Firstdata

Lightweight ruby bindings for the Firstdata 'Global Gateway e4' API.

Note: This works for v12+ of the API. It calculates the HMAC hash according to this (https://support.payeezy.com/hc/en-us/articles/203731149-API-Security-HMAC-Hash)

Installation

Add this line to your application's Gemfile:

gem 'firstdata'

And then execute:

$ bundle

Or install it yourself as:

$ gem install firstdata

Usage

Note: It is recommended that you use environment variables to set these values.

To set the keys:

 Firstdata.gateway_id = # gateway id goes here
 Firstdata.password = # password goes here
 Firstdata.key_id = # key id goes here
 Firstdata.key = # key goes here

To make a transaction:

 Firstdata.transact(
    # request hash goes here.
 )

For more information on what to put in the request hash, refer to the API reference guide or scroll down for examples.
