So I am having a headache here on this API call. It definitely works correctly from Postman itself and gives me the right result. Which means that my API key is correct.

However, I tried to build my call myself from React first, however, it didn't work at all. Then I tried it with the code which Postman gave me as you can see on the right of the screenshot. However, also if I use that code, it still doesn't work. Also tested the "JavaScript fetch()" code from Postman in an individual file. Still no result. It keeps telling me that the API key isn't valid, but it's the same API Key, so it should just work fine.

Also, it doesn't matter if I use the Cookie or not. If I leave it out of the code, it still doesn't work. ( Ofcourse I masked the API KEY itself in the screenshot's code... )

Do I miss something here?
