How to use postman to test send data to iot central

Feiling Pan 40

I don't know how to operate, maybe it needs middleware or something else, I have tried to use function and so on as middleware delivery, but it doesn't seem to work. I wish someone could teach me step by step. I've been doing this for a long time.

Hi @Feiling Pan](/users/na/?userid=edb7c8f1-ba37-411d-b8ef-6ba0f1379ece) Greetings! Welcome to Microsoft Q&A forum. We would be glad to assist you with this request.

The IoT Central Device API provides different endpoints that enable us to update properties of a device on IoT Central. Please refer the following methods for reference.

Update Relationship Patch a given relationship given the relationship ID and a given device ID.

Update	Update a device via patch
Update Attestation	Update an individual device attestation via patch
Update Component Properties	Update device properties for a specific component via patch
Update Module Component Properties	Update module properties for a specific component via patch
Update Module Properties	Update module properties via patch
Update Properties	Update device properties via patch
Update Relationship	Patch a given relationship given the relationship ID and a given device ID.

Update Relationship Patch a given relationship given the relationship ID and a given device ID.

Have you tried using the Update properties method and to send data to IoT Central? The API needs a Bearer token for authentication which can be obtained executing the command az account get-access-token --resource https://apps.azureiotcentral.com from Azure shell.

Please note that it might be easier to simulate data using an SDK instead of postman. If you prefer to simulate data using a .Net SDK, please refer the post How to generate custom telemetry string data for a simulated device sensor in IoT Central where a solution to this has been shared.

Please let us know if you have any additional questions on this.

There are multiple guides and a sample Postman file that illustrate most of the IoT Central REST API here:

There's a link to download the Postman collection in each of these articles.

Thank you for your reply. Now I want to make a mobile app to send the Bluetooth data read to iot central. But these documents don't seem to have that capability.
