Missing data
I'm tryna get list of popular movies but I can't see their genres in the data from the API

(https://api.themoviedb.org/3/movies/popular?api_key=<<api_key>>  

Also when I'm tryna data about a particular movie with its id, the production companies and production companies are empty.

https://api.themoviedb.org/3/movie/{movie_id}?api_key=<<api_key>>  

Your API Request for Popular contains an error.
There's an extra "S" in movie.

https://api.themoviedb.org/3/movies/popular?api_key=<<api_key>>
https://api.themoviedb.org/3/movie/popular?api_key=THE_KEY

As for the companies, make a test seeing the data of this film:

https://api.themoviedb.org/3/movie/550?api_key=THE_KEY  

And tell me if you can see the Companies in the answer.

Yea, I see them now but for the genres part does it show only the id? I thought it's meant to also show genre names for the popular movie API data

Yes, only the ID.
You need to do the conversion to text on your side.
Then you must have the list, in your language, of Genres and respective IDs.

Gender IDs:
