Before you start

If you are a developer of any merchant services solution, you can easily integrate with our solution via API. Using this API, you can easily initiate a card payment, which will launch our payment app. We will then return the payment result directly to your app and redirect the user. We also provide other methods and functionalities related to payments (cancellations, closing batches, transaction status and others).

The GP app currently supports Android 8 and above. The app requires a device with a built-in NFC chip and an internet connection via a SIM card or Wi-Fi.

Which integration methods do we currently support:

What can you do with the API?

You can use the API to initiate a payment in the GP tom application, and you can also use the API to cancel a payment. In both cases, the response contains transaction data that can be used, for example, for receipts. You can also use the API to initiate the closing of a batch.

In both cases, you will receive the receipt details so that you can create a financial receipt on your end. For more information, please visit this page.
