Paddle Billing Integration Guide

Paddle is a popular platform for selling software and other digital goods. Here's a step-by-step guide to help you integrate Paddle with Mixpost Enterprise and get started with processing payments.

1. Create an account

  • Production: If you haven’t already, visit Paddle's website and sign up for an account.
  • Sandbox (only for testing): If you haven’t already, visit Paddle's sandbox website and sign up for an account.
note

We recommend to use a Sandbox account first and testing the integration. If everything is fine, you can switch to a production Paddle account.

Before processing checkout payments using Paddle, you should define your application's default payment link in your Paddle checkout settings dashboard. We recommend setting the URL of the Mixpost instance.

  • Enter Description;

Replace <MIXPOST_CORE_PATH> with your specified MIXPOST_CORE_PATH. If you have not altered the MIXPOST_CORE_PATH environment variable, use the default value: mixpost.

Note: For the Lite package, use the value mixpost.
