Build a payment app

Connect a payment provider to Tringify checkout without sharing merchant credentials.

A payment app connects Tringify checkout to a payment provider. Your app securely creates the provider payment, presents the provider-owned payment experience, and confirms the final result.

Before you begin#

You need a Standard app, an HTTPS service, a development store, and test credentials from the payment provider. Keep all provider credentials in your app; do not place them in Tringify settings or return them from an endpoint.

Build the integration#

  1. Choose the operations and currencies your app supports.
  2. Add a connection check so Tringify can confirm each merchant account is ready.
  3. Accept signed payment requests and return a secure payment experience.
  4. Confirm payment results through the Store API.
  5. Exercise successful, failed, pending, repeated, and expired payment attempts.
  6. Submit the completed declaration for review.
