Introduction

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.

Please make sure that your implementation doesn’t throw an error if there are additional unknown parameters in structures.

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

We will test your implementation before any major change and if your implementation throws error on a new parameter then this limits us significantly.
