I'm trying to use the Discover API. I know my API-Key is valid since the following works:

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

But as soon as I start adding parameters, it fails ({"status_code":7,"status_message":"Invalid API key: You must be granted a valid key.","success":false}). When I use the "try it" with the parameters I really want to use, it works, but when I tried copying that URL and adjusting it to use my API-Key, I can't get it to work. For reference, the following are the parameters I really want to specify:

?include_adult=false ?include_video=false ?language=en-US ?primary_release_year=2023 ?with_genres=28|12|80|18|36|27|9648|878|53|10752 ?with_original_language=en

Here's the full URL as I built it with the parameters above:

https://api.themoviedb.org/3/discover/movie?api_key=?include_adult=false?include_video=false?language=en-US?page=1?primary_release_year=2023?with_genres=28|12|80|18|36|27|9648|878|53|10752?with_original_language=en

Can someone shed some light on this for please? I'm sure it's something simple that I'm just not used to (I'm a retired IT Nerd that spent a lot of years programming, but not in the web world). For example, are there mutually-exclusive parameters that I can't use together (I don't think so, but am obviously grasping) or are the parameters required to be specified in a specific sequence, etc?

Thanks, Mark
