## Key Components

| Component | Description |
|-----------|-------------|
| **API Gateway** | Entry point, authentication |
| **Microservices** | Product-specific services |
| **Webhooks** | Event notifications |

## Integration Patterns

- **Synchronous**: Request/response
- **Asynchronous**: Webhooks for events
- **Batch**: Bulk operations

## Best Practices

- Implement retry logic
- Handle webhooks idempotently
- Use correlation IDs
- Log all transactions
