This course covers the OWASP API Security Top 10, authentication vulnerabilities, rate limiting bypasses, mass assignment flaws, broken object-level authorization (BOLA/IDOR), and advanced injection techniques specific to APIs. You'll use tools like Postman, Burp Suite, MITMProxy, ffuf, and Arjun to enumerate, analyze, and exploit API endpoints in hands-on labs.
Upon completion, you'll be equipped for roles such as API Security Tester, Bug Bounty Hunter, and Application Security Engineer. You'll be capable of conducting thorough API security reviews and producing professional reports for clients and organizations.
Chapter 1 : What Are APIs and Why They Matter
Chapter 2 : REST, GraphQL, SOAP, and gRPC Fundamentals
Chapter 3 : API Security Testing Methodology
Chapter 4 : Setting Up API Testing Environment (Postman, Burp, MITMProxy)
Chapter 5 : API Documentation Analysis (Swagger, OpenAPI)

Filled a huge gap in my security knowledge
I was already doing web pentesting but had no idea how deep API vulnerabilities go. The BOLA and JWT attack modules completely changed my perspective on modern application security.

Incredible depth on OWASP API Top 10
The course walks through every OWASP API vulnerability with real lab exercises. I found three BOLA bugs on a bug bounty program within a week of finishing the course.

Very practical and career-focused
Great course for anyone moving into modern application security. The GraphQL security module is something I haven't seen covered this thoroughly anywhere else.
