VantegrateNative API integrationIntegrate Brevo with AI agentsthat answer every lead on WhatsApp
Vantegrate's AI agents connect to your account through the official Brevo API: they read and write your contacts, lists and deals, answer and qualify leads on WhatsApp, and log every conversation where it belongs. Your data keeps living in your Brevo account.
How the data flows
What does it mean to integrate Brevo with Vantegrate's AI agents?
Integrating Brevo with Vantegrate's AI agents means that an agent, such as the sales agent on WhatsApp, connects to your account through the Brevo v3 API and works with your real data: it creates and updates contacts, opens deals and moves them through your pipeline, and logs every conversation. The connection uses an API key dedicated to the integration, and the agent only uses the data the use case needs.
That is different from sending a campaign with a fixed template. Brevo gives you the marketing engine and a lightweight sales CRM, but it doesn't include an AI agent that understands and resolves the WhatsApp conversation: that's the layer Vantegrate adds. The agent checks the current data in your account and decides what to do with each lead. Your contact and conversation data stays in your Brevo: the agent reads and updates it, it doesn't take it anywhere.

What data moves between Vantegrate and your Brevo
The agent works on your contacts, your lists and Brevo's sales CRM in real time: it reads to answer, and logs every lead, deal and conversation where it belongs.
Contacts, lists and attributes
The agent creates and updates contacts with their attributes, adds them to the right lists and avoids duplicates with an upsert by phone, email or external ID.
Deals, tasks and notes
On the sales CRM, the agent opens a deal, moves it through your pipeline as the conversation moves forward, and leaves follow-up tasks and notes on the contact.
Conversations and events
Every WhatsApp chat is logged against the contact, and with Brevo webhooks a purchase or behavior event triggers a follow-up from the agent.
How the integration works, step by step
Vantegrate handles the setup and rollout. Your team authorizes, validates and starts using it.
Connection through the v3 API
We connect to the official Brevo API with an API key generated from your account. No scrapers, no admin login and no fragile bridges.
Data and templates
We define which contacts, attributes, lists and pipeline the agent uses, and we create the WhatsApp templates and submit them for Meta's approval.
Webhooks and the WhatsApp channel
We set up the webhooks that trigger the agent's workflows and the WhatsApp channel it answers on, inside the session window or with an approved template.
Validation with real data
We test with your real account and chats, validate with your sales and IT teams, and roll out in phases.
An AI agent versus a WhatsApp campaign in Brevo
Brevo adds WhatsApp as a channel: you send campaigns and transactional messages with Meta-approved templates and reply within the 24-hour window. What it doesn't include is an AI agent that answers, understands and resolves the conversation end to end: advanced automation is left to a third-party layer. That's exactly the gap Vantegrate's agent fills.
You can see the difference in every lead: the agent understands what the customer wants, asks the qualification questions that are still missing, creates or updates the deal and only escalates to a person when it's worth it. It works with live data from your account and logs every conversation against the contact, so nothing is left without follow-up.
| Dimension | WhatsApp campaign in Brevo | AI agent on Brevo |
|---|---|---|
| What it solves | Sending messages and campaigns | Answers and qualifies the conversation |
| Connection | Brevo editor | v3 API and webhooks |
| Context | Entered by a person | Live data on the contact and the deal |
| Qualification | Manual | Questions based on the conversation |
| Pipeline | A person moves it | Creates the deal and moves it through stages |
Comparison of patterns; the exact scope is defined with your team based on your account, your plan and your pipeline.
The first WhatsApp message you send needs a template: outside the 24-hour customer service window, WhatsApp requires a Meta-approved template, and the messages your business sends carry their own WhatsApp cost, which Meta charges per message according to its pricing, on top of Brevo's. The agent follows those rules: it replies free-form inside the session and uses a template to re-engage.

An agent connected to your Brevo vs. a standalone tool
| Standalone AI tool | Agent connected to your Brevo | |
|---|---|---|
| Data source | A copy that drifts | Your source of truth, live |
| Where your data lives | In a third-party system | In your environment, encrypted end to end |
| Result of each operation | Stuck in another app | Written back to your Brevo |
| Permissions and audit | Broad and hard to audit | Least-privilege scope and an audit trail |
| Reaching production | Often stalls as a pilot | Validated, phased rollout |
Why add an agent that answers leads on top of your Brevo
A third-party figure, with its published source, to size the context. It is not a Vantegrate result.

Sellium
Sales agent on WhatsApp: answers, qualifies and quotes with your account's data, opens deals and moves them through your pipeline, and logs every conversation against the contact.
Explore SelliumThe integration doesn't take your data anywhere
The principle is simple: AI comes to your data, not your data to the AI. The agent reads and updates your Brevo through the official API, with an API key dedicated to the integration, and the agents run on certified cloud infrastructure.
- Connection through the Brevo v3 API with an API key, with no scrapers and no fragile bridges.
- The agent reads and updates your contacts, lists and deals; your database stays in your Brevo account.
- The agent only touches the data the use case needs, with traceability of every operation.
- The agents run on Salesforce or Oracle Cloud Infrastructure, whose SOC 2 and ISO 27001 certifications belong to those platforms, not to Vantegrate or Brevo.

Does Brevo include an AI chatbot for WhatsApp?
Does Brevo include an AI chatbot for WhatsApp?
Not one that runs the conversation on its own. Brevo adds WhatsApp as a channel to send campaigns and transactional messages with Meta-approved templates and to reply within the session window, but it doesn't include an AI agent that answers and resolves the conversation. That layer of qualification and automatic replies is what Vantegrate's agent adds on top of your account.
How does the integration avoid duplicate contacts in Brevo?
How does the integration avoid duplicate contacts in Brevo?
The agent creates and updates contacts with an upsert: instead of creating a duplicate, it merges into the existing contact by phone, email or external ID. So when someone writes in on WhatsApp, their record in Brevo is updated with the latest interaction instead of generating a new one.
Why does the first WhatsApp message need a template?
Why does the first WhatsApp message need a template?
Two rules meet here. WhatsApp's: any message outside the 24-hour customer service window requires a Meta-approved template, while inside that window the agent replies free-form, with no template. And Brevo's: the first message you send through its API must carry a template ID. The messages your business sends on WhatsApp also carry Meta's cost, charged per message, on top of Brevo's.
Does my contact data leave Brevo?
Does my contact data leave Brevo?
The agent reads and updates your account through the API; it doesn't copy your database anywhere else. Your contacts, lists and conversations stay in your Brevo account, and access goes through an API key dedicated to the integration and is logged. The principle is that AI comes to your data, not your data to the AI.
