How Do I Get One Inbox for WhatsApp, Instagram and Messenger?

By Alva Chew 4 min read Updated November 11, 2026

Connect all three to AeroChat and work them from one inbox. WhatsApp, Instagram and Messenger conversations land in the same AeroChat inbox, with assignment, tags, notes and search. AeroChat also does the routine jobs on all three: it answers product questions, checks orders in your store, sends payment links and opens return requests. Your team sees everything and steps in only where needed.

Why three apps are hard to run

All three belong to Meta, but on a phone they are still three apps, plus the Meta Business Suite inbox. Sellers describe answering WhatsApp on one phone, Instagram on another, and finding an unread Messenger chat days later. When two people share the work, nobody is sure who replied to whom.

The usual fixes and their limits

  • Meta’s own inbox. Meta Business Suite brings some of these messages together. Check Meta’s help pages for which WhatsApp setups it supports. It doesn’t check orders in your store or take payment.
  • A shared inbox tool. It collects the chats and lets a team split them. Every reply is still typed by a person.
  • Separate auto-replies on each app. Greetings and away messages, set up three times.

How to handle it with AeroChat

Connect WhatsApp with embedded signup, then Instagram and your Facebook Page. Write your workflows once and they run on all three. On Instagram, AeroChat also replies to comments automatically and moves the conversation to the DM. On WhatsApp, it uses approved message templates when you need to message a customer outside the 24-hour window. See WhatsApp message templates.

Customer (Messenger): Do you have this lamp in white? How much with delivery to Quezon City? (example)

AeroChat: Yes, the Arc lamp comes in white. It’s US$39, and delivery to Quezon City is US$4 (example), so US$43 in total. Would you like to order it?

Customer: Yes

AeroChat: Here’s your payment link for 1 x Arc lamp, white, US$43. I’ll confirm your order here once it’s paid.

Behind the reply: stock and the shipping rate came from the store. Payment is detected automatically and the order is created.

Copy this into AeroChat

On WhatsApp, Instagram and Messenger, answer from our product details and store.

  1. Product and stock: check the variant is in stock before you say it is available.
  2. Price with delivery: give the product price plus our shipping rate for the customer’s area.
  3. Buying: confirm the item, variant and total, send a payment link and confirm the order when the payment is detected.
  4. Order status: verify the order number and email or phone, then give the status and tracking link.

Instagram comments asking for a price: reply that we’ve sent the details by DM, then answer in the DM. Hand complaints to our team with a summary.
