## What is WhatsApp Coexistence?

WhatsApp Coexistence allows microbusinesses to use both the WhatsApp Business mobile app and WhatsApp Cloud API simultaneously on a single phone number. This provides the best of both worlds: manual messaging flexibility with enterprise-grade automation.

## Technical Architecture

### Bidirectional Synchronization
- Messages sent from the mobile app appear in your Cloud API webhook
- Messages received via Cloud API appear in the mobile app
- Enabled via `smb_message_echoes` webhook field

### Message Flow
1. Customer sends message to business number
2. Message delivered to both mobile app AND Cloud API webhook
3. Business can respond from either interface
4. All messages synchronized across platforms

## Throughput Limits

| Mode | Throughput | Use Case |
|------|------------|----------|
| Coexistence | 5 MPS | Microbusiness, manual + automation |
| Standard Cloud API | 80-100 MPS | Enterprise, full automation |
