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

Process images for web development — resize, crop, trim whitespace, convert formats (PNG/WebP/JPG), optimise file size, generate thumbnails, create OG card images. Uses Pillow (Python) — no ImageMagick needed. Trigger with 'resize image', 'convert to webp', 'trim logo', 'optimise images', 'make thumbnail', 'create OG image', 'crop whitespace', 'process image', or 'image too large'.
