Retrieve device id from Service Bus Message in Azure Functions

Question

Is it possible to retrieve the deviceId from the Service Bus Message in the Azure Function? I am currently using ServiceBusReceivedMessage.

Here is the message route:

1. Device sends message to Iothub
2. Iothub routes the message to the Service Bus Queue
3. 2 triggers the Service Bus Triggered Function app listening to the queue.

Is it possible to retrieve the device id that sent the message to the Iothub in this case?

Answer 1

Can you check an ApplicationProperties of the received message?

It should be there, "iothub-connection-device-id".

In the case if ApplicationProperties collection is null/empty, see here.
