Azure IoT Hub InvalidProtocolVersion

it seems like I have to get something really wrong on the Azure IoT Hub. I want to send a basic rest request to try testing it out.

I used postman for it and I already generated the SAS Token.

Postman

My URI is "https://xxxxx.azure-devices.net/devices/xxxxx/messages/api-version=2021-04-18". The first question would be where do I find my API-version? I saw that part in many other posts yet I don´t know where to find the information. So I just decided to fill in the date where I created the instances.

My Second Question would be how should I classify the SAS Token in the header? Is Authentification the right parameter?

Thanks a lot for the help.

You can find the answers to your question in this section of the docs.

  • Replace {api-version} with "2018-06-30" in the URI.
  • Set the Authorization header to a SAS token created as specified in the security tokens section of Using IoT Hub security tokens.

How did you create the SAS Token? Ensure to set right policy when generating the SAS token as well as an expiry time in the future, see https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-devguide-security#security-tokens

Azure CLI IoT generated tokens have a default validity of 1 hour and validity can be extended by the --duration parameter.
