Facebook Trigger

The Facebook Trigger starts a social workflow when a user comments on a Facebook Page post. Configure the post scope and optional keyword filters.

Two automations (comment vs later DMs)

Facebook comment flows and Facebook Messenger DMs are two separate workflows. One canvas has one trigger.

Comment bot — this trigger. Select Post can be one post or None (all posts). Then Messenger → Reply to Post, then Messenger → Private Reply to open the commenter's DM. This bot does not continue the private thread.
DM bot — a second automation with Pingmee Trigger, Platform facebookMessenger, When To Start Messages Created, then Messenger Direct Message nodes.

Do not put a Pingmee Trigger on the comment canvas. Facebook Trigger never starts on inbox DMs.

When to use

Comment automation on Page posts (replies, private replies, handoff).
Post-specific campaigns vs all comments on the Page.
Keyword filtering for contests or support intents.
