Each post is cleaned and prepared so important details like post ID, message, user name and time are easy to work with.\nThe post message is then sent to AI, which checks whether it violates group rules (such as spam, scams, hate, adult content or self-promotion).\n\nIf the post is safe, the workflow simply moves on to the next post.\nIf the AI flags a violation, the system alerts the moderation team and saves the details for tracking.\nFor high-severity violations, the workflow automatically hides the post on Facebook.\nFinally, the team is notified in Slack whether the post was hidden successfully or if manual action is needed.\n\nThis helps reduce manual moderation work and ensures fast responses to serious issues.\n\n## Setup steps\n\n**1.** Connect the Facebook Webhook to your group feed.\n\n**2.** Add a valid Facebook Page Access Token in environment variables.\n\n**3.** Configure OpenAI credentials for content moderation.\n\n**4.** Connect Slack for alerts and Airtable for logging.\n\n**5.** Test the workflow with sample Facebook posts.\n\n**6.** Activate the workflow."
