HTTP Request Tester

Server-Side Request Workbench

Let the server make HTTP requests on your behalf. Great for troubleshooting CORS, authentication, redirect chains, download interfaces, and upstream errors.

GET typically does not send a request body. Leave the right area empty to avoid accidentally sending an invalid body.

Send HTTP requests online, review results immediately.

Use Cases

  • Construct a request directly during API integration to see what the server actually returns first
  • Reproduce real requests with Header and body when troubleshooting 401/403/500 API errors
  • Customize auth info and request parameters for quick validation when debugging third-party APIs
  • Verify origin server response to confirm if CDN or proxy layer is modifying response content

Features

  • Faster lightweight API calls: GET, POST, and other common requests sent directly
  • View all response info together: Status code, response headers, response body without separate checks
  • Flexible parameters and auth: Suitable for real requests with Header, Query, body, Token, Cookie
  • Fast error troubleshooting: Convenient for origin server checks, download API validation, and third-party API debugging

How to Use

  1. 1.Enter target URL and select request method (GET, POST, PUT, etc.)
  2. 2.Set Header parameters in the request header area, fill in request body content as needed
  3. 3.Check whether to automatically follow redirects, then click send request
  4. 4.View returned status code, response header table, and response body preview content

FAQ

Can this tool replace Postman for simple API debugging?

It can do lightweight debugging, especially suitable for quickly validating request parameters, methods, response headers, and response body. Complex scenarios can still be paired with heavier debugging tools.

Is it suitable for troubleshooting 401, 403, 404, 500 API errors?

Yes. You can customize request methods, headers, and parameters to quickly reproduce problematic requests, helping locate authentication failures, permission issues, or API anomalies.

Can it include Authorization, Cookie, and custom Headers?

Yes. It's very suitable for API integration, packet capture reproduction, and gateway passthrough validation, making it easy to rebuild real request environments.

Why do online request tools help debugging efficiency so much?

Because they eliminate the need to switch local environments or write temporary code, enabling faster validation of whether APIs work, parameters are correct, and responses meet expectations.
