I could not get my user page access token. I have enabled manage_pages in permission of my application settings.
When i access the Graph API I got blank data, no access token.
/page_id?fields=access_token
I am having the understanding that we can get user page access token by configuring manage_page permissions.

At the moment, I am trying to download dark posts from the /{user-id}/promotable_posts edge. From the documentation, I can download them using a user token with the ads_management permission or with a page access token.
I am able to check for the permission using the /debug_token node, but I need a way to determine if an access token is a page access token using code/api calls.
Thanks
You can do it by GET https://graph.facebook.com/v2.7/debug_token?input_token={access_token}&access_token={access_token}. If it is a page, response will contains profile_id which is the page id
I made a system user and he has permissions of manage_pages.
Then from his access token I made a call to this URL
me/accounts
Then the pages were listed below with their access tokens.
Then those access tokens didn't have manage_pages permission.
Problem:
I need manage_pages permission on those page access tokens.
I need to send private replies to page comments from my website. I am admin of the page and app.
Facebook's graph's api doc states following: "A Page access token with the read_page_mailboxes permission is required to create a message" but does not say, how to get the token with such permission.
I have tried tokens from "me/accounts", "/{page_id}?fields=access_token" and even generated 60 day access token from graph api explorer, but I get "OAuthException" with message "Requires read_page_mailboxes permission to manage the object". Any ideas?
To get a permanent Page Access Token with the additional permission 'read_page_mailboxes' you have to:
Generate a User Access Token with the permission 'read_page_mailboxes' for your app (use the Graph API Explorer) -> this generates a 24h User Access Token
Extend this User Access Token to "expires never" (using the Access Token Debugger)
Get a permanent Page Access Token with this User Access Token (using the Graph API Explorer on your Page Id)

facebook: permanent Page Access Token?
Note: You don't need to request this permission through developers.facebook.com/apps - "App Review" - "Submission" - "Add Items"
You need to ask the user for that permission during login, of course – like with any other permission.
It is the user (page admin), that grants this permission. Only after that is done, the page access token will “include” that permission.
Having an application token, a user who authorized the application with manage_pages permission, how can I access to the pages this particular user is admin of?
You can't, you need a user access token for that permission as outlined in the docs
https://developers.facebook.com/docs/reference/api/user/ (look for accounts)
You don t need an application token but a user access token to access those pages
i need to extend my facebook access token, I'm calling this:
https://graph.facebook.com/oauth/access_token?
client_id={MY PAGE ID}&
client_secret={THE SECRET KEY OF MY APP}&
grant_type=fb_exchange_token&
fb_exchange_token={AN ACCESS TOKEN FOR MY PAGE}
and I'm getting this error:
"error": {
"message": "Error validating application. Cannot get application info due to a system error.",
"type": "OAuthException",
"code": 101
}
I've seen a lot of problem with that access_token, but none answer relative to pages, idk why facebook use api that why... but is the way...
Thank you,
To get a long-lived access token you need to follow those steps:
Create an Application
Create a Page (your account need to be "administrator" of the page)
Associate the application to the Page (the same way you do it when you want to add a Page Tab to a Page)
http://facebook.com/add.php?api_key=*YOUR_APP_ID*&pages=1&page=*YOUR_PAGE_ID*
Get a short-lived access token with the permission "manage_pages" associated to your Application.
https://graph.facebook.com/oauth/authorize?client_id=__APP_ID__&scope=manage_pages&redirect_uri=http://www.facebook.com/connect/login_success.html
then
https://graph.facebook.com/oauth/access_token?client_id=__APP_ID__&redirect_uri=http://www.facebook.com/connect/login_success.html&client_secret=__APP_SECRET__&code=__CODE_FROM_PREVIOUS_REQUEST__
Using the Graph API Explorer with the request /me/accounts you can see the access tokens for each Pages that you are administrator. The problem is that those access token are short-lived.
Convert your short-lived access token to a long-lived (extending access token):
https://graph.facebook.com/oauth/access_token?client_id=_APP_ID_&client_secret=_APP_SECRET_&grant_type=fb_exchange_token&fb_exchange_token=_ACCESS_TOKEN_ON_STEP_4_
You can now test your new access token with the Access Token Debugger.
Scenario 5: Page Access Tokens
When a user grants an app the manage_pages permission, the app is able
to obtain page access tokens for pages that the user administers by
querying the [User ID]/accounts Graph API endpoint. With the migration
enabled, when using a short-lived user access token to query this
endpoint, the page access tokens obtained are short-lived as well.
Exchange the short-lived user access token for a long-lived access
token using the endpoint and steps explained earlier. By using a
long-lived user access token, querying the [User ID]/accounts endpoint
will now provide page access tokens that do not expire for pages that
a user manages. This will also apply when querying with a non-expiring
user access token obtained through the deprecated offline_access
permission.
