Create a payment app

Payment apps let approved payment providers integrate payment methods with Shoplazza checkout. This guide explains how to create a payment app, configure the payment session, process payments and refunds, and notify Shoplazza of transaction results.

What you can build​

With a payment app, a provider can support:

  • Redirect payments where the customer completes payment on a third-party payment page.
  • Iframe payments where a payment window is embedded in Shoplazza checkout.
  • Direct credit card payments on the checkout page.
  • Refund processing for completed payments.
  • Synchronous and asynchronous payment or refund result notifications.
