Auto-send a DM when someone comments a keyword on your Instagram post or reel, with an optional public reply. Set it up in your browser, no code.
Sign in and connect your Instagram Business or Creator account through PostPeer’s managed OAuth. No developer app or App Review.
Choose a specific post or reel (or every post), then set the trigger words that should start a DM.
Add your DM and an optional public reply. PostPeer watches for matching comments and sends the DM automatically.
Set words like “link” or “guide”. A matching comment triggers your DM in real time. Leave keywords empty to reply to every new comment.
Drop a public reply under the comment too, like “Sent you a DM!”. Add a few alternatives and PostPeer rotates them so it reads naturally.
Run an automation on one post or reel, or across every post on the account. Pause, edit, or delete it anytime.
PostPeer subscribes the account to Instagram webhooks and handles delivery with retries. No webhook server, no App Review on your side.
This tool runs on the PostPeer Instagram Comment to DM API. Create keyword-triggered DM automations programmatically, with unlimited connected accounts.
