How to Set Up Instagram Auto Reply (Comments, DMs, and Stories)

To set up Instagram auto reply: switch to a professional account, connect it to an official-API tool through Meta’s authorization screen, pick a trigger (a comment, a DM, or a Story reply), add the keyword and the reply, then test the whole path from a second account. The first workflow takes about five minutes.

Open the comment-to-DM template in SocialGrow to follow along. There’s a 7-day free trial, no card needed.

Which auto reply do you need?

You want to…	Trigger to use	Typical reply
Send a link to everyone who comments a keyword	Comments on a Post/Reel	The guide, product, or booking link the post promised
Answer the same DM question automatically	Sends a DM	Prices, hours, a FAQ answer, or a handoff to your team
Follow up when someone replies to your Story	Replies to a Story	The resource the Story offered
Reply when someone DMs you one of your posts	DMs a Post/Reel	Details or the link for that exact post

All four reply only to someone who interacted with you first, which is the supported way to message people under Meta’s rules. Nothing on the official API can DM someone just because they followed you.

Before you start

1. Use a professional account. Business and Creator accounts work; personal accounts can’t use Meta’s messaging API. Switching is free in Instagram settings.
2. Turn on message access for connected tools. In Instagram, go to Settings → Messages and story replies → Message controls and make sure connected tools can access messages.
3. Have one clear offer ready, such as a link, guide, price list, or booking page that you can deliver in one message.

Set up a comment-to-DM auto reply in SocialGrow

1. Connect Instagram. Sign in, then connect your account through Meta’s authorization screen. SocialGrow never asks for your Instagram password.
2. Create an AutoDM. Open AutoDM and start from the comment-to-DM template, or create a new automation and choose the trigger Comments on a Post/Reel.
3. Pick the post and keyword. Choose the post or Reel and the word people should comment, such as GUIDE or PRICE. Use a word that won’t show up in ordinary comments.
4. Write the DM. Deliver what the post promised first. Add up to three buttons (for example “Get the guide” and “Book a call”) and each one counts its own clicks.
5. Add public replies (optional). A short “Sent, check your DMs” tells other viewers the keyword works and encourages more comments. Add 3 to 10 variations. SocialGrow picks one at random for each comment and @mentions the commenter, so your replies don’t all look identical.
6. Decide on extras. Optionally ask for an email or phone number to capture the lead, or require a follow before the link is sent.
7. Test from a second account. Comment the keyword and confirm the public reply, the DM, the link, and the lead record all work.
8. Turn it on and watch the first day. Check delivered messages, button clicks, and any failures in the automation’s activity log.

Keep the caption call-to-action specific: “Comment GUIDE and I’ll DM you the checklist” beats “Comment below for more info.”

Set up a DM keyword auto reply

Look through recent DMs for the question you answer most often. Create an automation with the trigger Sends a DM, set the keyword (for example price), and write an answer your team is comfortable sending without extra context.

Test the spellings people actually use. Route anything sensitive or unclear (complaints, payments, custom quotes) to a person instead of trying to automate it. Those conversations stay in SocialGrow’s DM inbox, where you can answer them yourself.

Set up a Story reply auto reply

Create an automation with the trigger Replies to a Story and write a message that refers to the Story (“Here’s the template from today’s Story”). Put a clear prompt on the Story itself, such as “Reply TEMPLATE and I’ll send it”, so people know what to do. For ideas that get more people replying in the first place, see how to get more Instagram Story replies.

What about Instagram’s built-in AI and saved replies?

Instagram has several native tools that people search for as “auto reply” or “generate a reply”, but they solve a different problem:

• Saved replies let a professional account type a shortcut (for example /hours) to fill in a pre-written message. You still send each one by hand.
• Write with Meta AI helps you write or rephrase a message in a chat on the mobile app. It drafts; you send.
• AI auto replies for creators let a creator AI built in Meta AI Studio answer messages from an audience you choose. Meta is rolling it out gradually, it is mobile-only, and replies are labelled as AI.

None of these lets you send a specific link to everyone who comments a keyword, or record leads from those conversations. For that you need a keyword automation on the messaging API. Our guide to Instagram’s “Generate a reply” and AI reply tools compares them in detail.

Handle the comments automation shouldn’t answer

Keyword automations deal with the predictable comments. For everything else, SocialGrow’s Comments inbox uses AI to sort comments into questions, feedback, praise, automation keywords, and noise, and it puts the ones that need a human answer in a To reply list. You answer real questions without scrolling past hundreds of keyword comments. The AI only sorts; every reply is still written and sent by you.

Common setup problems

The trigger did not fire

Check that the automation is on, the right post is selected, and the keyword matches what was commented. Test from a separate account, because comments from the connected account itself don’t trigger it.

The DM did not arrive

Open the automation’s activity log. If it shows a delivery error, check that message access for connected tools is turned on in Instagram settings and that the account is still connected.

Replies go to the wrong workflow

The keyword is probably too broad. Pick a more distinctive word and test it against ordinary comments.

A follow-up keeps sending after the person responds

Check the stop condition and test it end to end. Don’t tell people to reply STOP unless the workflow actually stops on that reply.

Measure what happened

Messages sent is not the same as leads or customers. Track, for each campaign:

• Matching comments or DMs
• Delivered replies and failures
• Button clicks
• Leads who shared contact details
• Bookings or purchases you can attribute to the workflow

Is auto reply safe for your account?

Auto replies that run on Meta’s official API and only answer people who interacted with you first are the supported way to automate Instagram messages. Read the Instagram automation safety checklist for what to check before you go live.
