WhatsApp CRM: customer records from your chats.

What a WhatsApp CRM actually is

A CRM is the list of your customers and everything you know about them. A WhatsApp CRM is the same list, filled from WhatsApp conversations: a new chat becomes a contact, a question becomes a lead or a ticket, and the next step — a quote, a reminder, a follow-up — is attached to the person, not lost in a phone.

There are two ways to get there. You can organise customers inside the WhatsApp Business app itself, with no other software. Or you connect your number to the WhatsApp Business Platform, where Meta's Cloud API delivers every incoming message to your own server as a webhook, and your CRM stores it. The second is what lets a team, a dashboard or an AI agent work on the same conversations.

Keeping the app while adding a CRM

Since Meta opened onboarding for WhatsApp Business app users — called “coexistence” in its support channels — a business can connect its existing app number to the Cloud API through a provider's Embedded Signup flow. It keeps answering one-to-one from the app, while software sends at volume, and WhatsApp keeps the history of both in sync.

Meta lists precisely what moves across. Individual chats and contacts are supported on the API side; the most recent 6 months of chat messages can be synchronised. The app's own tools — labels, quick replies, greeting and away messages, catalog, business profile — keep working in the app but are not exposed through the Cloud API. So labels you set on the phone will not appear in your CRM: the CRM needs its own fields.

What the 24-hour window means for a CRM

When a customer messages or calls you, a 24-hour customer service window opens, and resets each time they write again. While it is open, your CRM can send any free-form message. Once it closes, only pre-approved message templates can go out. Messages sent from the WhatsApp Business app are not bound by that window and do not open or extend it on the API side.

On cost, Meta does not charge for messages customers send you, and each business phone number gets its first 1,000 service messages a month free; templates are charged per message by category. The rates and the October 2026 changes are in our article on WhatsApp Business API pricing.

Pitfalls to check before you connect

• The history sync has a deadline. After onboarding an app number, the provider has 24 hours to synchronise contacts and history; otherwise the business must be offboarded and go through the flow again. Keep the app open on the phone while it runs.
• Broadcast lists stop. Existing lists become read-only and new ones cannot be created; campaigns move to templates sent from the CRM.
• Linked devices are unlinked. All companion devices are disconnected at onboarding and must be re-linked; WhatsApp for Windows and Wear OS are not supported as companions, and a customer writing from one of them triggers no webhook, so the message never reaches your CRM.
• Throughput is capped. A number used in both the app and the Cloud API has a fixed throughput of 20 messages per second.
• Group chats stay out. Only one-to-one chats are synchronised; customer groups remain in the app.

When a connected CRM is worth it

If one person answers a few customers a day, the WhatsApp Business app with labels is often enough. A connected CRM pays off when several people answer, when follow-ups slip, when you need to know which enquiry became a sale, or when an AI agent should answer, book or qualify before a person steps in. That is the layer we build in our WhatsApp AI agents — for example the guest CRM and WhatsApp booking assistant of a restaurant group's booking platform, or BrokerPilot for insurance brokers.
