Hermod REST API use cases

The table below shows some common use cases with corresponding commands, callbacks, and links to examples.

You can try out the use cases in the Hermod test client

Hermod REST API callbacks

Hermod sends callbacks to the integrators for command responses and timeouts. The integrator needs to implement a REST API to receive the callbacks from Hermod, according to Hermod API.

One callback URL must be registered for each API user (read X-Api-Key) and callbacks are sent to the API user that initiated the request. For more information, see Add API user and callback URL in Hermod
