HTTP requests to Trello

Hi, I’m a an absolute noob at coding and I don’t have much of an idea. I want to use Trello as a whitelist system for some tools in a group however I have no idea how to do this, I tried an API tutorial but it was made in 2018 and I don’t think it works or I couldn’t anyway.

Basically, how do I ask trello to get a list and then get the names of the cars on the list?

Any help is appreciated
