Rest API test

The REST API test measures a candidate's ability to effectively create and manage RESTful services, focusing on the core principles of REST and HTTP protocols. Candidates will need to demonstrate knowledge in HTTP methods such as GET, POST, PUT, and DELETE, ensuring an understanding of CRUD operations and how these are applied to interact with different resources via endpoints. Efficiently structuring endpoints and determining when to use specific HTTP methods are crucial aspects of RESTful API design, and candidates must show competency in these areas.

Additionally, the test assesses candidates' skills in handling authentication and authorization, which are critical for secure API access and data privacy. Familiarity with token-based systems such as OAuth, as well as techniques for safeguarding sensitive information, is essential. Candidates should know how to structure requests and responses to include only necessary data, optimizing API performance by reducing payload sizes and improving response times.

Finally, candidates will be tested on error handling, testing, and integration. They should know how to handle different error types and provide informative error messages, facilitating easier debugging and better client-server communication. Testing methodologies, including unit and integration testing, as well as knowledge in integrating REST APIs with other services, will be important to demonstrate readiness for real-world API development and maintenance.
