Developed support for the OpenAPI HTTP Bearer security scheme in the MagaluCloud/magalu repository, enabling proper definition and handling of HTTP Bearer token authentication within API specifications. This work involved introducing a dedicated httpbearer constant and integrating it into the set of supported security schemes, ensuring alignment with OpenAPI standards. Leveraging Go for backend and API development, the implementation improved the security posture and interoperability of the API by facilitating consistent, token-based authentication. The changes were tracked through commit-based workflows, demonstrating attention to codebase maintenance and specification compliance while enhancing the developer experience for client integrations and secure API access.
