If you have more than one website and their facebook pages, management and sharing of these pages can be tedious and time consuming.

I have found a solution to this problem. I prepared the codes with the Postman.

Setup

• Instead of %PICTURE_URL% type the image address to be shared.
• Instead of %MESSAGE% write a post to share with picture .
• Instead of %FB_TOKEN%, type facebook access token.
• If you want to automate the tasks completely, you can add it to your cron jobs section of your hosting control panel after you have done the following by yourself:

/usr/bin/php -q /home/hostname/public_html/directory/file.php

Facebook Token Receiving

I skip creating a facebook application, assuming you already have a facebook app.

• Go to https://developers.facebook.com/tools/explorer/ and grab your token. If you are going to share on the page, be sure to give the publis_pages permission.
• Extend your token membership by visiting https://developers.facebook.com/tools/debug/accesstoken/. When the time is over, you will have to extend again.
