What's an example request that you're making that isn't working like you expect?

$movie_url = 'https://api.themoviedb.org/3/movie/44217/translations?api_key=MyAPI_KEY'; In this exemple i want the translation for vikings in french and the translation isn't available only 5 languages are available :/ and on the database website the description is in french how did you get it ?

I'm going to assume you're actually looking for the TV show Vikings, is that right? If so, you need to make a call to the TV endpoints, not movie. The id 44217 you are calling above is for the movie Jasmine Woman.

https://api.themoviedb.org/3/tv/44217/translations?api_key=###

Or better yet, with append_to_response:

https://api.themoviedb.org/3/tv/44217?api_key=###&append_to_response=translations

Thank's for the tips ( about append_to_response ) but i didn't see the translation in french :( . Should I put a translation=fr ? or something ?

Did you update your request URL to the TV method? The call you were making above is to the movie, not the TV show.

And the response, which I've truncated but as you can see French is there:

  "id": 44217,
  "translations": [

      "iso_3166_1": "FR",

      "name": "Français",

        "homepage": ""
      }
    },
