WhatsApp API Integration

What this is, in plain words

Your customers already live on WhatsApp. Running your business from one phone, though, means lost chats, no history and no way to share the load. The official WhatsApp Business API fixes that.

We set up the Cloud API on a verified number, get your message templates approved and connect it to your CRM, store or booking system. Your team shares one inbox, bots handle the simple questions and customers get updates the moment something changes.

What you get

Built for results you can see

  • One number, whole team

    Several people answer from the same business number, with full history.

  • Updates customers read

    Order, booking and payment updates arrive where customers actually look.

  • Faster sales

    Send a payment link in the chat and close the sale right there.

  • Campaigns that reach

    Approved broadcasts go to opted in customers without getting your number blocked.

FAQ

WhatsApp API: common questions

Can we keep our current WhatsApp number?

Usually yes, but it must be removed from the regular WhatsApp app first. We explain the steps and options before moving it.

Do we pay Meta separately?

Yes. Meta charges per conversation based on type and country, billed to your own Meta account. We help you plan for it.

Can we send bulk messages?

You can send approved template messages to customers who opted in. This keeps your number in good standing.

Who owns the number and the setup?

The number and Meta account are always yours. After final payment the code and integrations are yours too, unless we agree otherwise.

Do you support it after launch?

Yes. We offer monthly support for hosting, template changes, new flows and Meta policy updates.
