Remit

This API provides access to the Amazon Flexible Payment Service (FPS). After trying to get the SOAP version of the API written, I began working on this REST version to provide a cohesive means of access to all of the functionality of the FPS without having to get dirty dealing with SOAP requests.

I hope you enjoy using it as much as I've enjoyed writing it. I'm interested to hear what sort of uses you find for it. If you find any bugs, let me know (or better yet, submit a patch).

Sandbox

Amazon provides a testing environment for the FPS called a sandbox. You may (and should) use the sandbox while testing your application. It can be enabled by passing a value of true to the last argument of the API constructor.

Getting Started

The following example shows how to load up the API, initialize the service, and make a simple call to get the tokens stored on the account:

gem 'remit'
require 'remit'

ACCESS_KEY = '<your AWS access key>'
SECRET_KEY = '<your AWS secret key>'

# connect using the API's sandbox mode
remit = Remit::API.new(ACCESS_KEY, SECRET_KEY, true)

response = remit.get_tokens
puts response.tokens.first.token_id

Using with Rails

To use Remit in a Rails application, you must first specify a dependency on the Remit gem in your config/environment.rb file:

config.gem 'remit', :version => '~> 0.0.1'

Then you should create an initializer to configure your Amazon keys. Create the file config/initializers/remit.rb with the following contents:

config_file = File.join(Rails.root, 'config', 'amazon_fps.yml')
config = YAML.load_file(config_file)[RAILS_ENV].symbolize_keys

FPS_ACCESS_KEY = config[:access_key]
FPS_SECRET_KEY = config[:secret_key]

Then create the YAML file config/amazon_fps.yml:

development: &sandbox
  access_key: <your sandbox access key>
  secret_key: <your sandbox secret key>

test:
  <<: *sandbox

production:
  access_key: <your access key>
  secret_key: <your secret key>

To instantiate and use the Remit API in your application, you could define a method in your ApplicationController like this:

def remit
  @remit ||= begin
    sandbox = !Rails.env.production?
    Remit::API.new(FPS_ACCESS_KEY, FPS_SECRET_KEY, sandbox)
  end
end
