Is it possible to make multiple requests within one authorization?

Question

Google

In the Google API, before the request, you need to do OAuth authorization.
And if, for example, I need to get the last unread email, then I need to first get a list of all emails, and then select the last one, and make a request to a specific email. Do I need to pass authorization before each request? What if I need to read the last 20 emails? Login 20 times?
I use Node

Answer 1

Once you receive an OAuth token, it can be used many times until it expires or is otherwise invalidated
