How to Set Up Instagram Auto Reply: Keywords, Comments, Stories
To set up Instagram auto reply, use a business or creator account, connect it to a tool that can answer direct messages, then write a rule: a trigger (a new message, a keyword, a comment or a story reply), the reply text and a safety condition. In Infinall AI you do this in Distribution, Account, Automations: choose New rule, fill in When and Then, choose Create rule, then Turn on.

An Instagram auto reply is a message that goes out by itself when someone does something you named: sends a first message, types a keyword, comments on a post or replies to a story. Setting one up takes the same steps in any tool. You need a professional account, a place where the rules run, a short reply that answers the question, and a check that keeps the rule away from complaints. This guide walks through those steps in a tool-neutral way, then shows each one in the Infinall AI Automations tab, where rules are written as a plain sentence and running them uses no credits.
| Trigger (When...) | Fires when | Good first use |
|---|---|---|
| a message arrives | Any direct message comes in | A short note saying when a person will reply |
| a message mentions a word | A message contains one of your words | Send the price list when someone types PRICE |
| someone writes for the first time | A person messages you for the first time | A welcome and the three things people usually ask |
| someone replies to a story | Someone answers one of your stories | Thank them and tag them as a lead |
| someone comments | Someone comments, optionally with trigger words | Send the product link to people who comment LINK |
| someone reacts to a post or message | Someone reacts with any emoji | A light thank you, used sparingly |
How to Set Up Instagram Auto Reply: Keywords, Comments, Stories
Use a business or creator account
Most auto reply tools need an Instagram business or creator account connected to them, not a personal one. Switching is done in the Instagram app settings. Check the help page of the tool you choose for the exact account type it needs, since menu names change between app versions.
Choose where the rules will run
Auto replies run in a tool that connects to your Instagram account through the platform's official messaging access, so it can only do what Instagram allows. Pick one place for your rules, so two systems do not answer the same person twice. Make sure the tool can also hand a chat back to you, because some questions need a person.
Pick one trigger to start with
List the questions you answer the same way every day, such as price, delivery areas, sizes or a link. Pick the most common one and decide what starts the rule: any new message, a first message, a message with a keyword, a comment on a post or a reply to a story. A narrow trigger, like the word PRICE, is safer than replying to every message.
Write a short reply that sounds like you
Answer the question in the first line, then say what happens next, for example that a person will follow up. Keep it short and avoid anything that reads like a bot pretending to be human. If the answer is a price list or menu, send it as a picture or PDF instead of a long block of text.
Add a safety condition and a handover
A rule should never send a cheerful automatic reply to an angry customer. Add a condition that skips messages with words like refund, scam or broken, and hand those chats to a person. Also set a cooldown, so the same person is not answered again and again.
Test it, turn it on, then read the results
Ask a friend to send the trigger word from another account and check what arrives. Turn the rule on only when the wording is right. In the first week, read the runs of each rule and fix any reply that confuses people.
How to set up Instagram auto reply in Infinall AI
First connect your Instagram account in Distribution, then Account, then the Accounts tab. Then:
- Pick the brand in the brand switcher at the top of the left menu. Rules belong to one brand.
- Open the Automations tab and choose New rule. The button is switched off until a messaging account is connected.
- Under When..., pick the trigger. For a keyword or comment trigger, type the words in Trigger words, separated by commas: up to 20 words, each up to 60 characters.
- Optional: choose + Add condition, for example the message does not say, or they follow you.
- Under Then..., pick Reply with and write the text, up to 1000 characters. Choose Add a step for Send media, Tag them, Wait minutes or Hand to a human.
- Set Same person can re-fire after if you want something other than the default of 24 hours.
- Choose Create rule. The rule is saved as Not on yet and messages nobody until you choose Turn on.
In a hurry, start from a template under Start from a template (optional): Answer price questions instantly, Welcome first-time messagers, Never auto-reply to angry mail, Turn story replies into leads or Thank commenters automatically. Read what it filled in and change the wording before you turn it on.
Common mistakes and how to avoid them
- Replying to everything. A rule on a message arrives answers every chat, including complaints. Use a keyword trigger, or add the condition the message does not say with words like refund or scam.
- Expecting an office hours rule. Infinall AI has no time of day trigger, so the After-hours acknowledgement template answers every incoming message once per cooldown, not only at night.
- Forgetting the cooldown. Without one, two automatic systems can talk to each other. The default is 24 hours, and you can set it up to 720 hours.
- A media step with no file. A Send media step needs a JPEG, PNG, GIF, MP4, AAC, WAV or PDF file of up to 25 MB, or the rule will not save.
- Leaving handed over chats unread. Hand to a human stops the rule and flags the chat. Answer it in Engage, then Messages, where an AI reply suggestion is available if you want a draft.
Free vs Pro, and when another tool fits better
Creating, turning on, pausing and deleting rules uses no credits, and Free and Pro accounts both see the Automations tab. A rule needs a connected messaging account, and connecting a new account is a Pro feature, so in practice you need Pro to start. Pro includes 2 free connections shared by social and ad accounts; after that each account uses 300 credits a month, with the price shown before you confirm.
Free gives 1,000 credits every month with no card. Pro is $10 for the first month, then $30 a month or $299 a year (India: Rs 999 first month, then Rs 2,899 a month or Rs 33,999 a year), with 3,000 credits a month.
Be honest about fit. If you only get a few messages a day, typing the answers yourself costs nothing and needs no other account. If you want a full chatbot with a visual flow builder and many branches, a dedicated chatbot tool fits better: Infinall AI has no canvas or node editor, and the rule window allows up to 6 steps and 6 conditions. Infinall suits you when you also want to make the posts, plan them in the calendar and answer comments and messages in one place.
