API testing is a type of software testing that focuses on verifying the functionality, reliability, performance, and security of Application Programming Interfaces (APIs). It involves sending requests to the API and analyzing the responses to ensure they align with expected behavior. API testing is crucial for ensuring the quality of applications, especially in modern systems where APIs play a vital role in communication between different components

Key characteristics :

• Functionality : Verifies that APIs perform their intended functions correctly, such as creating, reading, updating, and deleting data
• Reliability : Ensures APIs are stable and consistent in their behavior, even under varying conditions
• Performance : Assesses how quickly APIs respond to requests and handle different loads
• Security : Checks for vulnerabilities and potential security breaches, ensuring that APIs are protected against unauthorized access and attacks
