WhatsApp automation on the official Business API

Quotes, bookings, complaints and photos of broken parts all arrive on the same number. Someone answers between meetings. At nine in the evening the messages keep coming and nobody sees them until morning.

None of it reaches the CRM. When that person is on holiday, the company is quietly closed on its busiest channel.

The common fix is a second phone, which doubles the problem instead of solving it.

The number moves to the WhatsApp Business API, so the conversation stops living in one handset. From there n8n routes every message and an AI model reads what it is about.

• Instant first reply. Common questions on price, opening hours or order status get answered from your own documents, in your own wording.
• Real availability, not a promise. Booking requests check Cal.com or your calendar, then confirm the slot and set the reminders.
• Handover to a person. Anything sensitive goes to a shared inbox with the whole thread attached, so nobody asks the customer to repeat themselves.
• Every thread in the CRM. Contact, deal and history updated automatically, which is what makes the channel survive a resignation.

Outbound messages use approved templates and respect the opt-in rules, because Meta suspends numbers that do not.

Complaints, medical questions, anything about money beyond a standard price: all of it goes to a person immediately, with a line saying why it was escalated.

The assistant says it is an assistant when asked. Pretending otherwise breaks trust the first time a customer notices, and customers always notice.

A clinic running its messaging this way is described in the Lucas Miranda case.

Two to four weeks is the usual range, and the calendar depends partly on Meta. Verifying the business and approving the first templates can take several days that nobody controls.

We run the assistant against real past conversations in a sandbox before a customer ever writes to it. That habit, and the rest of how we work, is in the process section.

Book the AI and operations audit and we map what actually arrives on that number. You get a ranked plan in two working days, with its fee credited against the first project.

Have your company verification details ready along with a month of exported chats. Those chats are the training material, and nothing else describes your business as accurately.

Most of these builds run on n8n, explained in the n8n page. The service that covers the whole thing is automation and AI systems.
