How to get WhatsApp and Instagram messages in one inbox

The short answer

To see WhatsApp and Instagram messages in one place, connect both accounts to a single inbox tool: Meta's own business inbox, a shared customer-messaging tool or a business platform that includes an inbox. Before you can connect them, Instagram needs to be a professional account and WhatsApp needs a number on Meta's business platform rather than only the free app.

Connecting the channels is the easy part. The parts that stop messages slipping through are a rule for who answers, the same saved answers on both channels, and a customer record that shows what was said wherever it was said. The rest of this post covers each one.

Why two separate apps cause missed messages

Most small businesses start by answering WhatsApp in the WhatsApp app and Instagram in the Instagram app, often on the owner's phone. That works until it doesn't:

• A customer asks a question on Instagram, then follows up on WhatsApp, and you answer them twice or contradict yourself.
• Instagram messages from people who don't follow you land in a separate requests folder and sit there for days.
• Only the person holding the phone can see the conversation, so nothing gets answered when they're busy or off.
• A booking or order agreed in a chat never makes it into the calendar or the order list.
• Nobody can see a customer's history without scrolling through two apps.

One inbox doesn't fix all of these on its own, but it removes the main cause: having to remember to check two places.

What you need before you connect anything

1. 1

   An Instagram professional account

   Switch your Instagram account to a business or creator account in the app settings. Business tools can only read and reply to messages on professional accounts. Some tools also ask you to link a Facebook Page, so check what your chosen inbox needs.

2. 2

   A WhatsApp number on Meta's business platform

   The free WhatsApp Business app is designed to be used on a phone. To connect WhatsApp to an inbox tool, the number needs to be registered on the WhatsApp Business Platform, usually through a guided sign-up inside the tool. Whether a number can keep working in the phone app at the same time depends on your provider and country, so check before you move your main number.

3. 3

   A Meta business account

   Both connections go through a Meta business account (sometimes called a business portfolio). Have admin access ready, and expect Meta to ask you to confirm the business and the phone number.

4. 4

   Someone who owns the inbox

   Decide who answers by default and who covers when they're away. An inbox nobody owns is just a tidier place to miss messages.

Meta changes its account steps, names and requirements fairly often. Follow Meta's current help pages for WhatsApp Business and Instagram messaging, and the instructions from whichever inbox tool you choose, rather than a guide that may be out of date.

The 24-hour reply window, explained

This is the rule that catches most businesses out when they move from the phone apps to an inbox tool. When a customer messages you, you can reply freely for 24 hours from their last message. That window resets every time they write again.

• WhatsApp: outside the 24-hour window you can only start a conversation with a message template that Meta has approved. Meta may charge per template message, depending on the type of message and the customer's country.
• Instagram: messages sent through business tools follow a similar 24-hour window, with limited exceptions. You can't message people who have never contacted you.
• In both cases, the customer must be someone you're allowed to contact. Opt-in rules and message categories are set by Meta and can change.

In practice, reply to buying questions inside the window, and don't leave a promised follow-up until the next day without checking whether you'll still be able to send it. Check Meta's current WhatsApp pricing and messaging policies before you plan any messages you'll send first, such as reminders or offers.

Your options for one inbox

The right choice depends on what happens after the message. If a chat usually ends with a quick answer, a messaging tool is enough. If it usually ends with a booking, a sale or a follow-up campaign, it helps when the inbox sits next to the calendar, the store and the customer record.

How to set up one inbox that actually works

1. 1

   Connect both channels and send a test message

   Message your business from a personal WhatsApp and a personal Instagram account. Check that both arrive, that replies reach the customer and that the requests folder isn't hiding anything.

2. 2

   Use the same saved answers on both

   Prices, hours, location, how to book and how to order should read the same whichever channel the customer used. Update them in one place when something changes.

3. 3

   Send one booking link and one shop link

   Use the same links in your WhatsApp profile, Instagram bio and saved replies, so bookings and orders land in the system built for them instead of in a chat thread.

4. 4

   Write down the hand-over rules

   Decide which conversations always go to a person: complaints, refunds, custom quotes and anything sensitive. If an AI replies first, these are the moments it should step back.

5. 5

   Link conversations to the customer

   When a chat becomes a booking or an order, it should appear on the same customer record, so the next person to reply can see what was agreed.

6. 6

   Set checking times

   Even with one inbox, answering every message the moment it arrives wrecks your day. Pick set times, answer buying questions first, and tell customers when to expect a reply.

How this works on Darvix AI

On Darvix AI, WhatsApp, Instagram DMs and website chat arrive in one unified inbox, each conversation linked to the customer's record in the CRM. You connect WhatsApp and Instagram from the dashboard through Meta's own sign-up, without needing a separate messaging provider.

Jenny, the customer support AI employee, can answer routine questions on both channels using what you've taught her about the business, and book, reschedule or cancel appointments inside the chat so the booking lands in the calendar. When a conversation needs a person, she hands it over. Keyword replies, welcome messages and follow-ups can run on their own with WhatsApp automation and Instagram automation. You can also send WhatsApp and email campaigns to customers who have agreed to hear from you.

Meta's own WhatsApp message fees still apply on top of your Darvix plan. Paid plans start at $22 a month; see pricing for the current limits.

The bottom line

One inbox for WhatsApp and Instagram is mostly a setup job: a professional Instagram account, a WhatsApp number on Meta's business platform, and a tool that shows both. What makes it work day to day is everything around it: one owner, the same saved answers, one booking link, clear hand-over rules and a customer record that remembers.
