What Is WhatsApp Business API?

WhatsApp Business API is Meta's official solution that lets medium and large businesses connect WhatsApp to their own systems, like a CRM or shared team inbox, so multiple team members can send and receive messages and automate replies at scale. Unlike the free WhatsApp Business App, it has no standalone interface — you need a platform like oChats to use it.

How WhatsApp Business API Works

The API itself is just a messaging pipe — it sends and receives WhatsApp messages programmatically, but it has no inbox, no team login, and no chatbot builder on its own. That's why every business using it connects to a platform (like oChats) that provides the actual dashboard: a shared team inbox, contact management, automation, and reporting sit on top of the raw connection.

Messages sent this way are billed per conversation by Meta, based on who starts the conversation (business-initiated vs. customer-initiated) and the recipient's country — this fee is separate from whatever platform subscription you use. See the oChats pricing breakdown for the current rate card.

How to Get WhatsApp Business API

Choose a platform (BSP or provider) — you can't apply for direct access as an individual business in most cases; you go through a Business Solution Provider or platform like oChats that has direct access to Meta's infrastructure.
Verify your business — Meta requires a verified Facebook Business Manager account and business details (name, address, website) matching your official registration.
Register your number — this must be a number not currently active on regular WhatsApp or WhatsApp Business App, since it becomes dedicated to this connection.
Get your business profile approved — Meta reviews your business name and profile before granting a green checkmark (official verification), though it works before this approval too.

How to Set It Up

Sign up with your chosen platform — for oChats, this starts with a 7-day free trial request.
Connect your number — the platform walks you through linking your verified number.
Set up your team inbox — invite team members, assign conversations, and configure quick replies.
Build automation (optional) — set up a chatbot or autoreply flow for common questions using a no-code builder.
Go live — start sending and receiving messages through your connected number.

Frequently Asked Questions

The API access itself has no separate licensing fee from Meta, but you do pay two things in practice: a platform subscription (like oChats, starting at US$359/year) to actually use it through a dashboard, and per-conversation fees billed by Meta based on conversation type and country.

Number registration and basic access is typically fast, often within a day or two through a platform provider. Full business profile verification (the green checkmark) can take longer, from a few days to a few weeks, since Meta reviews your business details manually.

Yes, in most cases, but the number must be removed from the regular WhatsApp app or WhatsApp Business App first, since a number can only be active on one WhatsApp product at a time.

No, not if you use a platform like oChats. The raw API is developer infrastructure, but platforms built on top of it provide a no-code dashboard, team inbox, and chatbot builder so non-technical teams can use it directly.
