Simple question : how do I set a cookie or get bearer token for the googleapis.com domain name ?
I’m meaning there’re many tutorials in how to log‑in the current user being logged‑in on Google, but they all work using a local app.
In my case, I need to send data to the googleapis.com domain name using Oauth for my current user but through his web browser. I know this is possible because although deprecated, that stuff still works for doing it and even might seem to be able to read the answer using javascript from cross‑origin without preflight. I see it works but I don’t understand how.
