Instant private reply DM
Meta's Private Reply API delivers the DM seconds after the comment, as text, buttons, or a product card.
Public comment reply
Post a public "Check your DMs" alongside the private one, with variations for repeat commenters.
Built-in deduplication
Nobody gets the same automation's DM twice, however many times they comment.
Automatic contacts
Every commenter who triggers becomes a contact with tags and custom fields, ready for broadcasts.
Your agent sets up and tunes your comment-to-DM flows
496 tools on one OAuth connection. Nothing to install, nothing to self-host.
