Payment Collection

In this document, you’ll learn what a payment collection is and how to use it with the Cart Module.

What's a Payment Collection?

A payment collection stores payment details related to a resource, such as a cart or an order. It’s represented by the PaymentCollection data model.

Every purchase or request for payment starts with a payment collection. The collection holds details necessary to complete the payment, including:

  • The payment sessions that represents the payment amount to authorize.
  • The payments that are created when a payment session is authorized. They can be captured and refunded.
  • The payment providers that handle the processing of each payment session, including the authorization, capture, and refund.

Usage with the Cart Module

The Cart Module provides cart management features. However, it doesn’t provide any features related to accepting payment.

With the Payment Module, you can create a payment collection for the cart and handle the payment functionalities.

The Medusa application creates a link between the PaymentCollection and Cart data models. It also implements the payment flow during checkout as explained in this documentation.

Multiple Payments

The payment collection supports multiple payment sessions and payments. You can use this to accept payments in increments or split payments across payment providers.
