REST API
Communication Protocol Between the Acceptance Devices App and POS System in Cloud
Mode
When operating in Cloud mode, the communication protocol used between the Acceptance
Devices app and the point-of-sale (POS) system is a single HTTPS request to the backend.
The response is sent synchronously. The POS system keeps the connection open until the
transaction is completed and the response is provided. The backend timeout setting is
180 seconds.
