Many agents, a single number
The regular WhatsApp Business app limits who can reply. With the API, your whole team serves the same number, with queues, departments and a shared history.

WhatsApp Business API integration for companies: infrastructure, team inbox and AI agents
I set up and maintain the official WhatsApp API (WhatsApp Business Platform) for your company: from the account and phone number to the infrastructure, a shared inbox for your team and AI agents that answer and qualify customers, connected to your systems.
- Free initial conversation
- Official Meta API, no hacks that get your number banned
- You talk directly to the person who sets it up and maintains it

When it makes sense
Signs your company's WhatsApp needs the API
The regular app only goes so far. The official API is what lets you grow without losing control.
Customers left waiting after hours
Messages sitting unanswered at night and on weekends. An AI agent replies right away, answers questions and hands over to a person only what needs one.
Notices and reminders sent by hand
Order confirmations, appointment reminders, payment notices: automatic messages using Meta-approved templates, tied to your system.
Conversations disconnected from your CRM and ERP
The customer talks on WhatsApp and the data gets lost. I connect the conversation to your CRM, ERP or internal system through APIs and webhooks.
Fear of the number being banned
Unofficial tools and careless bulk messaging put your number at risk. I use the official API and set up quality, opt-in and limits the right way.
An existing integration that keeps breaking
Unstable provider, a webhook that drops messages, support going down. I take it over, diagnose it and make it stable, with monitoring.
What I deliver
From the Meta account to support up and running
Every stage has a clear deliverable, so you can decide whether to continue.
Account and phone number setup
Meta business portfolio, business verification, phone number registration, business profile and approved message templates.
API infrastructure
Webhooks, queues, database, media storage and servers sized for your volume, with logs, backups and TLS.
Shared inbox for your team
A support platform with several people on the same number: queues, departments, conversation routing, transfers, labels and reports. I configure an existing one or build it custom.
AI agents handling conversations
LLM agents that answer using your company's data (RAG), look up orders and records, qualify the contact and hand over to a person when needed.
Integration with your systems
CRM, ERP, scheduling, payments, spreadsheets and automations (n8n, custom APIs): WhatsApp stops being an isolated channel.
Ongoing maintenance and monitoring
I keep the service running: failure alerts, number quality, Meta API updates, costs, and the evolution of flows and agents.

Agents integrated into operations
An authenticated MCP server on top of the product database, with safe tools scoped to each user, and agents that monitor quotas, send notices and run routines, with WhatsApp integration and n8n automations.

Platforms with asynchronous processing in production
Systems with background workers, queues, databases and AWS cloud carrying large data volumes, the same kind of foundation that WhatsApp support at scale requires.
Frequently asked questions
Before you start
What is the difference between the WhatsApp Business app and the WhatsApp Business API?
The app is built for one person or a very small team using a phone. The API (WhatsApp Business Platform) is Meta's official interface for companies: it allows several agents on the same number, integration with your systems, automated messages using approved templates and AI agents. It doesn't come with a ready-made support screen, which is why setting up the inbox is part of the project.
How much does the WhatsApp API cost?
There are two costs: Meta's, charged per message sent according to its category (marketing, utility, authentication or service) and the rules in force, and the cost of my consulting and of the infrastructure. Meta's pricing rules change over time, so I check the current table and estimate your monthly cost in the proposal, before any work starts.
Can I use the WhatsApp number my company already has?
In most cases yes, but it depends on how the number is used today. There are different paths depending on whether it is on the regular app, WhatsApp Business or another provider. I assess your case during the diagnosis and explain what happens to current conversations before any migration.
Do you use the official API or unofficial solutions?
I work with Meta's official API. Unofficial solutions, which connect WhatsApp Web through a QR code, violate the terms of service and can get the number banned, which is an unnecessary risk for a company.
How does the shared inbox work?
Your whole team answers through the same WhatsApp number on a web platform: conversations enter queues or departments, are distributed among agents, can be transferred and labelled, and keep a full history. Managers can follow reports, and the AI agent can handle conversations ahead of the team.
Does the AI agent answer on its own? Can it get things wrong?
It answers on its own within what you authorize: frequent questions, order lookups, qualification, scheduling. It uses your company's data and follows rules and limits we define together; when it doesn't know, or the topic is sensitive, it hands the conversation to a person. Conversations are logged for review and continuous tuning.
Do you maintain the service after it goes live?
Yes. I can keep the service running on an ongoing basis: monitoring, fixing failures, updates when Meta changes the API, tuning templates and agents, cost control and new integrations. The format is agreed in the proposal, as monthly hours or a fixed scope.
Is my data and my customers' data safe?
The infrastructure is designed with restricted access, encryption in transit, backups and control over who sees what. For privacy law compliance (LGPD in Brazil), I handle opt-in consent for outbound messages and how data is stored and sent to AI models, assessing case by case what can and cannot leave your environment.

Tell me in a few lines how your customer support works today. I answer personally and, if the official API isn't the best answer for your case, I'll say so.
