access token fanpage for dashboard

Question

I want to get access to my fanpage to show insights of the page on another website as a dashboard on a TV in our company.

1. How can I get a Access Token? I´ve already tried it in developer-facebook section. But I only get the Access Token for my personal profile.
2. Do the Access Token expire?

Answer 1

Facebook documentation already has a step-by-step tutorial for this.

Mainly, you need:

1. manage_pages permission
2. extend your user access token
3. get a page access token with the above user token (the generated page token will not expire)
4. You also need the read_insights permission for your specific case
