Lars Hoidahl focused on enhancing operational API documentation and onboarding clarity for the RuterNo/adt-doc repository over a three-month period. He updated the vehicle sign-on flow documentation, aligning diagrams and descriptions with evolving system messages to reduce user friction. Lars introduced features such as BYPASS support for service deviations and an optional featureLevel parameter, enabling operators to communicate delayed starts and feature availability. He improved backoffice testing guidance, consolidating procedures and prerequisites for QA teams. Using Markdown and YAML, Lars applied technical writing and API documentation skills to deliver well-structured, maintainable documentation that improved integration reliability and supported cross-team collaboration.

Sep 2025 monthly summary for RuterNo/adt-doc: Delivered Operational API Enhancements focusing on client metadata and precise bypass semantics. Implemented an optional X-Client-Id header for API requests that does not affect authorization, and refined BYPASS deviation guidelines to indicate that specific calls within a journey may be bypassed by the operator. Updated API documentation accordingly with traceable changes tied to commit 8b17882cb25b07e834bccfb20fde2b4d304a1e4c. No major bugs fixed this month; emphasis on feature delivery and documentation improvements. Business value: improved client integration reliability, better observability, and clearer operator behavior. Technologies/skills demonstrated: API design, HTTP header usage, documentation, Git workflows, and cross-team collaboration.
