Official WhatsApp Business API or unofficial connectors: which to plug into your AI
Before automating WhatsApp there is one decision that conditions everything else: doing it through Meta’s official API or through unofficial connectors that emulate the app. The difference is not technical, it’s one of risk: one route is designed for businesses and the other can cost you your number.
The short answer: yes, it can be done. WhatsApp Business API has a public API and an AI agent can connect to it today so your WhatsApp calls and conversations are handled and logged without manual work. At Veltim we design and implement this integration: the first call is free and the quote is fixed. The rest of the article explains how.
The WhatsApp Business API (Cloud API) is Meta’s official route for a business to automate WhatsApp conversations: verified number, programmatic sending and receiving of messages, and approved templates for initiating conversations.
What the WhatsApp Business API allows
The Cloud API is public and documented by Meta: reception of messages via webhook in real time, replies within the conversation window, templates for notifications (appointment confirmed, order shipped) and multi-agent management on the same number.
That the API is public and documented matters more than it seems: it means the integration doesn’t depend on tricks or opaque connectors, but on an official contract the platform itself maintains. The full reference is in the WhatsApp Business API developer documentation.
What the WhatsApp Business API does well for this
On top of the official API we build the chatbot that handles, qualifies and schedules 24/7, coordinated with the voice agent: if a call is missed, the follow-up goes out via WhatsApp; if the customer writes, the conversation is recorded in your CRM. Appointment or order notifications use approved templates, with no risk of blocking.
The principle is always the same: the AI agent handles the conversation and the WhatsApp Business API just knows about it. No notes on paper to transfer later, no leads lost between the phone and the CRM.
Where this integration yields the most is in any business whose customers already message via WhatsApp: clinics, restaurants, shops and real estate agencies.
What you should know beforehand
Meta charges per conversation according to category and country, and templates require prior approval: messages must be designed with those rules in mind. Unofficial connectors skip both things... at the cost of risking number blocking, and with your number goes your customer channel.
To be clear: none of these points prevent the integration. They are design decisions we resolve before connecting anything, and that’s why the quote we give is fixed: the tool’s limits are already accounted for. The rule is design first and connect later: what records the agent creates, which it updates, and what remains always in the team’s hands.
Frequently asked questions
Can my existing WhatsApp number be connected?
Yes, an existing number can be migrated to the official API following Meta’s process, although its use changes: it stops living in the mobile app and is managed from the platform. We plan the migration so you don’t lose conversations during the switch.
How much does using the official WhatsApp API cost?
Meta invoices per conversation according to type (marketing, utility, service) and country, with rates published in its documentation. For a small business it is usually a lower cost compared to a missed call; we help you estimate it with your real volume.
Do I have to change tools to work with Veltim?
No. The integration is built on what you already use: the advantage of tools with a public API like WhatsApp Business API is precisely that they don’t force any migration.
Who does this integration and how much does it cost?
The integration is designed and implemented by Veltim, an AI automation agency from Madrid that works remotely across Spain. The price depends on your volume and what needs to be connected: in a free call we review your WhatsApp Business API account and give you a fixed quote with concrete deadlines.
