WHATSAPP BUSINESS API · AI CHAT
WhatsApp automation that turns messages into appointments
Your customers write on WhatsApp — usually in the evening, at the weekend, or while you're with a client. Brandmize answers every message instantly, clarifies the request and books the appointment straight into your calendar. 24/7, in more than 20 languages.
Why WhatsApp enquiries get lost
Messages arrive outside opening hours
Nobody on your team replies in the evening or at the weekend. By Monday the customer has asked someone else.
One number, several staff
Nobody knows who has already replied. Some messages get answered twice, others not at all.
Enquiries end up on a private phone
Without a shared inbox there is no overview, no follow-up and no handover when someone is ill or on holiday.
Whoever replies first wins the job
When a customer asks several providers, response time usually decides — not the better price.
How the automation works
We set up Meta's official WhatsApp Business API — not a workaround with a mirrored phone, but a verified business number.
- 1
Connecting your business number
A verified number via the official WhatsApp Business API. In most cases your existing number can be migrated.
- 2
The AI replies within seconds
It understands the request and answers recurring questions from your knowledge base — opening hours, services, directions, prices, whatever you provide.
- 3
Qualifying and booking
The AI recognises intent and urgency, checks your calendar in real time and books the right slot. Confirmation and reminder go out automatically.
- 4
Handover to your team
Anything the AI can't close lands in the shared inbox with the full conversation history. Your team picks up without asking twice.
- 5
Every conversation in the CRM
Each enquiry is captured as a contact — with source, intent and status. Nothing gets lost between chats and sticky notes.
Worth knowing
- Meta's official WhatsApp Business API — no grey area, no risk of being blocked through third-party tools.
- GDPR: data processing agreement, EU hosting of the platform, external data protection officer.
- Promotional messages require prior consent under German competition law (Section 7 UWG). We set the consent process up properly — replying to inbound enquiries is unaffected.
- Transparency under the EU AI Act: your contacts are told they are chatting with an AI system.
„Our internal processes were completely disorganised. Today everything is digitised — from patient communication to internal time tracking and holiday planning. It has noticeably taken the pressure off our team.“
Frequently asked questions about WhatsApp automation
What does WhatsApp automation cost?
It depends on scope: how many channels, what conversation volume, and which systems we connect. In the free strategy call we work through your specific case before you commit to anything.
Do I need the official WhatsApp Business API?
For automated replies with several staff, yes. The regular WhatsApp Business app is built for a single device and isn't designed for automation. We set up the official API and get your company verified with Meta.
Is WhatsApp automation GDPR compliant?
It can be — provided the basics are right: a data processing agreement, informing your contacts under Article 13 GDPR, a legal basis for the processing, and clean consent handling. That is exactly what we set up. WhatsApp belongs to Meta, so a transfer to the US is possible and is covered by EU standard contractual clauses.
May I send promotional messages on WhatsApp?
Only with explicit prior consent (Section 7 UWG), and you must be able to document that consent (Section 7a UWG). Replying to inbound customer enquiries is unproblematic. We build the consent process so it is verifiable.
How fast does the AI reply?
Within seconds — around the clock, including nights, weekends and public holidays.
Can the AI book appointments directly in my calendar?
Yes. We connect your calendar (Google Calendar, Microsoft Outlook, Cal.com among others). The AI checks availability in real time, books the slot and sends confirmation and reminder.
What happens when the AI doesn't know the answer?
It hands over to your team, with the full conversation history in the shared inbox. The customer never has to repeat themselves.
Which languages does it work in?
More than 20. The AI replies in whichever language your customer writes in.
