How to choose and implement an authentication method when working with Google Drive using PHP?

Question

Google

The main task is to extract files with the '.gsheet' extension from the Google drive, parse and pour them into the database.
The problem is that when mounting Google Drive to the Windows operating system, they look like links and weigh 1 kb.
Therefore, I decided to use the API, because I see no other way to implement this task (I don’t really want to parse the page that lies at the other end of '.gsheet'). But it requires afluorization, which has several types of Key, OAuth 2.0. Each of which has its own restrictions on the resources used. The examples from Google show how to implement applications that work with the data of customers who have come to your resource, but I don’t know how to do it with my own.

Answer 1

You can do it without the API, it's just that each document has its own key, so it seems better to use it
