API Request Tester
Send GET, POST, PUT and DELETE requests with headers and body, and view the status, headers and response.
Requests are sent directly from your browser, so the API must allow cross-origin requests (CORS). Don't paste production secrets on shared computers.
About the API Request Tester
A lightweight REST client in your browser for quick API checks — no app install. Choose the method, add headers and a body, and see the status code, response time, headers and pretty-printed JSON response. Because requests come from the browser, only APIs that allow CORS will respond.
