About this tool
VS Code REST API Tester is a static, browser-based client. VS Code REST API Tester sends HTTP requests from your browser to the API endpoint you enter and shows the status, headers and body of the response.
Because the call is made by your browser, it follows the same CORS rules as any web page, so some cross-origin APIs may refuse to respond. The request is sent from your browser straight to the API you name; this site has no backend and never receives it, though that server and your network can see it. Cross-origin calls follow the browser's CORS rules, and a connection is required.
