Getting records from s specific report

Getting records from s specific report

Hi,
  I use the following url to get records belongs to a Report.

"https://crm.zoho.com/crm/private/json/Contacts/getCVRecords?authtoken=<AUTH_TOKEN>&scope=crmapi&cvName=<REPORT_NAME>";

It returns all the Contacts not the contacts belongs to a particular Report.
It returns result even i pass some invalid report name and not returning any error saying "Invalid report name ....".

Am i missing anything here?  Should I pass any extra parameter?

Thanks,
