Burp Extender API Development for Beginners

Web application security testing often requires custom automation and tailored tools that off-the-shelf scanners cannot provide. This text-based course guides you through the foundational concepts of the Burp Extender API, enabling you to write your own custom extensions to automate tasks and analyze traffic. You will transition from understanding basic security tooling concepts to reading and designing functional extension workflows. What you'll learn: - Understand the core architecture of the Burp Extender API and how extensions interact with the suite - Register custom listeners to intercept, inspect, and modify HTTP requests and responses in real time - Analyze traffic programmatically to detect custom vulnerabilities and extract sensitive data - Implement modern API integration patterns to connect your extensions with external security tools - Structure and compile your extension code using clean, maintainable development practices This course begins with essential security testing terminology and a clear breakdown of the Extender interface lifecycle. You will then explore step-by-step written explanations of key interfaces, complete with structured code snippets that demonstrate how to handle HTTP messages, customize scanner behavior, and automate repetitive testing tasks. This course is designed for beginner security researchers, penetration testers, and software developers who want to customize their application security workflows. No prior experience with extension development is required, though a basic familiarity with web security concepts and general programming logic will help you get the most out of the material.
