Please document how to grab the computed ETag after updating the twin #20060

Closed uriel-kluk closed 3 years ago

[Enter feedback here] The UpdateDigitalTwinAsync returns an HTTP Response object, but it is not clear how to grab the computed ETag. The workaround is to do a new Read, but the extra trip is undesirable.

Hi @uriel-kluk you do not need to do a GetDigitalTwin after UpdateDigitalTwin in order to get the ETag. Within the Http headers of the Response object that UpdateDigitalTwin returns should be the new ETag for your digital twin after the update

timtay-microsoft commented 3 years ago

From the swagger, you can see that this ETag is returned for you:

"responses": {
  "204": {
    "description": "Success",
    "headers": {
      "ETag": {
        "description": "Weak Etag.",
        "type": "string"
      }
    }
  }
}
