I am using passport-facebook to obtain an access token. According to here
https://developers.facebook.com/docs/marketing-apis#access-token
under "Get Access Token", I should be getting a 60 day long-lived token. This is the case if the scope is only ads_read. However, when I add additional scopes of manage_pages and read_insights, there is no expiration when I check via the Graph API.
This seems to be a bit contradictory to me. My theory is based on the getting an API key with ads_read permission manually from the below tool.
https://developers.facebook.com/apps//marketing-api/tools/
Using this tool and debugging it via the Graph API, I see one difference in that it the manually generated access token has the "Page" row under it, indicating that it is a page access token (to my own pages). Since it is a PAT, it will never expire, as expected.
My passport-facebook generated access token has the ads_read, manage_pages, read_insights permission as well and the expiration says "Never Expires". However, it does not have the Page row on it. Does that mean I can still use it forever to query the ads insights API?
This is my attempt at obtaining a non-expiring Marketing API access token.
