2025-09 monthly summary for totvs/winthor-smart-hub-layouts. Delivered External System Data Integration and API/Route Enhancements to improve cross-system data correlation and data handling. Implemented idExterno and tipoIdInterno for robust data linkage, refreshed route naming for clarity, updated API endpoints and JSON structures, and enhanced the WTA - BUSCAR ESTOQUE route with a CALLORIGIN parameter to support origin-aware data retrieval. Fixed a duplicate URL generation issue by correcting the URL creation/management logic to ensure uniqueness and prevent inconsistencies. These changes significantly improve data reliability, traceability, and cross-system workflows, enabling more accurate dashboards and scalable integrations. Technologies demonstrated include API design and data modeling (idExterno, tipoIdInterno, CALLORIGIN), route architecture, JSON schema evolution, version control, and cross-system integration.
