Does my API key work?
Hi
I am getting error message 401 when I click "try it" on this page https://developers.themoviedb.org/3/movies/get-movie-credits
Does my API key work? Or is there anything I did wrong?
Thanks!

The "Try it!" option in DOCs it only works with the "Access Token Auth" option.
It doesn't work if you select the "API Key Auth" option.
Your API Key validation test is done using your Token.
https://developer.themoviedb.org/reference/authentication-validate-key
If your Token works then your API Key must also work.
If you want to test your API Key directly, follow the instructions below.

Take a Test
Using a computer, desktop or notebook.
On some mobile devices this test may not work correctly.
In the URL below, change THE_KEY to your API Key.
https://api.themoviedb.org/3/movie/550?api_key=THE_KEY
Use this example to do a search using a new tab or window in your browser.
You will receive the basic data of the Movie Fight Club (1999)
https://www.themoviedb.org/movie/550-fight-club
If it works, your Key is OK.

When there is a problem, the TMDb Server sends a message.
Can you tell which message the server sent?
Here is a list of possible messages:

If it does not work, let us know right here.

Thank you! The test for the token works and the API key also works for me.

Can I try my API key on the Credits page using this link "https://api.themoviedb.org/3/movie/movie_id/credits?language=en-US"? Do you know how can I do it? Thanks!

And when I open this page https://developer.themoviedb.org/reference/person-movie-credits, and click try it with my access token option, it gave me 404 error with { "success": false, "status_code": 34, "status_message": "The resource you requested could not be found." }

Sorry for the multiple questions!

Yes you can.
Just add after the question mark character, "?", your API Key followed by the ampersand character, "&".
Example:
api_key=12345678901234561234567890123456&

Your request for Movie ID 550 would look like this:

https://api.themoviedb.org/3/movie/550/credits?language=en-US
https://api.themoviedb.org/3/movie/550/credits?api_key=THE_KEY&language=en-US
https://api.themoviedb.org/3/movie/550/credits?api_key=12345678901234561234567890123456&language=en-US

You need to provide the ID of the Person you want film credits for.
For example, Tom Cruise
https://www.themoviedb.org/person/500-tom-cruise
Then enter 500 in the "person_id" field on the page.

An API Request to your browser would look like this:
https://api.themoviedb.org/3/person/500/movie_credits?api_key=THE_KEY&language=pt-BR

No problem. :-)

Thank you! That helps a lot!
