## Technical Specifications

### Database Requirements

- **ERPNext**: v13.0 or higher
- **Frappe Framework**: v13.0 or higher
- **MySQL**: 5.6 or higher
- **Python**: 3.6 or higher

### Performance Considerations

- **Inventory Sync**: O(n) where n = number of modified items
- **Customer Sync**: O(1) per customer with indexed lookups
- **Log Queries**: Optimized with compound indexes on integration + status
- **Scheduling**: Minimal overhead with timestamp-based gating

### Security Features

- Credential storage through Frappe's password manager
- API token encryption at rest
- Role-based access control on logs
- Audit trail for all configuration changes

### Scalability

- Support for high-volume item catalogs (100,000+ items)
- Batch processing for inventory updates
- Queue-based job execution for long-running tasks
- Horizontal scaling for multi-instance deployments

## Best Practices

### Error Handling

```python
try:
    result = api_call()
    create_log(
        integration="Provider",
        method="api_call",
        status="Success",
        response_data=result
    )
except Exception as e:
    create_log(
        integration="Provider",
        method="api_call",
        status="Failed",
        message=str(e),
        traceback=frappe.get_traceback()
    )
```

### Configuration Validation

```python
def validate_settings(settings):
    if not settings.is_enabled():
        raise Exception("Integration is disabled")
    
    if not settings.get_erpnext_warehouses():
        raise Exception("No warehouses configured")
    
    if not settings.api_endpoint:
        raise Exception("API endpoint not configured")
```

### Testing Strategy

```python
# In provider_integration/tests/test_provider.py
from ecommerce_core.utils.before_test import before_tests

def test_inventory_sync():
    before_tests()  # Sets up test environment
    
    settings = get_test_settings()
    inventory = get_inventory_levels(
        settings.get_erpnext_warehouses(),
        "Provider"
    )
    
    assert len(inventory) > 0
    assert inventory[0].actual_qty >= 0
```
