need some help - API Key dont work - general difficulti to find a guideline for beginners for handling requests
code/key problem solved .... chatgbt helps..... :-)
In addition, the structure of the website regarding API usage unfortunately looks quite different than in the video course I am currently attending and I am not yet a professional, a lot of things here are not understandable and self-explanatory for me.
links to guidelines that explain the basics of API requests for Move database data step by step would be helpful for me.
Is there something like this here or externally?

You've probably already browsed the DOCs.
But, in case of doubt, I'll post the link here.

To use the API v3

To use the API v4 (TOKEN)

Thanks ticao2, Of course, I've already discovered these links and read up on them, but I quickly come to the next question marks. What I am looking for is probably something that is not the purpose of this page, namely more basic knowledge about APIs in general and the handling of different request methods. If I know this better, I will also understand the get started pages here better, I think. Unfortunately, I am currently doing a course that also works with this API here but only very sporadically deals with the page itself and in the videos there is also an outdated user interface. So if anyone here can recommend youtube videos or other online sources that make working with the API up to date understandable for beginners, please share them here. 1000 thanks!
