Does westus.dev.cognitive.microsoft.com make real REST requests to my Face API resource or is it just a supporting page?

Question

Hello, I am starting to work with Face API for the development of an application that uses face identification. I have been reading the documentation offered by Microsoft, but the following is still not clear to me: does the Cognitive Services website already make real requests to my created Face resource or are they just test requests to understand how it works? I ask because I'm confused that it requests both my endpoint and the Azure subscription. Thank you very much for your answers!

The web page I am referring to is the following (official Azure documentation): https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395244

Hello @Valeria Margarita Espinoza Sanchez ,

Regarding API reference you specified, there are information about request/response on the page. They are just samples and the page does not interact with your instance.

On the other hand, if you choose one of regions to navigate yourself to the API interaction test page, requests from the page are passed to resource(s) specified with api-key (Ocp-Apim-Subscription-Key) or resource name. When you enter values related with your resource to the page, the web page make real requests to your resource(s).
