Instagram DM automation works by connecting a tool to the Instagram Messaging API through Meta's official OAuth flow. Once connected, the tool listens for trigger events — a keyword comment, a story reply, an inbound DM, a new follower — and sends a pre-written direct message to the person who triggered the event.
Liffio supports eight trigger types: comment-to-DM, story reply, live reply, DM keyword reply, follow gating, re-engagement, lead data collection, and welcome messages. Each automation runs independently on its own schedule. DMs are sent after a 10–60 second delay — configurable per automation — which distributes sends over time and avoids patterns associated with spam accounts. All sends go through Instagram's official API endpoints; no browser automation or password access is involved.
The tool operates 24/7 without requiring the account owner to be logged in. Automations can be paused, edited, or deleted at any time from the dashboard. Analytics track trigger count, DM delivered count, and link click-through per automation.
