Google Drive Link URL Format and Request Parameters

Question

I am desperately trying to find where google docs and google docs schema and query parameters are documented. For example, which usp = parameter has several possible values? Also, why a link like this https://drive.google.com/drive/u/2/#folders/ will open a folder in Safari and Chrome without a new authentication, while a link like https: // drive. google.com/drive/#folders/ will only work correctly in chrome. What is the meaning of u / 2 /? etc. Does anyone know how to find the full documentation of these URL schemes?

Answer 1

Since the part about / u / 2 / has already been satisfactorily explained, I will try to explain the part about usp from my best understanding.

It seems that we are just providing data from where you got access to the document.

usp=docs_home- This is when you create a new document from the Google Docs themselves. usp=drivesdkit is set when you get the link using the SDK drive
usp=sharing- this is when you get the link from the sharing dialog
usp=drive_web- this is what you get when you click on the document on the main page of the Documents or in Drive it usp=direct_urlappears on the main page of the Documents when you go directly to sheets.google.comorslides.google.com
