WhatsApp Business API for Enterprise
WhatsApp Business API enables enterprises to communicate with customers at scale through the world's most popular messaging platform. With 2 billion+ users globally and 98% message open rates, WhatsApp is the highest-engagement messaging channel available.
Setup and Configuration
Business Account Verification
Complete Meta Business Verification to obtain a green checkmark badge. Verified accounts have higher messaging limits and greater customer trust.
Phone Number Selection
Dedicate a phone number exclusively for WhatsApp Business. This number cannot be used for regular WhatsApp messaging. Use a landline or VoIP number if needed — WhatsApp supports these with voice call verification.
Messaging Limits
Unverified accounts: 250 messages/day. Verified accounts scale to 1,000 → 10,000 → 100,000 messages/day based on quality rating and volume history.
Template Message Management
Template Categories
- Utility: Order confirmations, shipping updates, appointment reminders
- Authentication: OTPs, account verification codes
- Marketing: Promotional offers, product announcements, newsletters
Approval Process
Submit templates through Meta Business Manager. Templates are reviewed within 24-48 hours. Use clear, non-deceptive language. Avoid excessive capitalization, urgency manipulation, or misleading content.
Template Variables
Use numbered placeholders ({1}, {2}, {3}) for dynamic content. Variables cannot be used in header or footer components — only in the body text.
Two-Way Communication
Session Messages
After a customer sends you a message, you have a 24-hour session window to reply with free-form messages (no template required). Use this window for customer support conversations.
Quick Replies
Offer predefined response options to customers. Quick replies reduce friction and guide conversations toward resolution.
Interactive Messages
Use list messages and button messages to present structured choices. These have significantly higher response rates than plain text prompts.
Best Practices
- Respond within the 24-hour session window to avoid template message costs
- Use utility templates for transactional messages and marketing templates for promotions
- Monitor quality rating — dropping below "medium" reduces messaging limits
- Implement opt-in flows before initiating conversations
- Use rich media (images, documents, locations) to increase engagement
