UNDER CONSTRUCTION Though functional, this software is still in the process of being documented and should, therefore, be considered a work in progress. NAME WebService::Shippo - Shippo API Client VERSION version 0.0.18 SYNOPIS Note: though scripts and modules must always "use WebService::Shippo;" to import the client software, the "WebService::" portion of that package namespace may be dropped when subsequently referring to the main package or any of its resource classes. For example, "WebService::Shippo::Address" and "Shippo::Address" refer to the same class. To compel the developer to continue using the "WebService::" prefix does seem like an unreasonable form of torture, besides which, it probably doesn't leave much scope for indenting code as some class names would be very long. Use it, or don't use it. It's entirely up to you. use strict; use LWP::UserAgent; use WebService::Shippo; # If you aren't using a config file or the environment (SHIPPO_TOKEN=...) # to supply your API key, you can do so here: Shippo->api_key('PASTE YOUR AUTH TOKEN HERE') unless Shippo->api_key; # Complete example illustrating the the process of Shipment creation # through to label generation. # # Create a Shipment object: my $shipment = Shippo::Shipment->create( object_purpose => 'PURCHASE', address_from => { object_purpose => 'PURCHASE', name => 'Shawn Ippotle', company => 'Shippo', street1 => '215 Clayton St.', city => 'San Francisco', state => 'CA', zip => '94117', country => 'US', phone => '+1 555 341 9393', email => 'shippotle@goshippo.com' }, address_to => { object_purpose => 'PURCHASE', name => 'Mr Hippo', company => '', street1 => 'Broadway 1', street2 => '', city => 'New York', state => 'NY', zip => '10007', country => 'US', phone => '+1 555 341 9393', email => 'mrhippo@goshippo.com' }, parcel => { length => '5', width => '5', height => '5', distance_unit => 'in', weight => '2', mass_unit => 'lb' } ); # Retrieve shipping rates and select preferred rate: my $rates = Shippo::Shipment->get_shipping_rates( $shipment->object_id ); my $preferred_rate = $rates->item(2); # Purchase label at the preferred rate: my $transaction = Shippo::Transaction->create( rate => $preferred_rate->object_id, label_file_type => 'PNG', ); # Get the shipping label: my $label_url = Shippo::Transaction->get_shipping_label( $transaction->object_id ); my $browser = LWP::UserAgent->new; $browser->get( $transaction->label_url, ':content_file' => './sample.png' ); # Print the transaction object... print "Transaction:\n", $transaction->to_json(1); # '1' makes the JSON readable --[content dumped to console]-- Transaction: { "commercial_invoice_url" : null, "customs_note" : "", "label_url" : "https://shippo-delivery-east.s3.amazonaws.com/da2e68fe85f94a9ebca458d9f9d 2446b.PNG?Signature=BjD2JMQt0ATd5jUWAKm%2B6FHcBPM%3D&Expires=1477323662&AWSAccessKeyId=AKIA JGLCC5MYLLWIG42A", "messages" : [], "metadata" : "", "notification_email_from" : false, "notification_email_other" : "", "notification_email_to" : false, "object_created" : "2015-10-25T15:41:01.182Z", "object_id" : "da2e68fe85f94a9ebca458d9f9d2446b", "object_owner" : "******@*********.***", "object_state" : "VALID", "object_status" : "SUCCESS", "object_updated" : "2015-10-25T15:41:02.494Z", "order" : null, "pickup_date" : null, "rate" : "3c76e81733d7417b9a801ce957f4219d", "submission_note" : "", "tracking_history" : [], "tracking_number" : "9499907123456123456781", "tracking_status" : { "object_created" : "2015-10-25T15:41:02.451Z", "object_id" : "02ce6dbd6d5a48cfb764fdeb0cb6e404", "object_updated" : "2015-10-25T15:41:02.451Z", "status" : "UNKNOWN", "status_date" : null, "status_details" : "" }, "tracking_url_provider" : "https://tools.usps.com/go/TrackConfirmAction_input?origTrackN um=9499907123456123456781", "was_test" : true } --[end of content]-- The sample code in this synopsis produced the following label (at a much larger size, of course), which was then saved as a PNG file using the "LWP::UserAgent" package: * DESCRIPTION Shippo connects you with multiple shipping providers (USPS, UPS and Fedex, for example) through one interface, offering you great discounts on a selection of shipping rates. You can sign-up for an account at . The Shippo API can be used to automate and customize shipping capabilities for your e-commerce store or marketplace, enabling you to retrieve shipping rates, create and purchase shipping labels, track packages, and much more. Though Shippo *do* offer official API clients for a bevy of major languages, the venerable Perl 5 was not included in that list. This community offering attempts to correct that omission ;-) API Resources Access to all Shippo API resources is via URLs relative to the same encrypted API endpoint (https://api.goshippo.com/v1/). There are resource item classes to help with the nitty-gritty of interacting each type of resource: * Addresses * Parcels * Shipments * Rates * Transactions * Customs Items * Customs Declarations * Refunds * Manifests * Carrier Accounts Each item class has a related collection class with a similar name *in the plural form*. The rationale behind this is that the Shippo API can be used to retrieve single objects with the "fetch" method, and collections of objects with the "all" method, and different behaviours may be applied to collections, which is why both forms exist. Request & Response Data The Perl client ensures that requests are properly encoded and passed to the correct API endpoints using appropriate HTTP methods. There is documentation for each API resource, containing more details on the values accepted by and returned for a given resource (see "FULL API DOCUMENTATION"). All API requests return responses encoded as JSON strings, which the client converts into Perl blessed object references of the correct type. As a rule, any resource attribute documented in the API specification will have an accessor of the same same in a Perl instance of that object. REST & Disposable Objects The Shippo API is built with simplicity and RESTful principles in mind: POST requests are used to create objects, GET requests to fetch and list objects, and PUT requests to update objects. The Perl client provides "create", "fetch", "all" and "update" methods for use with resource objects that permit such operations. Addresses, Parcels, Shipments, Rates, Transactions, Refunds, Customs Items and Customs Declarations are disposable objects. This means that once you create an object, you cannot change it. Instead, create a new one with the desired values. Carrier Accounts are the exception and may be updated via PUT requests. METHODS api_key Get or set the key used by API requests for Shippo's token-based authentication. This is Shippo's preferred method of authentication. * Return the token currently being used for authentication. my $api_key = Shippo->api_key; * Set the token to be used for authentication. Shippo->api_key($auth_token); The "api_key" method is chainable when used as a setter. api_credentials Get or set the login credentials used by API requests for Shippo's legacy authentication. Legacy authentication means encoding the HTTP Authorization header for Basic Authentication so, even though requests and repsonses are encrypted, you should still consider using the token-based authentication instead (see "api_key"). * Return the login credentials currently being used for authentication. my ($username, $password) = Shippo->api_credentials; * Set the credentials to be used for authentication. Shippo->api_credentials($username, $password); The "api_credentials" method is chainable when used as a setter. Whenever a configuration specifies both token and login credentials, the client will always favour token-based authentication. If "api_key" and "api_credentials" are both set manually then it is the most recently set mechanism that defines the HTTP Authorization header. pretty Get or set the state of the attribute influencing the default readability of objects serialized as JSON using the "to_json" method or automatic stringification. * Return the current state of the "pretty" attribute. my $boolean = Shippo->pretty; * Set the state of the "pretty" attribute. Shippo->pretty($boolean); Note: the "to_json" method also takes optional boolean argument that may be set to "true" or "false" to achieve the same effect for a single serialization, regardless of the default currently in force. response my $last_response = Shippo->response; Returns a copy of the "HTTP::Response" resulting from the most recent request. EXPORTS The "WebService::Shippo" package exports a number of helpful subroutines by default: true my $fedex_account = Shippo::CarrierAccount->create( carrier => 'fedex', account_id => '', parameters => { meter => '' }, test => true, active => true ); Returns a scalar value which will evaluate to true. Since the *lingua franca* connecting Shippo's API and the Perl client is JSON, it can feel more natural to think in those terms. Thus, "true" may be used in place of 1. Now, when creating a new object from a JSON example, any literal and accidental use of "true" or "false" is much less likely to result in misery. See Ingy's boolean package for more guidance. false my $fedex_account = Shippo::CarrierAccount->create( carrier => 'fedex', account_id => '', parameters => { meter => '' }, test => false, active => false ); Returns a scalar value which will evaluate to false. Since the *lingua franca* connecting Shippo's API and the Perl client is JSON, it can feel more natural to think in those terms. Thus, "false" may be used in place of 0. Now, when creating a new object from a JSON example, any literal and accidental use of "true" or "false" is much less likely to result in misery. See Ingy's boolean package for more guidance. boolean my $bool = boolean($value); Casts a scalar value to a boolean value ("true" or "false"). See Ingy's boolean package for more guidance. callback Shippo::CarrierAccounts->all(callback { $_->enable_test_mode; }); Returns a blessed "sub" suitable for use as a callback. Some methods accept optional blocking callbacks in order to facilitate list transformations, so this package makes &Params::Callbacks::callback available for use. See Params::Callbacks for more guidance. CONFIGURATION While the client does provide "api_key" and "api_credentials" methods to help with authentication, hard-coding such calls in anything more mission critical than a simple test script may *not* be the best way to go. As soon as it is imported, one of the first things the client does is search a number of locations for a YAML-encoded configuration file. The first one it finds is loaded. In order, the locations searched are as follows: * "./.shipporc" * "/*path*/*to*/*home*/.shipporc" * "/*etc*/shipporc" * "/*path*/*to*/*perl*/*module*/*install*/*lib*/WebService/Shippo/Config .yml" The configuration file is very simple and needs to have the following structure, though not all elements are mandatory: --- username: martymcfly@pinheads.org password: yadayada private_token: f0e1d2c3b4a5968778695a4b3c2d1e0f96877869 public_token: 96877869f0e1d2c3b4a5968778695a4b3c2d1e0f default_token: private_token At a minimum, your configuration should define values for "private_token" and "public_token". These are your Shippo Private and Publishable Auth tokens, which are found on your Shippo API page .
