WhatsApp QR vs WhatsApp Business API
Overview
Two connection methods are available for WhatsApp integration on Resayil's platform:
WhatsApp QR Connector uses QR code scanning to connect existing personal or business WhatsApp numbers. The phone must remain online, and the connection mirrors your device's WhatsApp activity through a dedicated worker service.
WhatsApp Business Cloud API (WABA) is Meta's official cloud-hosted business solution requiring no physical device. It offers enterprise-grade features and professional verification without phone dependency.
Key Differences
Connection & Setup
- QR: Requires QR scan; phone must stay connected
- WABA: Uses OAuth authentication; no phone needed
Messaging Capabilities
WhatsApp QR supports basic messaging (text, media, contact cards, locations, groups, channels). Cloud API adds advanced features including interactive buttons, list messages, template messages, WhatsApp Flows, and payment integration.
Performance & Limits
- QR: 1-20 messages/minute; subject to anti-spam detection
- WABA: 60+ messages/second; tier-based limits from 1,000 to unlimited users per 24 hours
Business Features
Only Cloud API provides business verification with a green checkmark, official account status, quality ratings, and full catalog/shopping integration.
Reliability
Cloud API offers 99.9% uptime SLA with no device dependency. QR connectivity depends on phone availability and may require periodic QR rescanning.
Pricing
"WhatsApp QR: Free messaging" beyond platform subscription. "Cloud API includes conversation-based pricing from Meta" with free tier of 1,000 monthly conversations.
Best Use Cases
Choose QR for: Small businesses, limited budgets, <500 daily messages, quick setup
Choose Cloud API for: Enterprise needs, high-volume messaging, marketing campaigns, regulated industries, e-commerce integration
Migration Options
Users can migrate from QR to Cloud API while preserving chat history, or enable coexistence mode with WhatsApp Business App simultaneously.
