Postman Echo

API

Test API server for validating HTTP requests and responses

Overview

Postman Echo is a test API server designed to help developers validate HTTP requests and responses. It supports all standard HTTP methods (GET, POST, PUT, DELETE, PATCH, HEAD, OPTIONS) and returns structured JSON responses. Key endpoints include /get (query params), /post (form/JSON bodies), /headers (mirror headers), /basic-auth (auth flows), and /file (uploads). Use cases: Verify request parameters, headers, body content, authentication, and ensure API clients send correct requests before production integration. Ideal for testing client-side logic and debugging HTTP interactions.

Example Integration (JavaScript)

script.js JS


fetch('https://www.postman-echo.com')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
