WhatsApp Business Auto Reply with AI: Keep Your App and Number

Quickchat added AI auto replies for WhatsApp Business that work with Coexistence, so an eligible number can stay in the WhatsApp Business app while Quickchat answers customers.

The walkthrough builds a fictional salon, Studio Alma. You write three short knowledge articles (hours and location, services and prices, changes and concerns) plus a Main Prompt, then connect WhatsApp. When a customer asks what a cut and blow-dry costs or whether the salon opens on Saturday, the Agent answers from those articles. The same chat also accepts voice notes and hairstyle photos. No code is involved, and the setup files are editable text you paste into the dashboard, not a one-click import.

A person can take over the same conversation from Quickchat's Inbox, and replies sent from the Business app are recorded there too. To hand a chat back after an Inbox takeover, you choose AI Agent. After a Business app reply, the next customer message can return the chat to the AI once four hours have passed without messages. The example collects appointment preferences, and a stylist confirms availability because no booking calendar is connected.

Coexistence changes a few things in the app. You need WhatsApp Business 2.24.17 or newer. Group chats stay outside the integration, broadcast lists become read-only, and linked devices disconnect during onboarding. Windows and WearOS aren't supported in this mode. Disappearing messages, view-once messages, and live location are turned off for individual chats. The number can disconnect after about 14 days without the primary phone being used. Quickchat doesn't import old chats or your address book, and Meta decides whether a number is eligible during signup.
