How to Use API Tester

Getting Started

  1. Select HTTP method (GET, POST, PUT, PATCH, DELETE, etc.)
  2. Enter the API endpoint URL
  3. Add query parameters and headers as needed
  4. For POST/PUT/PATCH, add request body
  5. Click "Send" to make the request

HTTP Methods

  • GET - Retrieve data from the server
  • POST - Create new resource on the server
  • PUT - Replace entire resource on the server
  • PATCH - Partially update a resource
  • DELETE - Remove a resource from the server
  • HEAD - Like GET but without response body
  • OPTIONS - Get communication options for the resource

Features

  • Support for all HTTP methods
  • Add custom headers and query parameters
  • Format and view JSON responses automatically
  • Display response status, headers, and body
  • See response time and size
  • Copy and download responses
  • All requests are made client-side (CORS enabled endpoints only)

Example Request

URL: https://jsonplaceholder.typicode.com/posts/1
Method: GET
Headers: Content-Type: application/json

Tips

  • Use JSONPlaceholder for testing: https://jsonplaceholder.typicode.com/
  • CORS restrictions may apply depending on the API server
  • Common headers: Content-Type, Authorization, Accept
  • JSON body must be valid JSON format
