# 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

#### Copy-Paste Prompts
```
Use @api-fuzzing-bug-bounty to test GraphQL security
```

### Phase 7: Error Handling

#### Skills to Invoke
- `api-security-best-practices` - Error handling

#### Actions
1. Test error messages
2. Check information disclosure
3. Test stack traces
4. Verify logging
5. Document findings

#### Copy-Paste Prompts
```
Use @api-security-best-practices to audit API error handling
```
