You can access APIs blocked by CORS restriction by using either Proxyscotch or custom middleware. You can also use the Hoppscotch web extension.


  • Enable proxy from "Settings".
  • You can replace Proxy URL with your own proxy middleware if you wish.


Since CORS is as simple as adding some HTTP headers, and it’s the only browser blocked. You can build some proxy-like component that will basically make a call for you and get the response from the desired API. You add it to the headers, and then send it back to Hoppscotch.
