Register a Diagnostics Callback Listener URL:

`POST /callbacks`

You can register a URL endpoint at which an account will receive callback messages containing Live Streamed RF data for an IOT device from the Diagnostics Service. To receive these callbacks you have to set up a device Diagnostics observation using Start Diagnostics Observation.

The callback messages will be REST messages POSTed to the target URLs. You are responsible for creating and running a listening process on your server at those URLs to receive and parse the messages.

Diagnostics observation callbacks will be issued at the frequency and duration requested in Start Diagnostics Observation.

Uses and Requirements

Callback messages are secured with a shared secret key and SHA256 HMAC signatures. The response to this request (to register a callback listener) will contain the secret key in the header, and you must save the shared key to be able to authenticate and validate callback messages.
