You can merge posts or events from multiple Facebook pages into one single feed by using our handy Multifeed Extension. Simply install the extension by following the directions on the How to Use tab on the extension page and define your Facebook Page IDs on the plugin’s Settings page. You can then select to only show Events by unchecking the other post types in the Post Types section of the Customize page.
As each events feed requires an Access Token for that specific Facebook page then you need to tell the plugin which Access Token is for which page, like so:
ID1:TOKEN1, ID2:TOKEN2, ID3:TOKEN3
Here’s an example of doing this in the shortcode:
[custom-facebook-feed type=events id=”page_id_1, page_id_2, page_id_3″ accesstoken=”page_id_1:access_token_1, page_id_2:access_token_2, page_id_3:access_token_3″]
