 The [Send telemetry from a device to an IoT hub](quickstart-send-telemetry-python.md) quickstart demonstrates the basic device-to-cloud messaging functionality of IoT Hub. However, in some scenarios you cannot easily map the data your devices send into the relatively small device-to-cloud messages that IoT Hub accepts. When you need to upland files from a device, you can still use the security and reliability of IoT Hub.

-    * **get_storage_info_for_blob** gets information from your IoT hub about the linked Storage Account you created previously. This includes the hostname, container name, blob name and a SAS token. This information is passed to the **store_blob** function (in the previous step), so the **BlobClient** in that function can authenticate with Azure storage. The **get_storage_info_for_blob** method also returns a correlation_id, which is used in the **notify_blob_upload_status** method.

It's used by IoT Hub to notify any service that might be listening for a notification on the status of the file upload task.
