During September 2025, this developer enhanced the Smartling/api-docs repository by delivering a new feature for the Strings API, introducing flexible POST endpoints that allow retrieval of source strings and translations using hashcodes and file URIs in the request body. The work focused on improving localization workflows and developer experience by enabling more dynamic and precise data access. Utilizing YAML and OpenAPI for API documentation, the developer ensured that the updated endpoints were clearly documented, supporting better onboarding and integration accuracy. This contribution strengthened change traceability and aligned documentation, laying a foundation for future API growth and streamlined localization processes.
