About the Restful API – Advanced Knowledge Test
When a role involves system integrations, surface-level API knowledge is not enough. The RESTful API assessment evaluates advanced REST API and HTTP knowledge across authentication, versioning, rate limiting, and testing, helping recruiters identify strong backend, platform, and integration candidates.
- Request methods and responses: Candidates are assessed on the core rules behind HTTP requests and responses in REST services. This includes choosing the right method for reading, creating, or updating data, understanding which actions are safe to retry, and interpreting response codes and headers that affect caching and the format returned to clients.
- Authentication and service protection: This area evaluates how well candidates understand access control and protection in API-based systems. It covers common authentication approaches, secure handling of credentials, and the practical impact of rate limits on application reliability.
- Versioning and troubleshooting: This area focuses on the skills needed to keep integrations stable as services evolve. Candidates show their knowledge of common data formats such as JSON and XML, versioning approaches, and the tools teams use to test requests, inspect responses, and troubleshoot failures.
