0 - Open the token validator

Go to https://developers.facebook.com/tools/debug/accesstoken/ and use this page to test your tokens at each step, namely looking at their expiry date.

1 - Get a short-lived token

Go to developers.facebook.com and generate a User token with the permissions required.

To post to pages you need pages_show_list, pages_read_engagement, pages_manage_posts, public_profile.

This is {your-access-token}, the short live access token (1h).

2 - Get a long-term token from that (2 months)

curl -i -X GET "https://graph.facebook.com/{graph-api-version}/oauth/access_token?grant_type=fb_exchange_token&client_id={app-id}&client_secret={app-secret}&fb_exchange_token={your-access-token}"

# {graph-api-version} >= v10.0
# {app-id} = name of the app in https://developers.facebook.com/tools/explorer
# {app-secret} = secret from the app page > settings > basic > App Secret
# {your-access-token} = the User token from an account with admin permission for the facebook page

# returns your {long-lived-user-access-token} as access_token (2 months)

3 - Get your user id

https://graph.facebook.com/v2.10/me?access_token={access_token}

# access_token is your long term access token

# return your {user-id} 

4 - Get a non-expiring token

Take the token from the 2nd step and pass it as {long-lived-user-access-token}:

curl -i -X GET "https://graph.facebook.com/{graph-api-version}/{user-id}/accounts?access_token={long-lived-user-access-token}"

# {graph-api-version} >= v10.0
# {user-id} = id of the user (not of the app) from step 3
# {long-lived-user-access-token} = token from step 2

# returns a final data array with {access_token}

In my case, it's returning an empty data:

{"data":[]}

got the same result

This has not been tested in a while so may have changed on facebook's side, please share if you have an up-to-date guide.

sure, will do.

I just tested this and it still works for me.

Same here. Getting {"data":[]}

In step 3 I am getting a "Malformed access token" when using the token returned in step 2

code in step 3, Line 1 should read
curl -i -X GET "https://graph.facebook.com/v2.10/me?access_token={access_token}"

Looks like this is working and/or has been fixed. Thanks for this.

I know this post has been marked as resolved. I am getting the same empty data as users mentioned earlier. could there be an issue with Facebook. if anyone has any updated answers please share. Thanks.
I am getting {"data":[]}%

I just tried it and it works.
For me, running the query curl -i -X GET "https://graph.facebook.com/{graph-api-version}/{user-id}/accounts?access_token={long-lived-user-access-token}" returns a page token.
Interestingly, after this query, the previously used long-lived token is now marked as having an "expiration: never" in the facebook debug tool

is this also possible to get a long lived token to access facebook insights data?

It worked as charm for me today.

@msramalho Hi, is this also possible to get a long lived token to access facebook insights data?

I've not used it to look into those @janez33 but welcome any insight you may find!

Thanks @msramalho for sharing this. I have been searching for it for last 3 days.

I am using v19.0 and I am getting {"data":[]} executing the last step.

I am trying to access:

pages_show_list
pages_read_engagement

I am using v19.0 and I am getting {"data":[]} executing the last step.

I am trying to access:

pages_show_list
pages_read_engagement

Add business_management permission

Perhaps you should try it.

I managed to obtain a long-term token using the Facebook Lite + App Cloner APK
and until now, it's still working well...
