Does the IoT Hub Built-in Event Hub endpoint support access using Managed Identity similar to regular Event Hubs? Here is an example - https://learn.microsoft.com/en-us/azure/event-hubs/authenticate-managed-identity?tabs=latest.

    Hello @Raj Tiwari,

    welcome to this moderated Azure community forum.

    From as far I have seen (and the Azure Portal supports it) you need to use the 'connection string':

    You can however route messages TO and EventHub via the IoT Hub routing option:

    User's image

    There, you can use a managed Identity if the IoT Hub identity is activated:

    Check out Azure IoT Hub routing.

    Be aware the default event-hub-compatible endpoint turns into a fallback solution when routing is added.
