Meta-Verified WhatsApp Business Solution Provider
Apply, verify and go live on the official WhatsApp Business API with Defuser as your BSP — then layer agentic AI, broadcasts and a unified inbox on top.
The WhatsApp Business API is Meta's official platform for medium and large businesses to message customers at scale — far beyond what the free WhatsApp Business app allows. It has no chat interface of its own; instead you connect it through a Business Solution Provider (BSP) like Defuser, which gives you the inbox, automation, broadcasting and analytics on top.
With the API you can send four message types — Authentication (OTPs), Utility (order and account updates), Marketing (promotions) and Service (replies within a customer-care window) — to large audiences, with multiple agents, full automation and compliance baked in.
From application to your first message in three steps.
Start with Defuser as your Meta-Verified BSP. We walk you through Meta Business verification and display-name approval.
Use a new number or migrate your existing one. We provision the API and link it to your Defuser workspace.
Build flows with Talksy, set up broadcasts and open your unified inbox — then start messaging compliantly at scale.
Verification requirements, local adoption and Meta's per-conversation rates differ by market, so we publish dedicated guides for each. Start with WhatsApp Business API in India, the UAE or Pakistan — and we also cover Saudi Arabia, Brazil, Indonesia, Nigeria and Mexico, with more countries added regularly.
Whichever market you're in, you can see exact pricing for your country — including Meta's conversation fees — in our 30+ country pricing calculator before you commit.
Guided Meta Business verification and display-name approval so you go live without the usual back-and-forth.

Layer AI that answers, qualifies and converts directly on your API number.
Send marketing and utility templates to segments at scale, within Meta's rules.

If you're outgrowing the free app — too many chats for one phone, a team that needs a shared inbox, or a need to broadcast and automate at scale — the API is your next step. It powers everything from WhatsApp marketing to automated notifications and full conversation management.
A BSP is a Meta-approved partner that gives you access to the WhatsApp Business API plus the software around it — inbox, automation, broadcasts and analytics. Defuser is a Meta-Verified BSP, so you get verified access and the platform in one place.
Most businesses get verified and start sending within a few days, depending on how quickly Meta Business verification and display-name approval complete. We guide you through every step to avoid delays.
