How to integrate

When a consumer checks out, the amount to be paid by credit card is usually displayed without error and automatically on the payment terminal. For this to work, the cash register devices and the payment terminal must understand each other and be integrated.

PayXpert offers two integration modes with its PayXpress solution, thus initiating a payment efficiently. These integration modes are designed to simplify the process and offer a seamless experience to merchants and their customers.

It is important to note that all the APIs offered by these two integration modes work locally. This means that the PayXpress solution must be connected to the same local network as the external system/cash register. It is therefore essential that this local network has a stable Internet connection to ensure the proper functioning of the system.

Integration with the Caisse AP / Concert protocol

PayXpress is fully compatible with the Caisse AP protocol, recommended in France by the Association du Paiement (AP) to facilitate communication between cash registers and the PayXpress application. This protocol, also known as the Concert protocol, is supported by PayXpress in its version 3.2. For more technical information on this integration mode, please refer to Cash register integration.

App to App Integration - Android Intent

Another integration option offered by PayXpert is the App to App integration via Android Intent. This approach has the major advantage of allowing the point of sale or external system to integrate directly with the payment terminal. This functionality opens up new possibilities of use, including the transformation of the payment terminal into a full-fledged point of sale. Merchants can thus use the terminal to take orders at the table, in food trucks, or during street sales, among others, while ensuring a simple and efficient cashing process.

However, it should be noted that the Android application of the external system must be approved by the manufacturer of the payment terminal. For more technical information on this integration mode, please refer to App to app - Integration.
