# API Security Router This is the routing entry point for API security testing. Use this skill first to decide whether the API issue is mostly recon/docs, object authorization, token trust, or GraphQL/hidden parameters, then route to a deeper topic skill. ## When to Use - The target exposes REST APIs, mobile backends, or GraphQL endpoints - You need to define API testing order before going into specific topics - You want to handle object authorization, JWT, GraphQL, and hidden fields as separate tracks ## Skill Map - [API Recon and Docs](../hack-api-recon-and-docs/SKILL.md): OpenAPI, Swagger, version drift, hidden documentation - [API Authorization and BOLA](../hack-api-authorization-and-bola/SKILL.md): BOLA, BFLA, method abuse, hidden writable fields - [API Auth and JWT Abuse](../hack-api-auth-and-jwt-abuse/SKILL.md): bearer token, header trust, claim abuse, rate-limit bypass - [GraphQL and Hidden Parameters](../hack-graphql-and-hidden-parameters/SKILL.md): introspection, batching, undocumented fields, hidden parameters ## Quick Triage | Observation | Route | |---|---| | Swagger or OpenAPI is present | [api-recon-and-docs](../hack-api-recon-and-docs/SKILL.md) | | IDs appear in URL, JSON, headers, or GraphQL args | [api-authorization-and-bola](../hack-api-authorization-and-bola/SKILL.md) | | JWT token visible in traffic | [api-auth-and-jwt-abuse](../hack-api-auth-and-jwt-abuse/SKILL.md) | | `/graphql` or batched JSON arrays are present | [graphql-and-hidden-parameters](../hack-graphql-and-hidden-parameters/SKILL.md) | | Registration, login, or profile updates accept extra fields | [api-authorization-and-bola](../hack-api-authorization-and-bola/SKILL.md) then [api-auth-and-jwt-abuse](../hack-api-auth-and-jwt-abuse/SKILL.md) | ## Recommended Flow 1. Start with exposed endpoints and documentation assets 2. Then evaluate object-level and function-level authorization 3. Then evaluate token, header, signature, and rate-limit boundaries 4. If GraphQL or complex JSON is present, continue with hidden fields and schema abuse ## Related Categories - [auth-sec](../hack-auth-sec/SKILL.md) - [business-logic-vuln](../hack-business-logic-vuln/SKILL.md) - [recon-for-sec](../hack-recon-for-sec/SKILL.md)
