FAQPage Schema
How do I automate REST API testing for correctness and security compliance?

You can validate REST APIs before deployment by integrating automated probing into CI pipelines, running endpoint discovery to map surfaces, and executing auth, error handling, and performance timing checks to generate a scored report.

Can I integrate API endpoint discovery and automated probing into a CI pipeline?

Yes, you can integrate automated endpoint discovery and probing into CI pipelines to validate new or updated backend services and microservices before release, generating detailed compatibility and security reports.

What does automated REST API performance analysis and standards conformance reporting include?

Automated REST API performance analysis includes response-time measurements, robustness checks for input validation, and standards conformance reporting to verify API resilience and correctness across backend services.

Does automated API testing work for microservices and backend services?

Automated API testing works for microservices and backend services by applying endpoint discovery, security checks, and performance timing to map API surfaces and validate correctness before deployment.

How do I check REST API authentication handling and input validation automatically?

Automated API testing checks authentication handling and input validation by probing discovered REST endpoints for security vulnerabilities and robustness, producing a scored report with actionable fixes for any identified issues.
