What gives oauth 2.0 google?

Question

Google

I got the key manually and now I'm testing the Youtube v3 API, everything is fine, for example Get playlists by channel ID:

https://www.googleapis.com/youtube/v3/playlists?pa... I

request from the server, the response comes in the form JSON ...
I want to provide this to the user, will it be possible to do the same, but not with my key, but with his key, if he somehow passes authentication, I'm more interested in whether I can get his key to my server, can I also receive public data, How am I with mine now?

Answer 1

everything is possible
Google limits and rights - according to API Credenshils
, that is, there are no problems: from the 1st IP there are a lot of different ones, from different IPs a lot of different ones, from different IPs one, etc.
what is allowed by the key will get it
