Public comment replies

Optionally reply on the comment thread so people know to check their Instagram inbox for the DM.

Updated Sep 14, 2026

Short answer: On a Post or Reel Comments trigger, the optional Reply Message field is posted as a public comment. Keep it short (‘Sent to your DMs 📬’). The private DM is a separate Send Message node. Live comments only allow a private reply — Instagram does not let apps answer live comments in public.

The public reply is a nudge, not the offer. Instagram lets your app comment back so the person knows a DM is waiting.

Set it

  1. Edit the Post or Reel Comments trigger.
  2. In Reply Message (Optional), write one short line.
  3. Save. That text is posted under their comment.
  4. The private content lives on Send Message (or carousel / AI).

Do not paste your URL in the public comment if you want them in DMs. Public links leak; DMs convert.

Lives are different

On Live Comments, Instagram only allows a private reply. There is no public live comment from the API. See Live comment automation.

Questions people ask

Can I rotate several public replies?

The trigger stores one Reply Message. Keep it generic. Variety belongs in the private DM, not in a list of spam-like public clones.
