Mollie API client for Ruby

Accepting iDEAL, Bancontact/Mister Cash, SOFORT Banking, Creditcard, SEPA Bank transfer, SEPA Direct debit, Bitcoin, PayPal, Belfius Direct Net and paysafecard online payments without fixed monthly costs or any punishing registration procedures. Just use the Mollie API to receive payments directly on your website or easily refund transactions to your customers.

Requirements

To use the Mollie API client, the following things are required:

Get yourself a free Mollie account. No sign up costs.
Create a new Website profile to generate API keys (live and test mode) and setup your webhook.
Now you're ready to use the Mollie API client in test mode.
In order to accept payments in live mode, payment methods must be activated in your account. Follow a few of steps, and let us handle the rest.
This API client requires the REST Client and JSON gems.

Installation

By far the easiest way to install the Mollie API client is to install it with gem.

$ gem install mollie-api-ruby

You may also git checkout or download all the files, and include the Mollie API client manually.

How to receive payments

To successfully receive a payment, these steps should be implemented:

Use the Mollie API client to create a payment with the requested amount, description and optionally, a payment method. It is important to specify a unique redirect URL where the customer is supposed to return to after the payment is completed.
Immediately after the payment is completed, our platform will send an asynchronous request to the configured webhook to allow the payment details to be retrieved, so you know when exactly to start processing the customer's order.
The customer returns, and should be satisfied to see that the order was paid and is now being processed.

Getting started

Requiring the Mollie API Client.

require 'Mollie/API/Client'

Initializing the Mollie API client, and setting your API key.

mollie = Mollie::API::Client.new
mollie.api_key = 'test_dHar4XY7LxsDOtmnkVtjNVWXLSlXsM'

Creating a new payment.

payment = mollie.payments.create(
  amount: 10.00,
  description: 'My first API payment',
  redirectUrl: 'https://webshop.example.org/order/12345/'
)

Retrieving a payment.

payment = mollie.payments.get(payment.id)

if payment.paid?
  puts 'Payment received.'
end

Refunding payments

The API also supports refunding payments. Note that there is no confirmation and that all refunds are immediate and definitive. Refunds are only supported for iDEAL, credit card and Bank Transfer payments. Other types of payments cannot be refunded through our API at the moment.

payment = mollie.payments.get(payment.id)
refund  = mollie.payments_refunds.with(payment).create

Examples

The examples require Sinatra so you will need to install that gem first. Afterwards simply run:

$ cd mollie-api-ruby
$ ruby examples/app.rb
