publish_pages<\/code> from the Extended Permissions tab. Facebook will prompt for confirmation.<\/li>\n<\/ul>\nCopy the token; it’s the short-lived access token with the proper permissions for posting to your page. It’s a pretty long string.<\/p>\n
Make a long-lived access token out of the short-lived token. It’s required to create the never-expiring page access token. In the browser that’s logged in to Facebook as app admin, run this script (upload it to your server first…):<\/p>\n
<?php\ndefine('FACEBOOK_SDK_V4_SRC_DIR', '\/PATH\/TO\/fb\/src\/Facebook\/'); \nrequire 'fb\/autoload.php'; \nuse Facebook\\FacebookSession; \nuse Facebook\\GraphUser;\nuse Facebook\\FacebookSDKException;\n\n\/\/ grab your app's APP_ID and APP_SECRET from the developer dashboard \nFacebookSession::setDefaultApplication('YOUR_APP_ID', 'YOUR_APP_SECRET');\n\n\/\/ create a FacebookSession with the short-lived access token \n$session = new FacebookSession('SHORT-LIVED_ACCESS_TOKEN');\n\n\/\/ Get the AccessToken entity. \n$accessToken = $session->getAccessToken();\n\ntry { \/\/ get a long-lived token from the short-lived one \n echo $longLivedAccessToken = $accessToken->extend(); \n} catch(FacebookSDKException $e) { \n echo 'Error extending the short-lived access token: ' . $e->getMessage(); \n exit; \n}\n<\/code><\/pre>\nCopy the long-lived access token.<\/p>\n
To create a never-expiring page access token, run this script. It will list all Facebook pages that you administer, with their names, IDs and access tokens:<\/p>\n
<?php\ndefine('FACEBOOK_SDK_V4_SRC_DIR', '\/PATH\/TO\/fb\/src\/Facebook\/'); \nrequire 'fb\/autoload.php'; \nuse Facebook\\FacebookSession; \nuse Facebook\\GraphUser;\nuse Facebook\\FacebookRequest; \nuse Facebook\\FacebookRequestException; \n\nFacebookSession::setDefaultApplication('YOUR_APP_ID', 'YOUR_APP_SECRET');\n\n\/\/ create a FacebookSession with the long-lived access token \n$session = new FacebookSession('LONG-LIVED_ACCESS_TOKEN');\n\ntry {\n \/\/ Get a list of pages with you as admin\n $request = new FacebookRequest($session, 'GET', '\/me\/accounts?fields=name,access_token');\n $pageList = $request->execute()->getGraphObject()->asArray();\n foreach ($pageList as $page) {\n print_r($page);\n }\n} catch (FacebookRequestException $e) {\n echo 'Request error: ' . $e->getMessage();\n exit;\n}\n<\/code><\/pre>\nCopy the access_token<\/code> of the proper page. It’s the never-expiring page access token. Also copy the page’s ID, if you didn’t already have it. It’s a long number.<\/p>\nPaste the token into Facebook’s Access Token Debugger to check. ‘Expires’ should say ‘Never’, ‘Valid’ should be ‘True’, and ‘Scopes’ should include ‘manage_pages, publish_pages, public_profile’.<\/p>\n
Post to Facebook page<\/h2>\n
Fairly easy, given we now have the proper token.<\/p>\n

While the app is in development mode, which it is by default, the postings are only visible to you. In the app’s dashboard, set the app to Public in the Status & Review tab.<\/p>\n","protected":false},"excerpt":{"rendered":"
