In the same workflow: API Header Inspector and Query String Parser.

REST Endpoint Tester

Send GET, POST, PUT, PATCH, or DELETE requests with custom headers and body. Inspect response status, headers, and body.

Why use REST Endpoint Tester?

Quickly exercise REST endpoints with arbitrary verbs, headers, and bodies. Useful when Postman is overkill and you need a lightweight way to reproduce a support ticket or verify a fix in staging from any laptop.

Practical tips

  • Save canonical examples as curl after you find a working combination.
  • Watch for automatic redirects that strip Authorization headers.
  • Validate JSON bodies with Request Body Validator before sending large payloads.

Common questions

Can I send file uploads?
Multipart support depends on how you encode the body. For complex uploads use a dedicated API client.
CORS blocked my call—now what?
Enable the site CORS proxy or run the same request from a server you control.
