How to Auto-Reply to Instagram DMs (2026 Guide)
Set up automatic replies to Instagram DMs in minutes. A step-by-step guide to keyword auto-replies, Ice Breakers, and AI answers — using the official API.

If your DMs are full of the same questions — "how much?", "what's the link?", "is this available?" — you can answer them automatically. Here's how to set up auto-replies to Instagram DMs in a few minutes, so every message gets an instant answer even while you sleep.
What you'll need
- An Instagram Business or Creator account (a personal account can't use the API)
- A DM automation tool that connects through Instagram's official login — this guide uses Tendrify
- A few common questions you want answered automatically
Set up a keyword auto-reply
- 1Connect your Instagram account in Settings → Instagram.
- 2Create a new flow with a DM trigger.
- 3Add the keywords to watch for — for example: price, link, book.
- 4Choose the match mode: "exact" for the whole message, or "contains" to match the word anywhere.
- 5Write the reply — text, buttons, or a lead form — and turn the status on.
Turn on "any keyword" with a cooldown if you'd rather auto-reply to every DM without listing words. The cooldown stops the same person getting the same reply twice.
Add Ice Breakers for new conversations
Ice Breakers are tappable prompts — like "Pricing" or "Get the guide" — that people see when they open a chat with you. Tapping one starts the conversation and your automation answers instantly. Instagram doesn't allow messaging every new follower automatically, so this is the compliant way to greet new engagement.
Let AI handle the rest
Keyword replies handle the questions you can predict. For everything else, Conversational AI can answer in your voice using a knowledge base you provide — pricing, offers, FAQs — and hand off to you when a human is needed. Flows handle the known asks; AI handles the long tail.
Frequently asked questions
Can I auto-reply to Instagram DMs for free?
Yes. Tendrify's free plan lets you build DM keyword auto-replies and try them on your real account before upgrading.
Can I auto-reply to every DM, not just keywords?
Yes — enable "any keyword" so the flow replies to every message, and set a cooldown so nobody gets the same reply repeatedly.
Why does Instagram have a 24-hour window?
Meta's rules only let you message someone within 24 hours of their last interaction with you. It prevents spam — so send your reply promptly while the window is open.
