These pages describe the communication protocol between your POS system and Qerko servers. The other actors appearing in this document are the restaurant which has your POS system installed and the customer using the Qerko app in the restaurant.

The communication uses the HTTPS protocol to query a REST API. The data is transferred in JSON format. You can use HTTP Long-Polling or websocket for communication.

Recomended flow of integrating:

  • Start with implementing table list
  • Continue with table contents
  • Finish the base flow with payments and if wanted, continue with orders.

We wish you as easy integration as possible. You can contact us at to request technical support.
