I have some js code that calls getMulti() with a query string, shows the first 3 results to the user, the user selects one and sends its TMDB id to the backend by means of a common HTML <form>. The backend receives the POST data with the TMDB ID and saves it for later use. Later, in a different webpage, the backend needs the full json of the previously selected result. Is there any API to get a movie/tv show/whatever getMulti returns, by its TMDB id?
