What is the WhatsApp Business API?

It is Meta’s official interface for businesses to message customers on WhatsApp at scale. Unlike the free WhatsApp Business app, it supports several agents on one number, approved message templates, bulk campaigns, chatbots and integrations with your own software.

How do I get the WhatsApp Business API?

You connect a phone number to the WhatsApp Business Platform through a Meta Business account, usually via a platform such as Scale360x Engage. Approval timing depends on Meta. Engage guides you through connecting the number and gives you the inbox and tools to use it.

How much does the WhatsApp Business API cost?

Two costs apply: Meta charges per delivered message under its own rate card, billed from your Meta account to Meta (each number also gets a monthly free tier of service replies), and the platform charges a subscription. Engage plans start at ₹999 a month and Meta’s charges are never marked up.

Can I keep using my existing WhatsApp number?

A number can be used once it is registered on the Business Platform. Moving it off the regular WhatsApp app disables it there, so plan for that first.

Is there a free trial?

Yes. Every new workspace gets a 7-day free trial with no card, including 10 AI credits.

WhatsApp Business API platform

Get the official WhatsApp Business API with a shared inbox, campaigns, chatbots and AI on top. Connect your Meta Business number, start a 7-day free trial, no card.

The WhatsApp Business API (the WhatsApp Business Platform) is how a company sends and receives WhatsApp messages at scale: more than one person on a number, approved templates, campaigns, chatbots and your own systems. Meta does not give you a screen for it. You need a platform on top.

Scale360x Engage is that platform. You connect your own number through your own Meta Business account, and get a shared team inbox, broadcast campaigns, no-code chatbots, an AI assistant, drip sequences, a REST API and signed webhooks in one workspace. Meta bills you directly for messages; Engage never marks that up.

Official API, no workarounds

Your number runs on the WhatsApp Business Platform through your own Meta account, so there is no unofficial gateway that can get the number banned.

Shared inbox for the whole team

Many people reply from one number, with assignment, private notes and delivery and read status.

Everything on top of the API

Campaigns, chatbots, AI assistant, drip sequences, contacts and templates are built in. Nothing extra to buy and stitch together.

REST API and webhooks

Send messages from your own product and get signed, retried webhooks when a customer replies. Included on Pulse and Orbit.
