CanadaPost REST API V3 Wrapper

A Ruby wrapper for the CanadaPost REST API. Based extensively off the fedex gem. Thanks to jazminschroeder and all contributors who helped make that a gem worth recreating for the Canada Post API

For more info see the Official Canada Post Developer Docs

Current implementation for the rates endpoint only, feel free to let me know if there are other services you would like to see included or make a PR

Installation

Add this line to your application's Gemfile:

gem 'canada-post-api'

And then execute:

$ bundle

Or install it yourself as:

$ gem install canada-post-api

Usage

Require the gem:

require 'canada_post'

Create a service:

canada_post_service = CanadaPost::Shipment.new( username: 'xxxx',
									password: 'xxxx',
									customer_number: 'xxxx',
									mode: 'development' )
# mode can be 'development' or 'production'

Define shipper:

shipper = { postal_code: 'M5X1B8',
			country_code: 'CA' }
# Post Code is required for US and CA shipments, not for International Shipments

Define recipient:

recipient = { postal_code: 'M5R1C6',
			  country_code: 'CA' }

Define package:

package = { weight: { value: 1, units: 'KG' },
            dimensions: { length: 25, width: 15, height: 10, units: 'CM' } }
# weight is the only requirement for your package, Canada Post only accepts KG and CM for the time being

To get service codes:

see Canada Post Rating API docs for service code descriptions

$ CanadaPost::Request::Rate::SERVICE_CODES
$ => ["DOM.RP", "DOM.EP", "DOM.XP", "DOM.XP.CERT", "DOM.PC.CERT", "DOM.PC", "DOM.DT", "DOM.LIB", "USA.EP", "USA.PW.ENV", "USA.PW.PAK", "USA.PW.PARCEL", "USA.SP.AIR", "USA.TP", "USA.TP.LVM", "USA.XP", "INT.XP", "INT.IP.AIR", "INT.IP.SURF", "INT.PW.ENV", "INT.PW.PAK", "INT.PW.PARCEL", "INT.SP.AIR", "INT.SP.SURF", "INT.TP"] 

Get Rates:

$ rates = canada_post_service.rate( shipper: shipper,
                                    recipient: recipient,
                                    package: package)

Not specifying a service type will return an array of all available rates

# complete response
$ [#<CanadaPost::Rate:0x007fd783f42a88 @service_type="Expedited Parcel", @service_code="DOM.EP", @total_net_charge="8.76", @total_base_charge="7.77", @gst_taxes="0.00", @pst_taxes="0.00", @hst_taxes="1.01", @transit_time="1">, #<CanadaPost::Rate:0x007fd783f42a60 @service_type="Priority", @service_code="DOM.PC", @total_net_charge="19.14", @total_base_charge="16.21", @gst_taxes="0.00", @pst_taxes="0.00", @hst_taxes="2.20", @transit_time="1">, #<CanadaPost::Rate:0x007fd783f42a10 @service_type="Regular Parcel", @service_code="DOM.RP", @total_net_charge="8.76", @total_base_charge="7.77", @gst_taxes="0.00", @pst_taxes="0.00", @hst_taxes="1.01", @transit_time="2">, #<CanadaPost::Rate:0x007fd783f429e8 @service_type="Xpresspost", @service_code="DOM.XP", @total_net_charge="11.31", @total_base_charge="9.58", @gst_taxes="0.00", @pst_taxes="0.00", @hst_taxes="1.30", @transit_time="1">] 

Specifying the service type will return one result

$ service_type = 'DOM.EP'
$ rates = canada_post_service.rate( shipper: shipper,
                                    recipient: recipient,
                                    package: package,
                                    service_type: service_type)
# complete response
$ [
	#<CanadaPost::Rate:0x007fd783fea238 
		@service_type="Expedited Parcel", 
		@service_code="DOM.EP", 
		@total_net_charge="8.76", 
		@total_base_charge="7.77", 
		@gst_taxes="0.00", 
		@pst_taxes="0.00", 
		@hst_taxes="1.01", 
		@transit_time="1">
  ]

Your final amount will be under total_net_charge:

$ rates.first.total_net_charge => '8.76' # all monetary values are CAD

This is still a work in progress but feel free to contribute if it will benefit you!
