+## Connections
+
+The `connection` property is a reference to environment configuration that contains name of an application setting containing a connection string. You can get this connection string by selecting the **Connection Information** button for the [namespace](../event-hubs/event-hubs-create.md#create-an-event-hubs-namespace). The connection string must be for an Event Hubs namespace, not the event hub itself.
+
+The connection string must have at least "read" permissions to activate the function. 
+
+This connection string should be stored in an application setting with a name matching the value specified by the `connection` property of the binding configuration.
+
+> [!NOTE]  
+> Identity-based connections aren't supported by the IoT Hub trigger. If you need to use managed identities end-to-end, you can instead use IoT Hub Routing to send data to an event hub you control. In that way, outbound routing can be authenticated with managed identity the event can be read [from that event hub using managed identity](functions-bindings-event-hubs-trigger.md?tabs=extensionv5#identity-based-connections).

 Use the function trigger to respond to an event sent to an event hub event stream. You must have read access to the underlying event hub to set up the trigger. When the function is triggered, the message passed to the function is typed as a string.
