like above this Azure portal how to get via api? Message receiving cloud to device.
Is your question about sending a message to a device by API or receiving?
Thank you for your response @Matthijs van der Veer. We are trying to send a message using api to the device. Is it possible? What are the other ways to send message to a device? Thank you.
Thank you Surbhi and Matthijs. The .Net sdk sample is working. I use a Avnet starter kit device. How can I receive the c2d message from my device. Is there any sample available for it? Thank you.
Probably best to make that a separate question, that way you can add more details and leave this one for people with the same need.
You can send Cloud-to-Device messages through the various SDK's. You can check a .NET example here
This SDK is also available in Python, Node.js, Java and iOS.
There does not seem to be a REST API to do the same, so the SDK is the way to go.

The formatting of your answer seems to be broken and I don't know how to fix it (I think it's the new Q&A version). I hope you don't mind I added a new answer instead.

This is insane! What type of an IoT platform does not allow a user to send a command to an IoT device??
@Innov8 thanks for the response on this thread.
What is your scenario or use case? for C2D messaging? we would be happy to help!
