From install to payment

Four steps to a working integration.

The implementation model stays familiar across languages.

  1. 01

    Create a Payment Point

    Create an account and configure a service in the dpay dashboard.

  2. 02

    Get integration credentials

    Prepare the service name and Secret Hash; keep the secret on the backend only.

  3. 03

    Add the SDK

    Install the library for your language or start with the REST API.

  4. 04

    Handle payment and IPN

    Register a transaction, redirect the customer and update the order after a verified IPN.
