Powerful API Testing Made Simple

Our automated API testing tool provides developers with a seamless way to test REST APIs directly from the browser. Whether you're building a new application or maintaining an existing one, this tool helps you verify your API endpoints quickly and efficiently.

Multiple HTTP Methods

Test any REST API with support for GET, POST, PUT, PATCH, and DELETE methods to cover all your API testing needs.

Custom Headers

Add custom headers like Authorization tokens, Content-Type, and more to properly authenticate and format your requests.

Request Body Support

Send complex request payloads with our JSON body editor, perfect for testing POST and PUT endpoints.

Why API Testing is Essential

API testing is a critical part of modern software development. With the rise of microservices and distributed systems, APIs have become the backbone of application communication. Our tool helps you:

• Verify functionality: Ensure your API endpoints return the correct responses
• Check error handling: Test how your API responds to invalid requests
• Validate performance: Get immediate feedback on your API's response time
• Improve reliability: Catch issues before they reach production

How to Use Our API Testing Tool

Getting started with our API tester is simple:

1. Select the HTTP method (GET, POST, etc.) from the dropdown
2. Enter your API endpoint URL
3. Add any required headers in JSON format
4. Include a request body if needed (for POST, PUT, PATCH requests)
5. Click "Send Request" to test your API

// Example API Request { "method": "POST", "url": "https://api.example.com/users", "headers": { "Content-Type": "application/json", "Authorization": "Bearer your_token_here" }, "body": { "name": "John Doe", "email": "john@example.com" } }

Best Practices for API Testing

To get the most out of your API testing, follow these best practices:

• Test all response codes: Verify your API returns the correct status codes (200, 400, 401, 404, 500, etc.)
• Validate response structure: Check that the response matches your expected schema
• Test edge cases: Try invalid inputs, missing parameters, and extreme values
• Secure your APIs: Always test authentication and authorization requirements
• Document your tests: Keep records of your test cases for future reference

Advanced API Testing Features

While our online tool provides basic API testing capabilities, for more advanced needs consider:

• Automated test suites: Create collections of API tests that can be run automatically
• Performance testing: Measure how your API performs under load
• Continuous integration: Integrate API tests into your CI/CD pipeline
• Mock servers: Create mock API endpoints for development and testing

Our API testing tool is perfect for quick checks and debugging during development. For comprehensive API testing solutions, explore specialized tools that offer these advanced features.
