    How to Use the API Testing Suite

    Set Up Your Request
    
                        
    Select the HTTP method (GET, POST, PUT, DELETE) and enter your API endpoint URL. This is the foundation of your API test.
    
                        
    
                            
    GET https://api.example.com/users

    Add Parameters and Headers
    
                        
    Use the Params tab to add query parameters, Headers tab for custom headers, and Auth tab for authentication (Bearer tokens, Basic Auth, etc.).
    
                        
      
                            
    • Query parameters: Add key/value pairs for GET requests
      • 
                            
    • Headers: Set Content-Type, Authorization, etc.
      • 
                            
    • Authentication: Bearer tokens, Basic Auth, or custom headers
      •

    Configure Request Body
    
                        
    For POST/PUT requests, use the Body tab to add request data. Choose from JSON, Form data, XML, or custom formats.
    
                        
    
                            
    {
  "name": "John Doe",
  "email": "john@example.com"
}

    Send and Analyze Response
    
                        
    Click "Send Request" to execute your API call. Review the response body, headers, and timing information in the output section.

    REST API Testing
    
                    
    Test RESTful API endpoints with different HTTP methods, headers, and request bodies to ensure proper functionality.
    
                    
    
                        Example Request:
                        
    POST /api/users
Content-Type: application/json
Authorization: Bearer your-token-here

{
  "name": "Jane Smith",
  "email": "jane@example.com"
}
    
                    
    
                
    
                
    
                    
    Authentication Testing
    
                    
    Verify authentication mechanisms by testing endpoints with different auth methods and validating token expiration.

    How do I test API endpoints?
    
                    
    Simply enter your API URL, select the HTTP method (GET, POST, PUT, DELETE), add any required headers or body data, and click Send Request. Our tool will handle the rest and display the response.
    
                
    
                
    
                    
    What authentication methods are supported?
    
                    
    We support Bearer Token authentication, Basic Auth (username/password), and custom headers. All authentication data is processed locally in your browser for security.
    
                
    
                
    
                    
    Can I test APIs with different content types?
    
                    
    Yes! Our tool supports JSON, XML, Form URL-encoded data, and custom body types. The Content-Type header is automatically set based on your selection.
    
                
    
                
    
                    
    Is my API data secure?
    
                    
    Absolutely. All API testing happens client-side in your browser. Your requests, responses, and authentication credentials never leave your device or get stored on our servers.
