When to use

• Testing API endpoints for authorization flaws, injection vulnerabilities, and business logic bypasses
• Assessing the security of microservices architecture where APIs are the primary communication method
• Validating that API gateway protections (rate limiting, authentication, input validation) are properly enforced
• Testing third-party API integrations for data exposure and insecure configurations
• Evaluating GraphQL APIs for introspection disclosure, query complexity attacks, and authorization bypasses

When not to use

• APIs without written authorization
• Load testing
• Denial-of-service testing unless explicitly scoped
