Instagram comment-to-DM automation: build it on the API, or ship it today for free

Description and use

A compliant workflow that automatically sends DMs to Instagram commenters who use a specific keyword, built on Meta’s official API and respecting platform limits.

Problem

Clients, marketing teams, or creators want to automatically send a link to users who comment a specific keyword (e.g., "GUIDE") on Instagram posts, stories, or DMs.

Outcome

Automated, compliant comment‑to‑DM flows that deliver links instantly to commenters, increasing engagement and conversion while adhering to Meta’s platform rules.

Workflow

• 1. Connect the creator’s Instagram professional account via Meta login to obtain an access token.
• 2. Set up a webhook to receive comment, story reply, or DM events from Meta.
• 3. On each event, check the comment text against configured keywords (case‑insensitive, whole‑word, emoji‑aware).
• 4. If a match is found, send a private reply DM using the /messages endpoint, referencing the comment ID.
• 5. Ensure the DM is sent within 7 days of the comment and within the 24‑hour messaging window for follow‑ups.
• 6. Optionally add public replies, message variations, or follow‑gate logic for enhanced engagement.

Evidence

Four pieces of Meta's official API, no scraping: 1. Login and token. 2. Webhook. 3. Keyword match. 4. Private reply.

Source

One private reply per comment, within 7 days, so the link belongs in that first DM
