cant use api
When I use my API, it said couldn't be authenticated with those credentials

Does this happen to you using the "Try it!" feature in Docs?
For example: https://developer.themoviedb.org/reference/discover-movie

Good day, I have been unable to use the API key that was assigned to me since I registered on the website. When I try to use the API in the website's API Reference page, it returns an error message that says: { "status_code": 7, "status_message": "Invalid API key: You must be granted a valid key.", "success": false } The Access Token displays some results when I change my options to it. What I really need is the API key. How can this be fixed?
