Crystal Report hosted on BI Platform : Generating PDF response using .NET Application

Hi Team,

We have Crystal Reports 2013 Reports hosted on a BI Platform. And, we are trying to download pdf format of the Reports for a custom application, using Restful Webservices.

I am able to authenticate using ADSSO, download a valid X-SAP-Security-Token, and explore the details of folders and reports hosted on our BI Platform using /infostore URLs.

Now, as per the community responses, I need to create an Instance of Report, and pass this InstanceID to below URL

~/biprws/infostore/<instanceid>/rpt/export?mime_type=application/PDF

But, on trying to create instance ID by passing Report ID, I get an error :

The remote server returned an error: (404) Not Found

I am stuck here, can someone help?
