Access denied due to invalid subscription key (Face API)

Question

I am having trouble using Microsoft Face API. Below is my sample request:

curl -v -X POST "https://westus.api.cognitive.microsoft.com/face/v1.0/detect?returnFaceId=true&returnFaceLandmarks=false&returnFaceAttributes=age,gender" -H "Content-Type: application/json" -H "Ocp-Apim-Subscription-Key: 1xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxd" --data-ascii "{\"url\":\"http://www.mrbeantvseries.co.uk/bean3.jpg\"}"

I use the subscription id from my cognitive services account and I got below response:

{
  "error": {
    "code": "Unspecified",
    "message": "Access denied due to invalid subscription key. Make sure you are subscribed to an API you are trying to call and provide the right key."
  }
}

Not sure if I've missed out anything there. Can someone help me on this? Very much appreciated.

Answer 1

I ran into the same problem. I read the API documentation and it states the following.

You must use the same region in your REST API call as you used to obtain your subscription keys.

First, you must find the location of your subscription. In order to find the location of your subscription region, you must go to Cognitive Services -> Properties under the Label Location, you will find your subscription region. See below.

Second you must find the correct endpoint to make the call to. For example, if I want to make a call to the Computer Vision API, My location is East US, I will use either key 1 or 2, then I will use the following endpoint East US - https://eastus.api.cognitive.microsoft.com/face/v1.0/detect

You will now be able to have access to the API.

It appears that you've entered your Azure subscription ID instead? In the Azure portal, you can find the API key under 'Keys', shown below:

It will be a 32-digit hexadecimal number, no hyphens.
