequent pages, the value of "next_cursor" will be 0. Returns: HashRef|ArrayRef[Int] friends alias: following Parameters: id, user_id, screen_name, cursor Required: *none* Returns a reference to an array of the user's friends. If "id", "user_id", or "screen_name" is not specified, the friends of the authenticating user are returned. The returned users are ordered from most recently followed to least recently followed. Use the optional "cursor" parameter to retrieve users in pages of 100. When the "cursor" parameter is used, the return value is a reference to a hash with keys "previous_cursor", "next_cursor", and "users". The value of "users" is a reference to an array of the user's friends. The result set isn't guaranteed to be 100 every time as suspended users will be filtered out. Set the optional "cursor" parameter to -1 to get the first page of users. Set it to the prior return's value of "previous_cursor" or "next_cursor" to page forward or backwards. When there are no prior pages, the value of "previous_cursor" will be 0. When there are no subsequent pages, the value of "next_cursor" will be 0. Returns: Hashref|ArrayRef[User] friends_ids friends_ids(id) alias: following_ids Parameters: id, user_id, screen_name, cursor Required: id Returns a reference to an array of numeric IDs for every user followed the specified user. Use the optional "cursor" parameter to retrieve IDs in pages of 5000. When the "cursor" parameter is used, the return value is a reference to a hash with keys "previous_cursor", "next_cursor", and "ids". The value of "ids" is a reference to an array of IDS of the user's friends. Set the optional "cursor" parameter to -1 to get the first page of IDs. Set it to the prior return's value of "previous_cursor" or "next_cursor" to page forward or backwards. When there are no prior pages, the value of "previous_cursor" will be 0. When there are no subsequent pages, the value of "next_cursor" will be 0. Returns: HashRef|ArrayRef[Int] friends_timeline alias: following_timeline Parameters: since_id, max_id, count, page Required: *none* Returns the 20 most recent statuses posted by the authenticating user and that user's friends. This is the equivalent of /home on the Web. Returns: ArrayRef[Status] friendship_exists friendship_exists(user_a, user_b) alias: relationship_exists alias: follows Parameters: user_a, user_b Required: user_a, user_b Tests for the existence of friendship between two users. Will return true if user_a follows user_b, otherwise will return false. Returns: Bool geo_id geo_id(id) Parameters: id Required: id Returns details of a place returned from the "reverse_geocode" method. Returns: HashRef home_timeline Parameters: since_id, max_id, count, page Required: *none* Returns the 20 most recent statuses, including retweets, posted by the authenticating user and that user's friends. This is the equivalent of /timeline/home on the Web. Returns: ArrayRef[Status] mentions alias: replies Parameters: since_id, max_id, count, page Required: *none* Returns the 20 most recent mentions (statuses containing @username) for the authenticating user. Returns: ArrayRef[Status] new_direct_message new_direct_message(user, text) Parameters: user, text, screen_name, user_id Required: user, text Sends a new direct message to the specified user from the authenticating user. Requires both the user and text parameters. Returns the sent message when successful. In order to support numeric screen names, the "screen_name" or "user_id" parameters may be used instead of "user". Returns: DirectMessage public_timeline Parameters: *none* Required: *none* Returns the 20 most recent statuses from non-protected users who have set a custom user icon. Does not require authentication. Note that the public timeline is cached for 60 seconds so requesting it more often than that is a waste of resources. If user credentials are provided, "public_timeline" calls are authenticated, so they count against the authenticated user's rate limit. Use "->public_timeline({ authenticate => 0 })" to make an unauthenticated call which will count against the calling IP address' rate limit, instead. Returns: ArrayRef[Status] rate_limit_status Parameters: *none* Required: *none* Returns the remaining number of API requests available to the authenticated user before the API limit is reached for the current hour. Use "->rate_limit_status({ authenticate => 0 })" to force an unauthenticated call, which will return the status for the IP address rather than the authenticated user. (Note: for a web application, this is the server's IP address.) Returns: RateLimitStatus report_spam report_spam(id) Parameters: id, user_id, screen_name Required: id The user specified in the id is blocked by the authenticated user and reported as a spammer. Returns: User retweet retweet(id) Parameters: id Required: id Retweets a tweet. Requires the id parameter of the tweet you are retweeting. Returns the original tweet with retweet details embedded. Returns: Status retweeted_by_me Parameters: since_id, max_id, count, page Required: *none* Returns the 20 most recent retweets posted by the authenticating user. Returns: ArrayRef[Status] retweeted_to_me Parameters: since_id, max_id, count, page Required: *none* Returns the 20 most recent retweets posted by the authenticating user's friends. Returns: ArrayRef[Status] retweets retweets(id) Parameters: id, count Required: id Returns up to 100 of the first retweets of a given tweet. Returns: Arrayref[Status] retweets_of_me alias: retweeted_of_me Parameters: since_id, max_id, count, page Required: *none* Returns the 20 most recent tweets of the authenticated user that have been retweeted by others. Returns: ArrayRef[Status] reverse_geocode reverse_geocode(lat, long) Parameters: lat, long, accuracy, granularity, max_results Required: lat, long Search for places (cities and neighborhoods) that can be attached to a statuses/update. Given a latitude and a longitude, return a list of all the valid places that can be used as a place_id when updating a status. Conceptually, a query can be made from the user's location, retrieve a list of places, have the user validate the location he or she is at, and then send the ID of this location up with a call to statuses/update. There are multiple granularities of places that can be returned -- "neighborhoods", "cities", etc. At this time, only United States data is available through this method. lat Required. The latitude to query about. Valid ranges are -90.0 to +90.0 (North is positive) inclusive. long Required. The longitude to query about. Valid ranges are -180.0 to +180.0 (East is positive) inclusive. accuracy Optional. A hint on the "region" in which to search. If a number, then this is a radius in meters, but it can also take a string that is suffixed with ft to specify feet. If this is not passed in, then it is assumed to be 0m. If coming from a device, in practice, this value is whatever accuracy the device has measuring its location (whether it be coming from a GPS, WiFi triangulation, etc.). granularity Optional. The minimal granularity of data to return. If this is not passed in, then "neighborhood" is assumed. "city" can also be passed. max_results Optional. A hint as to the number of results to return. This does not guarantee that the number of results returned will equal max_results, but instead informs how many "nearby" results to return. Ideally, only pass in the number of places you intend to display to the user here. Returns: HashRef saved_searches Parameters: *none* Required: *none* Returns the authenticated user's saved search queries. Returns: ArrayRef[SavedSearch] sent_direct_messages Parameters: since_id, max_id, page Required: *none* Returns a list of the 20 most recent direct messages sent by the authenticating user including detailed information about the sending and recipient users. Returns: ArrayRef[DirectMessage] show_friendship show_friendship(id) alias: show_relationship Parameters: source_id, source_screen_name, target_id, target_id_name Required: id Returns detailed information about the relationship between two users. Returns: Relationship show_saved_search show_saved_search(id) Parameters: id Required: id Retrieve the data for a saved search, by ID, owned by the authenticating user. Returns: SavedSearch show_status show_status(id) Parameters: id Required: id Returns a single status, specified by the id parameter. The status's author will be returned inline. Returns: Status show_user show_user(id) Parameters: id Required: id Returns extended information of a given user, specified by ID or screen name as per the required id parameter. This information includes design settings, so third party developers can theme their widgets according to a given user's preferences. You must be properly authenticated to request the page of a protected user. Returns: ExtendedUser test Parameters: *none* Required: *none* Returns the string "ok" status code. Returns: Str trends_available Parameters: lat, long Required: *none* Returns the locations with trending topic information. The response is an array of "locations" that encode the location's WOEID (a Yahoo! Where On Earth ID ) and some other human-readable information such as a the location's canonical name and country. When the optional "lat" and "long" parameters are passed, the available trend locations are sorted by distance from that location, nearest to farthest. Use the WOEID returned in the location object to query trends for a specific location. Returns: ArrayRef[Location] trends_location trends_location(woeid) Parameters: woeid Required: woeid Returns the top 10 trending topics for a specific location. The response is an array of "trend" objects that encode the name of the trending topic, the query parameter that can be used to search for the topic on Search, and the direct URL that can be issued against Search. This information is cached for five minutes, and therefore users are discouraged from querying these endpoints faster than once every five minutes. Global trends information is also available from this API by using a WOEID of 1. Returns: ArrayRef[Trend] update update(status) Parameters: status, lat, long, place_id, display_coordinates, in_reply_to_status_id Required: status Updates the authenticating user's status. Requires the status parameter specified. A status update with text identical to the authenticating user's current status will be ignored. status Required. The text of your status update. URL encode as necessary. Statuses over 140 characters will cause a 403 error to be returned from the API. in_reply_to_status_id Optional. The ID of an existing status that the update is in reply to. o Note: This parameter will be ignored unless the author of the tweet this parameter references is mentioned within the status text. Therefore, you must include @username, where username is the author of the referenced tweet, within the update. lat Optional. The location's latitude that this tweet refers to. The valid ranges for latitude is -90.0 to +90.0 (North is positive) inclusive. This parameter will be ignored if outside that range, if it is not a number, if geo_enabled is disabled, or if there not a corresponding long parameter with this tweet. long Optional. The location's longitude that this tweet refers to. The valid ranges for longitude is -180.0 to +180.0 (East is positive) inclusive. This parameter will be ignored if outside that range, if it is not a number, if geo_enabled is disabled, or if there not a corresponding lat parameter with this tweet. place_id Optional. The place to attach to this status update. Valid place_ids can be found by querying "reverse_geocode". display_coordinates Optional. By default, geo-tweets will have their coordinates exposed in the status object (to remain backwards compatible with existing API applications). To turn off the display of the precise latitude and longitude (but keep the contextual location information), pass "display_coordinates =" 0> on the status update. Returns: Status update_delivery_device update_delivery_device(device) Parameters: device Required: device Sets which device Twitter delivers updates to for the authenticating user. Sending none as the device parameter will disable IM or SMS updates. Returns: BasicUser update_profile Parameters: name, email, url, location, description Required: *none* Sets values that users are able to set under the "Account" tab of their settings page. Only the parameters specified will be updated; to only update the "name" attribute, for example, only include that parameter in your request. Returns: ExtendedUser update_profile_background_image update_profile_background_image(image) Parameters: image Required: image Updates the authenticating user's profile background image. The "image" parameter must be an arrayref with the same interpretation as the "image" parameter in the "update_profile_image" method. See that method's documentation for details. Returns: ExtendedUser update_profile_colors Parameters: profile_background_color, profile_text_color, profile_link_color, profile_sidebar_fill_color, profile_sidebar_border_color Required: *none* Sets one or more hex values that control the color scheme of the authenticating user's profile page on twitter.com. These values are also returned in the /users/show API method. Returns: ExtendedUser update_profile_image update_profile_image(image) Parameters: image Required: image Updates the authenticating user's profile image. The "image" parameter is an arrayref with the following interpretation: [ $file ] [ $file, $filename ] [ $file, $filename, Content_Type => $mime_type ] [ undef, $filename, Content_Type => $mime_type, Content => $raw_image_data ] The first value of the array ($file) is the name of a file to open. The second value ($filename) is the name given to Twitter for the file. If $filename is not provided, the basename portion of $file is used. If $mime_type is not provided, it will be provided automatically using LWP::MediaTypes::guess_media_type(). $raw_image_data can be provided, rather than opening a file, by passing "undef" as the first array value. Returns: ExtendedUser user_timeline Parameters: id, user_id, screen_name, since_id, max_id, count, page Required: *none* Returns the 20 most recent statuses posted from the authenticating user. It's also possible to request another user's timeline via the id parameter. This is the equivalent of the Web /archive page for your own user, or the profile page for a third party. Returns: ArrayRef[Status] users_search users_search(q) alias: find_people alias: search_users Parameters: q, per_page, page Required: q Run a search for users similar to Find People button on Twitter.com; the same results returned by people search on Twitter.com will be returned by using this API (about being listed in the People Search). It is only possible to retrieve the first 1000 matches from this API. Returns: ArrayRef[Users] verify_credentials Parameters: *none* Required: *none* Returns an HTTP 200 OK response code and a representation of the requesting user if authentication was successful; returns a 401 status code and an error message if not. Use this method to test if supplied user credentials are valid. Returns: ExtendedUser Search API Methods These methods are provided when trait "API::Search" is included in the "traits" option to "new". search search(q) Parameters: q, callback, lang, rpp, page, since_id, geocode, show_user Required: q Returns a HASH reference with some meta-data about the query including the "next_page", "refresh_url", and "max_id". The statuses are returned in "results". To iterate over the results, use something similar to: my $r = $nt->search($searh_term); for my $status ( @{$r->{results}} ) { print "$status->{text}\n"; } Returns: HashRef trends Parameters: *none* Required: *none* Returns the top ten queries that are currently trending on Twitter. The response includes the time of the request, the name of each trending topic, and the url to the Twitter Search results page for that topic. Returns: ArrayRef[Query] trends_current trends_current(exclude) Parameters: exclude Required: *none* Returns the current top ten trending topics on Twitter. The response includes the time of the request, the name of each trending topic, and query used on Twitter Search results page for that topic. Returns: HashRef trends_daily Parameters: date, exclude Required: *none* Returns the top 20 trending topics for each hour in a given day. Returns: HashRef trends_weekly Parameters: date, exclude Required: *none* Returns the top 30 trending topics for each day in a given week. Returns: HashRef TwitterVision API Methods These methods are provided when trait "API::TwitterVision" is included in the "traits" option to "new". current_status current_status(id) Parameters: id, callback Required: id Get the current location and status of a user. Returns: HashRef update_twittervision update_twittervision(location) Parameters: location Required: location Updates the location for the authenticated user. Returns: HashRef Lists API For Lists API support, add trait "API::Lists" to the "traits" option in "new". For full documentation of the Lists API, see Net::Twitter::Role::API::Lists. use Net::Twitter; my $nt = Net::Twitter->new(traits => ['API::Lists'], ...); $list = $nt->create_list($owner, { name => $name, description => $desc }); $list = $nt->update_list($owner, $list_id, { description => $desc }); $lists = $nt->get_lists($owner); $lists = $nt->list_lists($owner); $list = $nt->get_list($owner, $list_id); $list = $nt->delete_list($owner, $list_id); $statuses = $nt->list_statuses($owner, $list_id); $lists = $nt->list_memberships($owner); $lists = $nt->list_subscriptions($owner); $users = $nt->list_members($owner, $list_id); $user_or_undef = $nt->list_members($owner, $list_id, { id => $user_id }); $user = $nt->add_list_member($owner, $list_id, $user_id); $user = $nt->delete_list_member($owner, $list_id, $user_id); $user = $nt->remove_list_member($owner, $list_id, $user_id); $user_or_undef = $nt->is_list_member($owner, $list_id, $user_id); $users = $nt->list_subscribers($owner, $list_id); $list = $nt->subscribe_list($owner, $list_id); $list = $nt->unsubscribe_list($owner, $list_id); $user_or_undef = $nt->is_subscribed_list($owner, $list_id, $user_id); $user_or_undef = $nt->is_list_subscriber($owner, $list_id, $user_id); LEGACY COMPATIBILITY This version of "Net::Twitter" automatically includes the "Legacy" trait if no "traits" option is provided to "new". Therefore, these 2 calls are currently equivalent: $nt = Net::Twitter->new(username => $user, password => $passwd); $nt = Net::Twitter->new( username => $user, password => $passwd, traits => ['Legacy'], ); Thus, existing applications written for a prior version of "Net::Twitter" should continue to run, without modification, with this version. In a future release, the default traits may change. Prior to that change, however, a nearer future version will add a warning if no "traits" option is provided to "new". To avoid this warning, add an appropriate "traits" option to your existing application code. ERROR HANDLING There are currently two strategies for handling errors: throwing exceptions and wrapping errors. Exception handling is the newer, recommended strategy. Wrapping Errors When trait "WrapError" is specified (or "Legacy", which includes trait "WrapError"), "Net::Twitter" returns undef on error. To retrieve information about the error, use methods "http_code", "http_message", and "get_error". These methods are described in the Net::Twitter::Role::WrapError. if ( my $followers = $nt->followers ) { for my $follower ( @$followers ) { #... } } else { warn "HTTP message: ", $nt->http_message, "\n"; } Since an error is stored in the object instance, this error handling strategy is problematic when using a user agent like "LWP::UserAgent::POE" that provides concurrent requests. The error for one request can be overwritten by a concurrent request before you have an opportunity to access it. Exception Handling When "Net::Twitter" encounters a Twitter API error or a network error, it throws a "Net::Twitter::Error" object. You can catch and process these exceptions by using "eval" blocks and testing $@: eval { my $statuses = $nt->friends_timeline(); # this might die! for my $status ( @$statuses ) { #... } }; if ( $@ ) { # friends_timeline encountered an error if ( blessed $@ && $@->isa('Net::Twitter::Error') ) { #... use the thrown error obj warn $@->error; } else { # something bad happened! die $@; } } "Net::Twitter::Error" stringifies to something reasonable, so if you don't need detailed error information, you can simply treat $@ as a string: eval { $nt->update($status) }; if ( $@ ) { warn "update failed because: $@\n"; } FAQ Why does "->followers({ screen_name => $friend })" return *my* followers instead of $friends's? First, check carefully to make sure you've spelled "screen_name" correctly. Twitter sometimes discards parameters it doesn't recognize. In this case, the result is a list of your own followers---the same thing that would happen if you called "followers" without the "screen_name" parameter. How do I use the "geocode" parameter in the Search API? The "geocode" parameter value includes a latitude, longitude, and radius separated with commas. $r = $nt->search({ geocode => "45.511795,-122.675629,25mi" }); How do I get Twitter to display something other than "from Perl Net::Twitter"? If you set the source parameter to "api", twitter will display "from API", and if you set it to the empty string, twitter will display, "from web". $nt = Net::Twitter->new(netrc => 1,legacy => 0,ssl => 1,source => 'api'); $nt->update('A post with the source parameter overridden.'); # result: http://twitter.com/semifor_test/status/6541105458 $nt = Net::Twitter->new(netrc => 1,legacy => 0,ssl => 1,source => ''); $nt->update('A post with the source parameter overridden.'); # result: http://twitter.com/semifor_test/status/6541257224 If you want something other than "Net::Twitter", "API", or "web", you need to register an application and use OAuth authentication. If you do that, you can have any name you choose for the application printed as the source. Since rolling out OAuth, Twitter has stopped issuing new registered source parameters, only existing register source parameters are valid. SEE ALSO Net::Twitter::Error The "Net::Twitter" exception object. This is the official Twitter API documentation. It describes the methods and their parameters in more detail and may be more current than the documentation provided with this module. LWP::UserAgent::POE This LWP::UserAgent compatible class can be used in POE based application along with Net::Twitter to provide concurrent, non-blocking requests. Catalyst::Authentication::Credential::Twitter This module, by Jesse Stay, provides Twitter OAuth authentication support for the popular Catalyst web application framework.
