What is WhatsApp Business API?

The WhatsApp Business API is an enterprise solution that lets businesses communicate with customers at scale on WhatsApp. Unlike the WhatsApp Business app (designed for small businesses), the API provides:
  • Programmatic access to send and receive messages
  • Support for multiple agents and team collaboration
  • Integration with existing business systems (CRM, helpdesk, etc.)
  • Template-based messaging for notifications and marketing
  • Webhook support for real-time event processing
  • Unlimited message volume (within WhatsApp’s rate limits)

​
Reach 2+ Billion Users

WhatsApp has over 2 billion active users worldwide, making it one of the most effective channels for customer engagement. WhatsApp messages have a 98% open rate - significantly higher than email or SMS.

​
