Identify publicly documented API bug bounty targets to map the API attack surface, including unauthenticated requests, IDOR, SSRF, and inventory mismanagement.
Understand how a rest api enables client–server communication through endpoints, methods like get info, and parameters such as photo id, with responses in json.
Examine use cases for Rest, Soap, and GraphQL APIs across social media, e-commerce, IoT, and enterprise contexts, noting Rest's popularity in social platforms and GraphQL's rising adoption.
Set up a practical API testing lab in Docker using Vapi to practice security test cases and explore the top ten API risks.
Identify broken object level authorization in the first api, where attackers access other users' data by manipulating requests, illustrating OWASP’s guidance on access control failures.
Import Postman environment files and collections, set the host variable to the app's target IP on your Ubuntu instance, and save and enable the configuration.
Explore excessive data exposure in APIs and mobile apps, learn how missing rate limiting enables brute-force OTP attacks, and review real-world bug bounty payouts for account takeover findings.
Learn how mass assignment can grant admin privileges or credits via crafted API requests. Explore insecure cross-origin resource sharing and how star, null, or evil.com headers enable data exposure.
Demonstrate converting messy JSON data into a beautified, searchable format using the grown tool and a JSON beautifier, contrasting non-beautified and beautified outputs.

Welcome to the Mastering API Security course!
This course is designed for cybersecurity professionals and developers who want to secure APIs from real-world attacks. With the rise of API-driven applications, securing APIs has become a critical skill in the cybersecurity industry.
This course is not just about theory—it is highly practical and includes real-world API attacks and security measures. We will focus on hands-on exploitation, security testing, and mitigation strategies to protect APIs effectively.
You will start with The fundamentals of APIs and their Security Risks, moving step-by-step towards advanced attack techniques and secure coding practices. Unlike other API security courses that focus only on theoretical concepts, this course includes LIVE API security testing scenarios to prepare you for real-world challenges.
Throughout the course, you will:
Learn the OWASP API Security Top 10 vulnerabilities and how to exploit them.
Use tools like Burp Suite, Postman, and OWASP ZAP for API pentesting.
Secure APIs with OAuth 2.0, JWT, API Keys, and Rate Limiting.
Perform API hacking techniques, including BOLA, mass assignment, and token manipulation.
Explore real-world case studies of API breaches and learn from them.
Understand how AI is being used in API security for both attacks and defense.
Learn how to integrate API security into DevSecOps and CI/CD pipelines.
This course is highly practical and includes hands-on labs to help you master API security. Whether you are a Pentester, Security Engineer, Developer, or Bug Bounty Hunter, this course will give you the skills to protect modern web applications from API-based attacks.
