Overview of protocols by terminal
Select a protocol:
app2app API
There is no better payment processing buddy for your phone or tablet app than our GP tom. It can talk to your app through the easy-to-integrate API interface and will send your app the payment result, your identifiers (invoice number, order number, purchase order, etc.) along with the receipt documentation - if you want to distribute it yourself.

Cloud API
Do you expect payments to be there anytime, anywhere for your systems and business? Then you've come to the right place. The unique cloud API is a publicly available interface through which your POS, your server, your cloud solution or even your website can initiate a payment. So now you have the possibility to initiate a payment on your mobile phone or terminal really from anywhere.

GPE prokol
By implementing this GPE protocol, it is possible to physically connect the cash register system (via RS232, USB, Ethernet or Wi-Fi depending on the type of terminal), or any other system with the Ingenico Telium2, Tetra or Nexgo payment terminals and their financial application. Instructions for several types of transactions can be given to the terminal and practically controlled for payment from an external system. Below you will find implementation documents for in-store terminals (desktop and mobile) and for self-service terminals.

ZVT protocol
This protocol is widespread in the DACH region (Germany, Austria and Switzerland) and requires a physical connection between the terminal and the cash register, usually via TCP/IP. This is a legacy protocol that requires more complex integration and testing, and certification is by appointment. we usually certify this protocol in Vienna. If you are doing a new integration to our systems, we recommend integrating the new API (app2app and Cloud API ) which will be developed in the future and offer support for all new features.

ECR2 protocol
The protocol formerly used by Slovak Savings Bank is offered for legacy platforms such as Verifony and is also available on Pax. It is not further developed, does not support the latest functionalities and is gradually being replaced by new API.
