Invalid API key
I requested, and was approved an API key for my class project. I tried plugging it into postman to mock a request, and it returns {"status_code": 7, "status_message :"Invalid API key..."}
What do I do? Should I request another key?

Take a test.
Click to go to your Profile > API: https://www.themoviedb.org/settings/api
At the bottom of the page, below, you'll find the Example API Request.
https://api.themoviedb.org/3/movie/550?api_key=THE_KEY
Use this example to do a search using your browser.
You will receive the basic data of the Movie Fight Club (1999)

If it works, your Key is OK.
If it does not work, let us know right here.

If the test worked correctly then the problem must be in your application programming.
Probably your API Request has a little error.
An extra space, a changed character, or something like that. This is common.
In order for us to help you, it is necessary that, if possible, you post here the Request that you are sending to the TMDb server.

Remember to replace your Key with THE_KEY , or something like that.
