What is WhatsApp Business API? Complete Guide

What is WhatsApp Business API?

WhatsApp Business API is a programmatic interface that allows medium and large businesses to communicate with customers at scale through WhatsApp. Unlike the free WhatsApp Business App, the API enables integration with business systems, automation, and high-volume messaging.

WhatsApp Business API vs. WhatsApp Business App

How WhatsApp Business API Works

1. Access Through Partners

WhatsApp doesn't provide API access directly. Businesses must use:

• Business Solution Providers (BSPs): Official Meta partners (like Hyperleap)
• Cloud API: Direct Meta-hosted solution

2. Message Types

Business-Initiated Messages (Templates):

• Pre-approved message formats
• Used for notifications, updates, alerts
• Require Meta approval
• Incur charges per conversation

User-Initiated Messages:

• Responses to customer messages
• Free-form conversation (24-hour window)
• Lower cost than business-initiated

3. Conversation-Based Pricing

WhatsApp charges per 24-hour conversation window:

Note: First 1,000 service conversations/month are free.
