For agency owners who automate with AI
WhatsApp for agencies that build with AI: every client in one dashboard and an API your agent understands
You already build automations with Claude Code, Cursor or Codex and you need a WhatsApp base your AI can read and your client can use. Here every client's numbers sit in a single dashboard, each client's ad leads are recorded, the client follows everything in a portal on their phone, appointment messages are scheduled in the chat, and the API comes with OpenAPI, Postman, SDKs, an MCP server and llms.txt. GM Solutions Hub, the agency of ZapZap's founder, uses ZapZap with its own clients. R$15 per active number per month, no per-message fee. Create the account and connect your first client.

What holds you back today
Each client's WhatsApp lives on a different phone, and you only learn the number dropped when the client complains
The ad brings the lead, but you cannot see what happened in the conversation or how much became a sale
The non-technical client wants to see results on their phone, without learning another tool or creating an account
Commitments made in the chat ("I'll call you Tuesday") get lost, and the lead goes cold
You build with AI, but an API without a clear specification makes the agent invent endpoints
Per-message or tiered pricing breaks your margin exactly on the clients that grow the most
How it works with ZapZap
- 1
All client numbers in one dashboard
One number per client, each isolated, in the same account. You follow the status of all of them in one place and connect through a link, with the client scanning the QR code on their own phone.
- 2
Ad leads and sales per client
Tracking records the lead that came from an ad that points to WhatsApp, and the marked sale (in the dashboard, in the portal or by API) sends the conversion event back to Meta with the Pixel and token you configured.
- 3
Client portal and Performance tab
The client opens the portal on their phone and sees leads, sales and performance (response time, where the sale stalls, when people arrive and which conversations to recover). You choose the sections and the brand is theirs.
- 4
Schedule and automate with your AI
Schedule appointment messages in the chat or by API. And point your coding agent at the OpenAPI, llms.txt, SDKs and MCP server to build CRMs, reports and automations for your clients.
What to use
The features that matter here
The ZapZap modules that solve exactly the pain points of this scenario.
Tracking, Client Portal and Performance
From ad lead to sale, with the result visible to the client on their phone and the Performance tab showing where service loses the sale.
Message scheduling
In the chat, with date and time, and by API with scheduled_for. The commitment stops depending on someone's memory.
API for AI agents
OpenAPI and Postman in three languages, Node.js, Python and PHP SDKs, an open source MCP server and llms.txt, so your AI builds on real endpoints.
Ready-made messages to adapt
Examples to get started. Personalize them with the customer's name and your business details.
Hi! This is [Client Name]. I saw you came through our ad. Can I help you with price, delivery time or availability?
Agreed, [name]! I will get back to you tomorrow at 10am here. If you prefer another time, just tell me.
Prompt for your agent: "Use ZapZap's OpenAPI specification and write a script that lists the instances and produces a summary per client. Use only endpoints from the specification."
When operating clients' WhatsApp, the agency usually acts as a processor under LGPD: keep a data processing agreement, record contact consent and do not send real conversations to AI models without a legal basis. ZapZap is an unofficial solution: WhatsApp can limit or block numbers, and this must be agreed in writing with the client.
Frequently asked questions
Can I follow all my clients' WhatsApps in one place?
Yes. Each client is an instance in your account, and you see the status of all of them in one dashboard. Clients never mix with each other.
How do I follow the leads that came from each client's ads?
Tracking records the ad lead that points to WhatsApp and keeps the source on the lead card. Reach depends on the ad and Pixel setup, so validate with a small campaign before promising results.
Can the client see the metrics alone?
Yes, through the client portal, which opens by link or by number and password, on the phone, with no account. The Performance tab shows response time, where the sale stalls and which conversations to recover. You choose the sections.
Can I schedule messages so I do not forget commitments?
Yes. In the chat, with the Schedule action, and by API with scheduled_for on the simple send. Schedule what the contact already expected; scheduling does not replace consent.
What does the API offer to people who build with AI?
An OpenAPI specification and Postman collection in pt, en and es, official Node.js, Python and PHP SDKs, an open source MCP server and llms.txt. See the Build with AI guide on the blog.
Does GM Solutions Hub use ZapZap?
Yes. GM Solutions Hub, the agency of ZapZap's founder, uses ZapZap with its own clients. It is a first-party disclosure, with no result numbers.
