Backend integration

General flow

The following diagram shows the different states of the order in the system and the API calls (or timeouts) that change the states. For explanation of the particular APIs, timeouts and response types, see the documentation below. There are multiple Order CANCELED states in the diagram, that is only for clarity (to keep the flow from top to bottom as much as possible and to avoid connecting all the arrows to a single state) and the states mean exactly the same.

Backend API calls diagram

The following diagram shows the happy path of the backend order flow with the synchronous version of Order accept API in the RH operator system, it ends with a successfully confirmed order. The auth section describes the phase of authenticating the frontend app, this needs to be done by the RH native app via Watchdog auth API before initialising the Mileus watchdog SDK.
