Select an API method
Mollie has two APIs available for handling payments. You must apply one of them in the app so that it can create and process payments.
Payments API creates a simple payment for the full order amount. When you apply this API, you can issue (partial) refunds by amount.
Orders API creates an order that contains the customer's details and purchased products. Mollie automatically creates a payment based on the order. When you apply this API, you can issue (partial) refunds for order items and send partial shipments.
Note
in3 and Klarna payment methods always use Orders API. This means that when you select Payments API to handle payments, it applies to all payment methods except in3 and Klarna.
