To test REST and GraphQL APIs for authentication and authorization flaws, you need to systematically verify API keys, JWTs, OAuth flows, and check object-level access control and multi-tenant isolation. This process uncovers role boundary vulnerabilities before deployment.

Auditing GraphQL introspection, depth, and complexity protections involves probing the API to ensure it rejects malicious queries and restricts schema exposure. This validates that GraphQL-specific protections prevent resource exhaustion and data extraction attacks.

Fuzzing API parameters to find input validation and injection vulnerabilities requires sending malformed and unexpected data to endpoints. This systematically identifies how the API handles invalid input, probing for injection flaws and sanitization gaps.

Yes, you can use this API security testing workflow for bug bounty assessments and release readiness checks. It applies systematic endpoint discovery, access control testing, and rate limit verification to document vulnerabilities and remediation gaps for API-based services.

Yes, API security testing checks rate limiting and error handling to resist brute-force abuse. It verifies that endpoints properly implement rate limits and sanitize error messages, confirming the API resists unauthorized access and systematic probing.
