What is signature parameter in url while testing here: https://apireference.groupdocs.cloud/viewer/#!/File_Info/HtmlGetDocumentInfoFromUrl
Every time new signature is coming in url how can I use that on rest client or on any other portal to access the APIs.
Because when I have registered for free trial I got only SID and appkey
And I am passing it url so getting auth failure error.
Please help me asap.
