I have created Cognitivenik Cognitive Services. And trying to access this api via postman request. I am getting 404 resource not found response . What the wrong with URL?
Once you know the service you need, you need to find the API url for it. In this example I will use the TextAnalytics Service for sentiment analysis.
The url to call this endpoint for you would be
https://cognitivenik.congnitiveservices.azure.com/text/analytics/v2.1/sentiment
Your headers look good so just updating the API Url, it should work for you.
