fedex-web-services

Description

This gem provides an interface to the FedEx web services API. It supports version 12 of the ship service and version 13 of the rate service (the current versions as of November 2012). It interfaces with the FedEx web services SOAP API to look up shipping rates, generate labels, and cancel shipments (tracking coming soon).

Setup

Overview

This gem requires a large number of classes to communicate with FedEx. These classes are defined by the WSDL files for the FedEx web services API. For copyright reasons this gem does not include the files. You will need to create a FedEx developer account to download these files (this gem works with ShipService_v12.wsdl and RateService_v13.wsdl). I recommend putting them under your project's lib/ directory in lib/fedex/web_services/wsdl.

Creating the class definitions

Once you have the WSDL files, you will need to create the ruby classes used in the SOAP requests. This is a one time process that can be handled by the gem.

Rails

This gem includes a generator to create the class definitions and an initializer to load them if you are using it from within a Rails application. Simply save the FedEx wsdl files to a directory (lib/fedex/web_services/wsdl in this example) and include the gem in your Gemfile:

gem 'fedex-web-services', :require => 'fedex'

Then run the following generator:

$ rails g fedex:generate_definitions
Added /Users/brewski/nutsonline.com/git/kernelweb/lib/fedex/web_services/definitions
  create  config/initializers/fedex.rb

For more details, run the generator with the --help option:

$ rails g fedex:generate_definitions --help

Manual creation

You can also manually generate the class files. To to this, run the following command:

require 'fedex'
Fedex::WebServices::Definitions.generate_definitions('lib', *Dir.glob('lib/fedex/web_services/wsdl/*.wsdl'))

This will create the directory lib/fedex/web_services/definitions/ with the FedEx web services class definitions in it. After you have created the classes, simply include the following lines in your application to load them:

require 'fedex'
Fedex::WebServices::Definitions.load_definitions('lib')

Examples

Getting shipping rates

require 'fedex'
# config/initializers/fedex.rb handles this if you are in a Rails app and have run the generator above
# Fedex::WebServices::Definitions.load_definitions('lib')

include Fedex::WebServices
include Fedex::WebServices::Definitions

credentials = Service::Base::Credentials.new(
  "ACCOUNT#",
  "METER#",
  "AUTH_KEY",
  "SECURITY_CODE",
  :test
)

# prod_credentials = Service::Base::Credentials.new(
#   "ACCOUNT#",
#   "METER#",
#   "AUTH_KEY",
#   "SECURITY_CODE",
#   :production
# )

from = Address.new
from.postalCode  = "93401"
from.countryCode = "US"
from.residential = true

to = Address.new
to.postalCode  = "95630"
to.countryCode = "US"
to.residential = true

weight = Weight.new
weight.units = "LB"
weight.value = 42.42

rate_service = Service::Rate.new(credentials)
rate, response = rate_service.get_rates(
  ServiceType::FEDEX_2_DAY, RateRequestType::LIST, from, to, weight
)
puts "List rate for 42.42 lbs, 2 day from 93401 to 95630: #{rate.to_f}"

Creating a shipment with multiple packages

shipper = Party.new.tap do |shipper|
  shipper.contact = Contact.new.tap do |contact|
    contact.personName  = "Joe Shmoe"
    contact.phoneNumber = "(123) 456 789"
  end
  shipper.address = Address.new.tap do |address|
    address.streetLines         = [ "123 4th St" ]
    address.city                = "San Luis Obispo"
    address.stateOrProvinceCode = "CA"
    address.postalCode          = "93401"
    address.countryCode         = "US"
    address.residential         = true
  end
end

recipient = Party.new.tap do |recipient|
  recipient.contact = Contact.new.tap do |contact|
    contact.personName  = "Ahwahnee Hotel"
    contact.phoneNumber = "(801) 559-5000"
  end
  recipient.address = Address.new.tap do |address|
    address.streetLines         = [ "9006 Yosemite Lodge Drive" ]
    address.city                = "Yosemite National Park"
    address.stateOrProvinceCode = "CA"
    address.postalCode          = "95389"
    address.countryCode         = "US"
    address.residential         = true
  end
end

label_specification = LabelSpecification.new
label_specification.labelFormatType = LabelFormatType::COMMON2D
label_specification.imageType       = ShippingDocumentImageType::PDF
label_specification.labelStockType  = ShippingDocumentStockType::PAPER_LETTER

weights = [ 55.34, 10.2 ].map do |weight|
  Weight.new.tap do |w|
    w.units = "LB"
    w.value = weight
  end
end

ship_service = Service::Ship.new(credentials)

responses = ship_service.process_shipment(
  ServiceType::FEDEX_2_DAY, shipper, recipient, label_specification, weights
) do |request_contents|
  request_contents.requestedShipment.requestedPackageLineItems.each do |package_line_item|
    package_line_item.customerReferences = [
      CustomerReference.new.tap do |customer_reference|
        customer_reference.customerReferenceType = CustomerReferenceType::INVOICE_NUMBER
        customer_reference.value = "INVOICE 1234"
      end
    ]
  end
end

tracking_numbers = responses.map do |(tracking_number, label, charge)|
  puts "tracking number: #{tracking_number}"
  puts "charge: #{charge.to_f}"
  File.open("#{tracking_number}.pdf", "w") { |f| f << label }
  tracking_number
end

Canceling a shipment

tracking_numbers.each do |tracking_number|
  ship_service.delete_shipment(
    TrackingId.new.tap do |tracking_id|
      tracking_id.trackingNumber = tracking_number
      tracking_id.trackingIdType = TrackingIdType::EXPRESS
    end
  )
end

Debugging

You can see the SOAP wiredump by accessing Service::Base#wiredump after issuing a request.

begin
  rate, response = rate_service.get_rates(
    ServiceType::FEDEX_2_DAY, RateRequestType::LIST, from, to, weight
  )
rescue
  puts rate_service.wiredump
  raise $!
end
Something went wrong with that request. Please try again.
