A workflow for testing REST and GraphQL API security covering endpoint discovery, authentication, authorization, rate limiting, and input validation.

About

A phased security-testing workflow for APIs that enumerates endpoints and tests auth, JWT/OAuth flows, rate limiting, and input validation. A developer or bug-bounty tester uses it to assess REST and GraphQL endpoint security.

  • Phased flow from API discovery through authentication testing
  • Routes to companion skills like api-fuzzing and broken-authentication

API Security Testing Workflow

Overview

Specialized workflow for testing REST and GraphQL API security including authentication, authorization, rate limiting, input validation, and API-specific vulnerabilities.

When to Use This Workflow

Use this workflow when:

  • Testing REST API security
  • Assessing GraphQL endpoints
  • Validating API authentication
  • Testing API rate limiting
  • Bug bounty API testing

Workflow Phases

Phase 1: API Discovery

Skills to Invoke
  • api-fuzzing-bug-bounty - API fuzzing
  • scanning-tools - API scanning
Actions

1. Enumerate endpoints 2. Document API methods 3. Identify parameters 4. Map data flows 5. Review documentation

Copy-Paste Prompts
Use @api-fuzzing-bug-bounty to discover API endpoints

Phase 2: Authentication Testing

Skills to Invoke
  • broken-authentication - Auth testing
  • api-security-best-practices - API auth
Actions

1. Test API key validation 2. Test JWT tokens 3. Test OAuth2 flows 4. Test token expiration 5. Test refresh tokens

Copy-Paste Prompts
Use @broken-authentication to test API authentication

Phase 3: Authorization Testing

Skills to Invoke
  • idor-testing - IDOR testing
Actions

1. Test object-level authorization 2. Test function-level authorization 3. Test role-based access 4. Test privilege escalation 5. Test multi-tenant isolation

Copy-Paste Prompts
Use @idor-testing to test API authorization

Phase 4: Input Validation

Skills to Invoke
  • api-fuzzing-bug-bounty - API fuzzing
  • sql-injection-testing - Injection testing
Actions

1. Test parameter validation 2. Test SQL injection 3. Test NoSQL injection 4. Test command injection 5. Test XXE injection

Copy-Paste Prompts
Use @api-fuzzing-bug-bounty to fuzz API parameters

Phase 5: Rate Limiting

Skills to Invoke
  • api-security-best-practices - Rate limiting
Actions

1. Test rate limit headers 2. Test brute force protection 3. Test resource exhaustion 4. Test bypass techniques 5. Document limitations

Copy-Paste Prompts
Use @api-security-best-practices to test rate limiting

Phase 6: GraphQL Testing

Skills to Invoke
  • api-fuzzing-bug-bounty - GraphQL fuzzing
Actions

1. Test introspection 2. Test query depth 3. Test query complexity 4. Test batch queries 5. Test field suggestions
