Answer 1

The & symbol should be replaced with ? (question mark). Then it should work.

ex:

https://graph.facebook.com/oauth/access_token?grant_type=fb_exchange_token&client_id={app-id}&client_secret={app-secret}&fb_exchange_token={short-lived-token}

Answer 2

You get your page access token when you (the admin user) authenticate. The page token is based on your short-lived user token. In order to get a long-lived page token you need to get a long-lived user token. They usually last around two months.

Here's how you get a long-lived page token.

1. Get a short-lived user token.
2. Get your app ID and app secret.
3. Make the following GET call: https://graph.facebook.com/oauth/access_token&grant_type=fb_exchange_token&client_id={app-id}&client_secret={app-secret}&fb_exchange_token={short-lived-token}.
4. Now use the token returned from step 3 to create a new long-lived page token.
