dwolla-ruby

Official Ruby wrapper for Dwolla's API

Version

2.7.0

Requirements

• Ruby

Installation

The easiest way to install the dwolla-ruby gem for now is to use bundler and add the following line to your Gemfile:

gem 'dwolla-ruby'

The recommended way to install dwolla-ruby is through RubyGems:

gem install dwolla-ruby

Examples / Quickstart

To use the examples in the /examples folder, first edit the _keys.rb file and add your Dwolla API application's key, and secret, along with your account's OAuth token, and PIN.

This repo includes various usage examples, including:

• Authenticating with OAuth [oauth.rb]
• Fetching user information [users.rb]
• Grabbing a user's contacts [contacts.rb]
• Listing a user's funding sources [fundingSources.rb]
• Transacting money (includes sending) [transactions.rb]
• Getting a user's balance [balance.rb]

Concurrent requests

If making requests using any background processing library such as Sidkiq or Resque, we recommend that you manually pass in tokens to functions which take an OAuth token.

For example, we can do this with the Contacts class:

# Include the Dwolla gem
require 'rubygems'
require 'pp'
require 'dwolla'

Dwolla::Contacts.get(nil, "your_token")
