Technical Specification

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

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

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

# 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
