Before you start

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

GP tom application supports Android 8 and higher at the moment. Application requires NFC chip built in device and Internet connection via SIM card or Wi-Fi.

What you can do with API?

Through the API you can invoke a payment in the GP tom application, you can also cancel the payment through the API. For both in the response you receive transaction data that is used, for example, for receipts. Closing a batch can also be initiated through the API.
