During December 2024, this developer enhanced the MewsSystems/gitbook-connector-api repository by extending the API schema to support Spanish Identity Documents. The work focused on adding the IdentityDocumentSupportNumber field to both request and response schemas, enabling more comprehensive data capture and improved eligibility checks in compliance with Spanish regulations. The implementation involved careful API design, schema evolution, and commit-based change tracking, with all changes documented in Markdown. By concentrating on a single, well-defined feature and maintaining clear traceability, the developer improved data quality for identity processing and streamlined onboarding workflows for Spanish-ID use cases without introducing new bugs.
