Python AZ translate The request is not authorized because credentials are missing or invalid

Question

I am using Python 3.8.3 and try to use Azure Translation. Based on the example of (https://docs.microsoft.com/nl-nl/azure/cognitive-services/Translator/quickstart-translate?pivots=programming-language-python) I try to re-create the example for myself and minimized the code.

I create an Azure Resource (Translate) and copied the key and the endpoint in the code. But when I run the code, I get the following error:

"code": 401000,
"message": "The request is not authorized because credentials are missing or invalid."

Can someone please explain what i doing wrong and how to fix this issue!

I use this code:

import os, requests, uuid, json

path = '/translate?api-version=3.0'
params = '&to=de&to=it'
constructed_url = "https://api.cognitive.microsofttranslator.com" + path + params

headers = {
    'Ocp-Apim-Subscription-Key': 'xxxxxxxxxxxx',
    'Content-type': 'application/json',
    'X-ClientTraceId': str(uuid.uuid4())
}

# You can pass more than one object in body.
body = [{
    'text' : 'Hello World!'
}]
request = requests.post(constructed_url, headers=headers, json=body)
response = request.json()

print(json.dumps(response, sort_keys=True, indent=4, separators=(',', ': ')))

Many thanks Erik

Could the error be that there is a // in the url between the base-URL and path? — Hampus Larsson
What I mean is that it should maybe be this: "https://api.cognitive.microsofttranslator.com" + path + params It's a small change, but it would drastically change the path to the API. — Hampus Larsson
Thanks for the fast reply! It does not mather for the response.Have you other ideas ? — Erik hoeven
In the documentation you've linked it says this: If you are using a Cognitive Services multi-service subscription, you must also include the Ocp-Apim-Subscription-Region in your request parameters. If that's what you're using, then you might have to provide that in the headers variable as well. — Hampus Larsson
I use indeed "TextAnalytics", "Translator", "Cognitive Service" but what need i to fill in all the keys? — Erik hoeven

As per this doc, since you are using multiple services. It is a must to include the 2 authentication headers with your request.

Ocp-Apim-Subscription-Key   The value is the Azure secret key for your multi-service resource.

Ocp-Apim-Subscription-Region    The value is the region of the multi-service resource.

Location here is the specified Subscription Region.

Looking through your screenshot. It appears that region to be - westeurope

Updated Headers for your use case :

headers = {
    'Ocp-Apim-Subscription-Key': 'xxxxxxxxxxxx',
    'Ocp-Apim-Subscription-Region' : 'westeurope',
    'Content-type': 'application/json',
    'X-ClientTraceId': str(uuid.uuid4())
}
