Integrate WhatsApp with AI agentson Meta's official API

With the official WhatsApp Business Platform as the channel and your CRM as the destination: the agent answers each conversation, reads live data from your system to reply and logs the outcome (lead, opportunity, case). Vantegrate sets up your number on the official API and connects it to your CRM; your team operates the channel and signs off. WhatsApp is the native channel of the whole Vantegrate suite. The CRM-specific details are in WhatsApp and Salesforce integration and WhatsApp and HubSpot integration.

Because unofficial automation tools put the account at risk of a ban: they hook into WhatsApp through means Meta doesn't authorize. The WhatsApp Business API is the official channel, stable and with a verified business identity, and it keeps compliance in order (opt-in, approved templates, opt-out). It's the foundation Vantegrate's agents run on. If your team answers from the WhatsApp Business app, see migrating from WhatsApp Business to the official API.

Meta charges per delivered message, with rates that vary by the recipient's country and the category (marketing, utility, authentication, service). For a US number, a utility or service message is billed at $0.0034 on Meta's rate card, and each number gets 1,000 free service messages per month. Rates change often: the details and caveats are in our guide to WhatsApp Business API cost.

Not with marketing templates: Meta doesn't deliver them to US (+1) numbers, according to its developer documentation. Utility and authentication templates, replies within the customer service window and conversations that start from a click-to-WhatsApp ad still work, and messages in that ad window aren't charged for 72 hours. The limit follows the recipient's number, so customers with numbers outside the US, such as your buyers in Mexico, can still receive marketing templates within Meta's per-user limits. For a campaign to US numbers you need another channel, such as SMS or RCS through Twilio.

Yes, when the agent has a business task. Meta's terms for the WhatsApp Business Platform prohibit offering a general-purpose AI assistant as the main function, while bots built for support, bookings, order tracking or sales remain allowed (respond.io). Each Vantegrate agent is built for one business job (selling, re-engaging customers, processing documents or answering questions about your data) and works on your own systems, not as an open-ended assistant.

In your CRM: even though the channel is Meta's official API, your system remains the source of truth. Every conversation is logged on the matching record with its summary and campaign attribution, so the data isn't trapped in a separate messaging tool and your team works from complete information.

The agent hands off to a person and passes along the conversation with the context already gathered, so the sales rep doesn't start by asking what the customer already answered. You define the handoff rules with us: an explicit request from the customer, the type of inquiry or business hours. More in handing off to a sales rep.

The number and the WhatsApp Business account are yours, not Vantegrate's. If you stop working with us, the agent's access is revoked and your team keeps running the channel. The conversation history stays where you were already logging it: your CRM.
