Using the Payment Gateway through the Payrexx API is the most customisable integration option.


Before you start developing you need a few things...
  • Payrexx account: Signup here
  • A fully set up payment provider which fits your needs: PSP Features
  • API credentials: Find them in your Payrexx account under API & Integration

Process - Gateway


First you have to choose one of the available payment types. This will be needed once you start building your Gateway
If you want to make one-time payments, you can skip this step. Because one-time is the default type.

Start Building

Finally! You can now start developing.
