How to Use WhatsApp Business API for Marketing?

WhatsApp Business API is built for businesses that want to scale communication and automate customer interactions. Unlike the WhatsApp Business App, which is suitable for small businesses, the API supports advanced features like automation, CRM integration, and multi-agent access. This makes it ideal for high-volume messaging, real-time support, and structured WhatsApp marketing campaigns.

The Role of Business Solution Providers (BSPs)

To access the WhatsApp Business API, businesses must work with a Business Solution Provider (BSP). BSPs offer the infrastructure, compliance setup, and technical tools needed to integrate the API into existing systems. They handle everything from message template approvals to policy enforcement, reporting, and analytics. Sanoflow is a Meta Verified BSP, providing a complete suite of tools to manage WhatsApp marketing, sales, and support, from automation to campaign insights.
