Social managers watch the Facebook Page, but sales, support and the rest of the team rarely do. FlowMattic posts the Page activity they need to Slack: new posts to share, comments that need an answer, complaints for support and a heads-up when a live video starts. For brands, agencies and local businesses with an active Page.

1. TriggerNew Post in Page Feed2. ActionSend Channel MessageWhen Facebook Pages fires New Post in Page Feed, FlowMattic runs Send Channel Message in Slack with the data from that event.
You build this in the FlowMattic workflow builder on your own site. See the setup steps
Each one uses only triggers and actions the two integrations ship today, plus FlowMattic's own tools. Where the library has a ready-made template, import it instead of building from scratch.
Ready-made templateWhen the Page publishes, the team gets the text and link in Slack, so staff can like, comment and share it while the post is new.
New Post in Page FeedSend Channel Message
View the template Each comment on the Page arrives in Slack with the commenter's name and the post it belongs to, so whoever is free can answer it on Facebook.
New CommentSend Channel Message
A Filter looks for words such as refund, broken or late. Those comments go to a private support channel, which keeps unhappy customers from being left in public.
New CommentFilterSend Private Channel Message
The AI Agent reads the comment and the post, drafts a short reply in your brand voice and posts both to Slack, so the social manager edits instead of writing from scratch.

Going live posts a message with the link to the moderators' channel, so someone joins the stream to answer questions and hide spam from the start.
Live Video StartedSend Channel Message
A Page with several editors can lose posts by mistake. Each deletion sends admins a Slack message with the post ID and time so they can check what happened.

Each new video is posted to the content channel, where the team decides whether to cut it into a reel, story or blog embed.

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
Facebook Pages and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
Comments and post details travel from Facebook to Slack through your WordPress server rather than another company's automation account.
Runs are unlimited, so a Page with hundreds of comments a day posts each one without a larger plan.
Filters send complaints to support, live videos to moderators and new posts to everyone, instead of one noisy channel.
Start a workflow with the Facebook Pages New Comment trigger, choose your Page and add Slack Send Channel Message with the comment text, the commenter and a link to the post.
Not from Slack with these workflows, which only post there. You can keep it in one workflow instead: New Comment, an AI Agent draft, a Human in the Loop approval, then Reply to a Comment once someone approves it.
Yes. Build one workflow per Page, each posting to its own Slack channel, or to one shared channel with the Page name in the message.
New Reaction is a trigger, so you can post reactions to Slack. On a busy Page that is a lot of messages, so most teams filter for one reaction type or skip it.
