Getting error while accesing a coverteddocument from groupdocs

URL returned by PHP file after conversion of the document.
https://api.groupdocs.cloud/v2.0/conversion/storage/file/converted/docssample.pdf

The error I’m getting accessing that document is as followes
{“requestId”:“c4d569d0-5dcb-4f96-b9f1-e73cf9c96da9”,“error”:{“code”:“error”,“message”:“ClientId is undefined. Please check authorization.”,“description”:“Operation Failed. General Error.”,“dateTime”:“2021-02-25T06:30:24.2486833Z”,“innerError”:null}}

can someone please explain how can I access that using PHP?
Thank you
Gopal
