WhatsApp API for Lawyers and Law Firms
A client messages after hours, asks about the status of their case and disappears if nobody answers quickly. Every case that slips away because of a slow reply is a fee that walks out the door.

What holds you back today
A lead arrives from Google or Instagram and the firm takes hours to reply. By the time the lawyer opens WhatsApp, the client has already signed with someone else.
Lawyers and interns lose the day answering the same question: what is going on with my case, counselor?
A personal number mixed with the professional one, with no separation of contacts by client and no control over who has access to the conversations.
Manual screening of cases that are not even in the firm's practice area, hours spent on people who were never going to become clients.
A client asks for a case update on Saturday night and nobody at the firm is online to reply.
A first contact with no standard: each team member collects the case details differently, information gets lost and the lawyer starts from scratch.
How it works with ZapZap
- 1
Lead arrives on WhatsApp
The contact comes from the website, Google or an ad straight to the firm's number. The AI replies instantly, even at night or on weekends, and greets with the firm's name.
- 2
Screening and case intake
The AI or the Flow Builder asks for the area (labor, civil, family), a case summary and the urgency. It filters out anyone who does not fit the firm's profile before taking up the lawyer's calendar.
- 3
Handed to the lawyer with context ready
A qualified case arrives with the details already organized. The lawyer takes over the conversation and books the first consultation without repeating questions the client has already answered.
- 4
Updates and follow-up
Notices of case movements, hearings and deadlines go out scheduled through the Marketer, with humanized sending that lowers the risk of the number being blocked.
What to use
The features that matter here
The ZapZap modules that solve exactly the pain points of this scenario.
Flow Builder
Builds the script for the first contact with no code: collects name, area, case summary and documents, always in the same pattern, so no information gets lost.
Anti-block
A number that sends case updates to many clients draws WhatsApp's attention. Automatic typing indicator, delays and non-standard sending lower the risk of blocking.
Marketer
Sends scheduled notices about hearings, deadlines and case movements to the right list of clients, without anyone at the firm having to message them one by one.

Hello, this is Damazio Advogados. We received your inquiry about the labor issue. To understand your case, tell me: are you still with the company or have you already been let go?
Dear client, your case no. 0001234-56.2025 had a movement: the opposing party's answer was filed. Our team is already reviewing it and will get back to you with the next steps by Friday.
We received your documents and your case is with the responsible attorney. What is the best time for a 15-minute initial conversation: Tuesday at 2 PM or Thursday at 10 AM?
Mind professional confidentiality (the OAB Code of Ethics, the Brazilian Bar Association) and LGPD (Brazil's data protection law): record the client's awareness of service over WhatsApp, restrict access to conversations to authorized staff and configure the AI only for screening and data collection, never for legal advice. Unofficial number (managed instance), subject to WhatsApp's terms of use.
Frequently asked questions
Does using WhatsApp this way breach professional confidentiality?
Conversations stay on your own instance, on your number, and you control who at the firm has access. The AI does not share data between clients. We recommend recording the client's awareness that they are being served over WhatsApp, as you would already do with email or phone.
Is it Meta's official WhatsApp?
No. ZapZap API uses managed instances of regular (unofficial) WhatsApp. The advantage for the firm is not depending on template approval for every notice and having a fixed cost per number, with no per-message charge.
Could the AI end up giving wrong legal advice?
You configure the AI only for screening, data collection and scheduling. It is not built to issue opinions or answer the merits of a case. As soon as it identifies a real case, it hands it over for the lawyer to take.
Can I separate by practice area or by lawyer?
Yes. Each instance is an independent number. You can have one number for labor, another for civil or family law, each with its own AI, its own service flow and its own team.
How much does it cost and how does billing work?
R$15 per active number per month, prepaid, with no charge per message sent. You get a welcome credit when you create the account, subject to the current campaign. Test the service and the screening before putting it into production at the firm.
