Can I still use "privatelink" instead of "ticket" with api calls?

I once received instructions from Zoho regarding using a "privatelink" instead of a "ticket" which expires every 7 days. I can't get that to work now, what am I doing wrong.

The instructions from Zoho I am following are as follows:

http://reports.zoho.com/api/ <yourloginname>/<your database name>/<your table or view name> ?

ZOHO_ACTION=EXPORT

&ZOHO_OUTPUT_FORMAT=HTML

&ZOHO_ERROR_FORMAT=JSON

&ZOHO_API_KEY= <your api key>

&privatelink= <The private link value that was taken from the URL for this view>

&ZOHO_API_VERSION=1.0
