How to Auto-Reply to Instagram DMs and Comments (Step-by-Step)

Answering every comment and DM by hand does not scale — and the replies people get hours later rarely convert. The fix is to set up automatic replies on Instagram so that comments, DMs, and story interactions get an instant response, 24/7. This guide shows you exactly how to do it, step by step, with no code and without risking your account.

Before you start: do it the safe way

There are two ways to automate Instagram replies. One uses the official Instagram API from Meta — this is safe and allowed. The other uses unofficial bots or browser extensions that mimic a human — this violates Instagram's terms and can get your account restricted. This tutorial uses the official, safe method via Send DM, an official Meta Business Partner.

How to send an automatic DM from a comment (comment-to-DM)

This is the highest-impact automation: when someone comments a keyword on your post or reel, they instantly get a DM. Here is how to set it up:

1. Connect your Instagram account. Sign up free and connect via the one-tap official Meta login.
2. Pick the post or reel you want to automate.
3. Choose a trigger keyword — something you will tell your audience to comment, like "LINK" or "GUIDE".
4. Write the DM that should be sent, including your link or offer. You can personalize it with the commenter's name.
5. Go live. From now on, anyone who comments that keyword automatically receives your DM in seconds.

Then add a clear call to action to your caption — for example, "Comment LINK and I'll DM you the guide." That single line can dramatically increase comments and DMs. For more on this, see our Instagram DM bot guide.

How to auto-reply to incoming DMs

1. Open your DM automation settings.
2. Create a keyword trigger — for example, "PRICE" or "BOOK".
3. Write the reply, or build a multi-step flow that asks a question and routes the conversation.
4. Add a fallback message for DMs that do not match any keyword.
5. Activate it. Incoming DMs now get instant, around-the-clock responses.

How to auto-reply to story mentions and replies

Story interactions are pure intent — someone cared enough to react. To automate them:

1. Enable story automation.
2. Choose what to respond to: mentions, reactions, or replies.
3. Write the DM to send when it happens.
4. Save. Now every story interaction gets an instant reply while interest is at its peak.

Tips for auto-replies that actually convert

• Sound human. Write the way you talk. Add an emoji and the person's name.
• One clear next step. Every auto-reply should point to a single action — a link, a reply, or a question.
• Capture the lead. Ask for an email or phone number inside the flow so you can follow up later. See Instagram lead generation.
• Test your keywords. Make them short, memorable, and unlikely to be typed by accident.

How long does this take to set up?

Your first comment-to-DM automation takes about five minutes. Once you see it working, layer in DM auto-replies, story automation, and a welcome message for new followers.

The bottom line

Setting up automatic replies on Instagram is simple, safe, and fast when you use the official API: connect your account, pick a keyword, write the message, and go live. Start free and set up your first auto-reply today — no credit card, no code.
