Accepting iDEAL, Bancontact, SOFORT Banking, Creditcard, SEPA Bank transfer, SEPA Direct debit, PayPal, KBC/CBC Payment Button, Belfius Direct Net, paysafecard, ING Home’Pay, Gift cards, EPS, Giropay and Apple Pay 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.
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.
By far the easiest way to install the Mollie API client is to install it with gem. Note: v4.8.0 and higher are not published on rubygems.org, see GH-140 for details.
# Gemfile
gem "mollie-api-ruby", github: "mollie/mollie-api-ruby", tag: "v4.11.0"
$ gem install mollie-api-ruby
You may also git checkout or download all the files, and include the Mollie API client manually.
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.
Require the Mollie API Client. Not required when used with a Gemfile
require 'mollie-api-ruby'
Create an initializer and add the following line:
Mollie::Client.configure do |config|
config.api_key = '<your-api-key>'
# Timeouts (default - 60)
# config.open_timeout = 60
# config.read_timeout = 60
end
You can also include the API Key in each request you make, for instance if you are using the Connect API:
Mollie::Payment.get('pay-id', api_key: '<your-api-key>')
If you need to do multiple calls with the same API Key, use the following helper:
Mollie::Client.with_api_key('<your-api-key>') do
mandates = Mollie::Customer::Mandate.all(customer_id: params[:customer_id])
if mandates.any?
payment = Mollie::Payment.create(
amount: { value: '10.00', currency: 'EUR' },
description: 'My first API payment',
redirect_url: 'https://webshop.example.org/order/12345/',
webhook_url: 'https://webshop.example.org/mollie-webhook/'
)
end
end
payment = Mollie::Payment.create(
amount: { value: '10.00', currency: 'EUR' },
description: 'My first API payment',
redirect_url: 'https://webshop.example.org/order/12345/',
webhook_url: 'https://webshop.example.org/mollie-webhook/'
)
Note: If you specify an amount
, you must specify the correct number of decimals.
We strongly recommend sending value
as a string. Note that even though most currencies
use two decimals, some use three or none, like JPY
. All amounts returned in the v2
API will use this format.
payment = Mollie::Payment.get(payment.id)
if payment.paid?
puts 'Payment received.'
end
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 certain payment methods.
payment = Mollie::Payment.get(payment.id)
refund = payment.refund!(amount: { value: '10.00', currency: 'EUR' })
Fetching all objects of a resource can be convenient. At the same time, returning too many objects at once can be unpractical from a performance perspective. Doing so might be too much work for the Mollie API to generate, or for your website to process. The maximum number of objects returned is 250.
For this reason the Mollie API only returns a subset of the requested set of objects. In other words, the Mollie API chops the result of a certain API method call into pages you’re able to programmatically scroll through.
payments = Mollie::Payment.all
payments.next
payments.previous
