API scanning and enumeration

API scanning and enumeration involve the process of systematically scanning and identifying potential vulnerabilities in the target API. Scanning is typically automated and involves the use of specialized tools to identify open ports, services, and other system details. Enumeration is the process of identifying and mapping out API endpoints, functions, and parameters that are exposed and available for use.

Techniques for API scanning and enumeration

Let us explore the different techniques that can be used in this process.

API enumeration

Sometimes, the API documentation isn’t available, and to properly scan for vulnerabilities, all endpoints should be known. We can try to map out all endpoints using manual and automated techniques.

API enumeration involves identifying and mapping out API endpoints, functions, and parameters that are exposed and available for use. This can be done using various techniques, including the following:
