How to Move Instagram Comments to WhatsApp in India (2026)

You post a new drop. Within two hours there are a few hundred comments saying “price?”, “COD hai?” and “link pls”. You answer the first dozen. The rest wait overnight, and by morning most of them have scrolled on to another brand's reel.

Many Indian buyers would also rather finish the conversation on WhatsApp than in Instagram DMs. It is where they talk to their tailor, their kirana shop and their family, so it is where they feel comfortable asking about size, delivery and COD. Moving Instagram comments to WhatsApp is how a small brand meets them there without typing every reply by hand.

This guide explains the whole path from a comment to a DM to a WhatsApp chat, how to make your own wa.me link, the difference between the WhatsApp Business app and the WhatsApp Business API, and the opt-in rules that keep your number safe.

How do Instagram comments to WhatsApp chats work?

There is no direct pipe from an Instagram comment to a WhatsApp message. A comment is public, and WhatsApp only lets a business message someone who has agreed to hear from it. The clean way across is to let the buyer take the last step: the comment earns a private DM, and the DM hands them a link that opens WhatsApp.

1. A buyer comments your keyword on a post or reel, for example PRICE or WHATSAPP.
2. Instagram tells your tool through Meta's official API, in real time.
3. The tool sends a DM within seconds, with a short thank-you and a button.
4. The buyer taps the button and the next message brings your link. Here, that link is your wa.me link.
5. One tap opens WhatsApp with a chat to your business number, and the buyer sends the first message.

The last step matters. Because the buyer writes to you first on WhatsApp, the chat is one they started. That keeps you inside WhatsApp's rules, and it means your reply lands in a conversation they expect, not as a cold message from an unknown number.

How do you make a wa.me link?

A wa.me link is WhatsApp's own short address for “open a chat with this number”. It works on any phone with WhatsApp, and you do not need any tool to make one. Build it like this:

1. Start with wa.me/ and add your full number with the country code: wa.me/91XXXXXXXXXX. Leave out the plus sign, any leading zero, spaces and dashes.
2. Add a first message if you want one: put ?text= after the number, then the message. For example, wa.me/91XXXXXXXXXX?text=Hi%20I%20saw%20your%20reel.
3. Replace every space with %20. A link cannot have spaces in it, and the DM builder will not take one that does.
4. Test it on your own phone and on a friend's. The chat should open with your business name and the message typed in the box, ready to send.

Keep the typed message short and useful to you: “Hi, I want the price of the green kurta” tells you exactly which post the buyer came from. If you run several reels at once, give each one its own wa.me link with a different first message, so you know where each chat started.

How to send Instagram comments to WhatsApp with Inboxa in 4 steps

1. Use a business or creator account

Instagram's messaging API works only with professional accounts. In the Instagram app, open Settings, then Account type and tools, and switch to a business or creator account. It is free and takes a minute.

2. Connect with Instagram's own login

Inboxa runs on Meta's official Instagram API. You connect through Instagram's own login page and never type your password into Inboxa. Any tool that asks for your Instagram password is not using the official route.

3. Pick the post and the word

Choose one post or reel, several of them, or the whole account. Set a keyword such as PRICE or WHATSAPP, or answer every comment. End the caption with a clear ask: “Comment WHATSAPP and we will send you our number.”

4. Write the DM and paste your wa.me link

Write two or three lines in the language your buyers use, Hinglish included. Put the next step on the button, for example “Chat on WhatsApp”, and paste your wa.me link as the link. You can also add a short public reply under each comment, ask people to follow you first, or ask for their email before the link arrives.

For every automation, Inboxa shows DMs sent, replies, people engaged and link taps, and keeps a leads list of each commenter's @handle, the word they used and the steps they took, which you can download as a CSV. The Instagram DM automation page walks through every screen.

WhatsApp Business app or WhatsApp Business API: which do you need?

Both are free to download or sign up for, and both let buyers message your business. They differ in who replies and how many people can work from one number.

For the API, Meta charges per message in India: a marketing template costs approximately ₹0.86 and a utility template approximately ₹0.13, while your replies inside the 24-hour window after a buyer writes to you are free. Check Meta's current rate card before you budget. If a buyer opens the chat from your wa.me link and you answer within that window, your reply is a service reply.

If you are just starting, the free WhatsApp Business app is enough. Set a greeting message that lists your prices, sizes and COD terms, and add quick replies for the questions you type most. Move to the API when one phone can no longer keep up.

WhatsApp opt-in rules for Indian brands

WhatsApp is strict about who a business may message first. On the API, you need the person's opt-in before you send them a template message, and Meta watches how often people block or report a number. Too many blocks and your number's messaging limits drop, or it gets restricted.

• Let the buyer write first. A wa.me link does exactly this: the chat begins with their message, so there is nothing to prove later.
• Say what they will get. “Tap to chat with us on WhatsApp for prices and sizes” is clear consent to that chat. It is not consent to a daily sale broadcast.
• Ask before you add them to a list. If you want to send offers later, ask in the chat and keep a note of who said yes.
• Collect only what you need. Under India's DPDP Act 2023, keep a buyer's number for the reason they gave it to you, and remove it if they ask.
• Never scrape numbers from comments, bios or followers to message them. It breaks WhatsApp's rules and gets numbers banned.

Why Indian buyers prefer to finish on WhatsApp

Instagram is where Indian shoppers discover a product. WhatsApp is where many of them decide. They want to send a photo of their old kurta for size, ask whether you deliver to their pin code, check if COD is available, and sometimes forward the chat to a sister or a friend before paying. A WhatsApp chat makes all of that easy.

During Diwali and sale weeks this matters more. Comment volume spikes, and buyers ask the same five questions again and again. An automatic DM with your wa.me link answers the first question in seconds, and a well-written WhatsApp greeting answers the next four before you even pick up the phone.

Common mistakes to avoid

• A broken link. A space in the first message, a missing 91 or an extra zero, and the link opens nothing. Test it every time you change it.
• A personal number. Use a WhatsApp Business number, so your business name and catalogue show, and so your own chats stay separate.
• No greeting message. The buyer taps, writes “Hi” and hears nothing for hours. Set a greeting and an away message in the Business app.
• Messaging people who never wrote to you. Only answer the chats buyers start. Cold messages get blocked and reported.
• One link for every reel. Give each post its own first message, so you know which reel sells.
• Forgetting the public reply. A short reply under the comment shows other viewers that you answer.
