01 — Challenge

Siemens needed a production-ready connector to make the BuildingX IoT platform accessible to Mendix developers worldwide. The API was complex, documentation was limited and the connector had to meet enterprise quality standards.

02 — Approach

Started with a thorough analysis of the BuildingX REST API and OAuth authentication flow. Then built a layered Java implementation in Mendix with abstraction per API domain. Developed a complete sample application in parallel that demonstrates all use cases — so other developers can get started immediately.

03 — Result

A production-ready connector that's live in the Siemens ecosystem. Enterprise developers can integrate BuildingX functionality directly into their Mendix applications without needing to understand the underlying API.
