Worked on the keycloak/keycloak repository to enhance Push Authorization Requests (PAR) handling within the OIDC flow. Addressed a critical issue by relaxing the mandatory validation of the request_uri parameter, which previously blocked valid PAR flows and complicated client onboarding. The solution involved backend development in Java, removing redundant checks and simplifying request parsing logic. Integration testing was added to ensure correct PAR processing when request_uri is configured as a requirement, improving reliability for PAR-enabled clients. This work demonstrated a focus on code quality, thorough testing, and alignment with product requirements, ultimately supporting smoother interoperability in OIDC deployments.
