API Testing

API (application programming interface) testing’s focus is the testing of domain logic, data responses, security, and performance. API penetration testing involves all processes of checking for vulnerabilities and building strong endpoints in your APIs. The software testing analyzes the API to check its functionality, security, performance, and reliability.

Penetration testers consider:

• What endpoints are available to be tested
• The response codes expected for successful requests
• Error messaging responses based on unsuccessful requests

One of the most common web application threats is API abuse, which can cause major business disruptions. Issues like data leakage, unauthorized access, and parameter tampering can arise with any deployed APIs if comprehensive security testing is not conducted at least annually.
