During June 2026, work focused on the centrapay-docs repository, where a new Patron Codes Retrieval API endpoint was developed using JavaScript. This endpoint enables retrieval of patron codes by namespace and external ID, enhancing the accuracy and flexibility of the patron code lookup process. The implementation included comprehensive integration testing to ensure reliability and seamless operation within existing systems. Documentation was updated in parallel to reflect the new API surface, maintaining clear traceability between code changes and documentation updates. The approach emphasized maintainability, with detailed commit messages supporting future audits and ongoing development in API development and integration workflows.
