I have a Python application that uses a Facebook Business library. Therefore, I need to use a token provided by Facebook to access my insights and manipulate them.

However, this token has an expiration date, which is long, but I wanted to know if there is a way to update this token automatically within my application, so that it doesn't stop running.

My project is to post on Facebook using open ai generated content and I created a developers account along with a new Facebook account I need page access token and permissions but the only permissions allowed to me are email, public and payment permissions and I can't get access to page access token and I don't know how to set api endpoint here for redirect url.

I tried making the model that generates the caption but I can't put it here it shows error of not having the valid token

By current Google documentation

it's in the "TOOLS & SETTINGS > SETUP > API Center" but now "SETUP > API Center" is not there.

What is the current way to get a token or what page is the "API Center" currently on?
