Test and debug REST APIs with an intuitive interface, request builder, and comprehensive response analysis
API testing is a critical component of modern software development, ensuring that APIs function correctly, perform efficiently, and integrate seamlessly with other systems. Our API Tester provides a comprehensive solution for testing RESTful APIs, GraphQL endpoints, and other web services with an intuitive interface that simplifies complex testing scenarios.
The tool supports all HTTP methods including GET, POST, PUT, PATCH, DELETE, and custom methods. It features advanced request building capabilities with support for headers, query parameters, request bodies in multiple formats (JSON, XML, form-data, raw), and authentication mechanisms including OAuth 2.0, Bearer tokens, API keys, and Basic authentication.
Response analysis includes status code validation, response time measurement, header inspection, and body parsing with syntax highlighting. The tool integrates seamlessly with Performance Analyzer to correlate API performance metrics with overall application performance, and works alongside Security Scanner to validate API security implementations.
Intuitive interface for building HTTP requests with support for all methods, custom headers, query parameters, and multiple body formats including JSON, XML, and form-data.
Comprehensive authentication support including OAuth 2.0, Bearer tokens, API keys, Basic auth, and custom authentication schemes for secure API testing.
Detailed response analysis with status code validation, response time metrics, header inspection, and formatted body display with syntax highlighting for JSON and XML.
Maintains a history of all API requests with timestamps, making it easy to replay requests, compare responses, and track API behavior over time.
Support for environment variables and collections allows you to organize API tests, share configurations with teams, and switch between development, staging, and production environments.
Create automated test suites with assertions, response validation, and test chaining. Export tests for integration with CI/CD pipelines and testing frameworks.
Configure the API endpoint URL, select the HTTP method, and set up authentication. Use Code Formatter to ensure request payloads are properly formatted before sending.
Send the request and monitor response time. The tool captures all response details including status codes, headers, and body content. Use Performance Analyzer to analyze response times and identify performance bottlenecks.
Validate response structure, status codes, and data integrity. Check for security headers and validate authentication mechanisms using Security Scanner integration.
Verify that API operations correctly interact with the database. Use Database Manager to inspect database state before and after API calls.
