• Test API version migrations, deprecations, and regression scenarios for updated endpoints.
• Use API testing tools (Postman, SoapUI, ReadyAPI, or similar) to execute automated and manual test suites.
• Validate payloads, schema enforcement, authentication behavior, and token flows (OAuth2, SSO).
• Reproduce and document API defects, integration failures, and unexpected service responses.
• Maintain API test artifacts, results, regression reports, and traceability documentation.
• Collaborate with developers, integration engineers, and cybersecurity teams on test outcomes and mitigation actions.
