2026 confirmed what was already coming: customers expect an instant reply on their favorite channel, and across much of Latin America and Spain that channel is WhatsApp. Answering by hand 24/7 doesn't scale; an AI agent does, as long as it's well built. A good WhatsApp agent isn't a decision-tree chatbot: it remembers the customer, answers with real data (it doesn't make things up), protects sensitive information and knows when to hand the conversation to a person. This guide shows how to build one with Floogos, step by step.
Define the agent's scope and tone
Before connecting anything, decide what job the agent does. A clear scope avoids generic answers and frustration:
- Which queries it resolves (order status, invoices, hours, FAQs...)
- What tone it uses: friendly, formal, with or without emojis, per your brand
- What it must NOT do and when to hand off to a human
- Which languages it serves
💡 Tip: start with a narrow scope and expand it. An agent that solves 5 cases well is worth more than one that answers 50 poorly.
Connect WhatsApp (Cloud API)
Floogos integrates with the WhatsApp Cloud API to send and receive messages on your business number:
- Register your number in WhatsApp Business / Cloud API
- Configure the token and inbound webhook in Floogos
- The agent starts receiving inbound messages and replying from the same number
- Enable the "typing…" indicator for a more human experience
💡 Tip: the same agent can also serve on Web, Telegram and Instagram without rebuilding anything; the channel is just the entry point.
Give it memory and context
The difference between a bot and a useful assistant is memory. In Floogos the agent remembers the conversation and the customer:
- Per-customer memory that persists across messages and visits
- Knowledge base (RAG) with your documents: policies, catalog, FAQ
- Conversation context so it doesn't re-ask what it already knows
- Cross-channel continuity: if it started on Web and continues on WhatsApp, it keeps the thread
💡 Tip: group several consecutive customer messages before replying. Avoid answering half-way when someone types in bursts, just like a human would.
Connect it to your real data
An agent that makes up data is a risk. In Floogos the agent queries your systems through workflows and answers with true information:
- Order and shipping status from your ERP, store or database
- Invoices and balances from your billing system
- Availability, pricing or appointments in real time
- Actions: open a ticket, book, register the customer as a lead in your CRM
💡 Tip: by connecting the agent to your CRM, every conversation can capture and qualify leads automatically, with no manual work.
Protect sensitive information
Before giving out private data (an invoice, an order with an address), verify who's on the other side:
- OTP identity verification before exposing sensitive data
- The agent only accesses the authenticated customer's data
- Clear rules on what information can be shared over chat
- Traceability: every query is logged
💡 Tip: OTP verification builds trust and protects you legally. It's a step customers appreciate, not an obstacle.
Hand off to a human when needed
The best agent knows its limits. With agent teams, the conversation moves to the right person without friction:
- Handoff to a specialist: Sales, Support or Admin
- The agent lets the customer know ("transferring you to support…") with a brief, natural delay
- The transcript and context travel with the conversation
- A human can step in at any time
💡 Tip: measure what gets handed off and why. Those cases are your best guide for gradually expanding what the agent solves on its own.

Frequently asked questions
Do I need the WhatsApp Business API?
Yes. For professional, automated service you use the WhatsApp Cloud API, which you connect to Floogos with your business number, token and webhook. From there the agent sends and receives messages.
Can the agent make up data?
It shouldn't, and that's the Floogos approach: the agent queries your real systems (ERP, billing, CRM) through workflows and answers with true information instead of improvising.
Can it hand the conversation to a person?
Yes. With agent teams, the conversation is handed to the right specialist (Sales, Support, Admin) carrying the transcript and context, and a human can step in whenever they want.
Does it work on channels other than WhatsApp?
Yes. The same agent serves on Web, Telegram and Instagram without rebuilding it, with continuous memory across channels. You change the entry point, not the agent.
A well-built AI agent on WhatsApp isn't a frustrating bot but another member of your team: available 24/7, with memory, with real data, secure, and with the judgment to hand off to a human when needed. With Floogos you build it once and deploy it across all your channels. The best time to start was yesterday; the second best is today.
