What Is WhatsApp Business API? Key Features for Developers
The WhatsApp Business API enables businesses to automate messaging, integrate with CRM systems, and scale customer support. Unlike the WhatsApp Business App (for small businesses), the API is built for high-volume operations and deep system integration.
Core Features:
- Automation & Chatbots: Automate responses and customer journeys.
- CRM Integration: Sync WhatsApp with your backend or customer management tools.
- Bulk Messaging: Send out notifications, alerts, and marketing messages at scale.
- Multi-Agent Support: Multiple team members can manage conversations simultaneously.
The API is not a standalone app—deployment requires backend setup and hosting (either on your own server or via Meta’s Cloud API).
WhatsApp Business API Pricing: What’s Free and What’s Not?
WhatsApp Business API uses a conversation-based pricing model. Businesses are charged per 24-hour conversation thread, but each WhatsApp Business Account gets 1,000 free service conversations per month. Beginning November 1, 2024, all service conversations will be completely free, allowing businesses to interact with customers at no charge for these support scenarios.
Conversations initiated via Facebook Page call-to-action buttons or WhatsApp ads are also free for 72 hours.
