Due to the increasing restrictions that Facebook has placed on the usage of its public API, we removed the ability to post to Facebook via Act-On's Social Publish feature on November 6th, 2019. 

There are several alternatives for creating social posts with Act-On:

• Use Act-On's Advanced Social Media Module, which includes additional functionality such as social listening and internal employee advocacy. Learn more here.
• Continue to use the Social Publish tool in Act-On to post to the other integrated platforms, LinkedIn and Twitter.
• Use another social publishing tool such as Hootsuite – these are not natively integrated, but you may be able to pass some data to/from Act-On using Zapier.

For an overview of Act-On's social media functionality, see this page.
