During April 2026, this developer enhanced the tapdata/tapdata repository by implementing OAuth2 Token Endpoint JSON support, allowing the platform to accept JSON-formatted requests for token issuance alongside the traditional form-urlencoded flow. The solution introduced the OAuth2JsonSupportFilter, ensuring backward compatibility while broadening integration options for clients using modern authentication standards. Working primarily with Java, Docker, and YAML, the developer focused on API development and CI/CD practices to deliver this feature as part of release v4.17.0. This update reduced integration friction, improved interoperability for JSON-based OAuth clients, and strengthened the authentication flow without introducing breaking changes.
