We have a IoTHub trigger function, which will be triggered when data will be received in IoT hub and it will push the data to Cosmos DB.
How we can use managed identity instead of connection string to connect to IoT Hub.
A Connection string must a constant variable, we are not able to add connection string at runtime. Please let me know can we resolve this?
[FunctionName("FunctionName")]
public async Task RunAsync([IoTHubTrigger("messages/events", Connection = "IoTHubConnectionString")] EventData message, [CosmosDB( databaseName: "%DatabaseName%", containerName: "%ContainerName%", Connection = "DBConnection")] IAsyncCollector<object> RawDataContainer, ILogger log)
Many of the native bindings in Azure Functions do not yet support Managed Identity.
If you require more flexibility, such as altering the connection string to target different azure endpoints, or using Managed Identity - then you shouldn't use Native bindings, instead leverage the appropriate SDK in your code.

Satyam Chauhan Alternatively, you can follow the doc: Connections and use IoT hub routing to send it to Event Hub and consume messages from Event Hub using Managed Identity.
