How can I create a Time Entry for an existing ticket in Zoho Desk using an API call

Hi:

I originally posted this inquiry a week ago, but have not yet received a response.

I was wondering if someone could indicate which API to use to be able to add a Time Entry for an existing ticket. I would need to add values for: Agent Name, Executed Time, Hours Spent, Minutes Spent, and Description.

Can this be done using XML response? Or does it have to be done using JSON?

Thank you very much for your help.
