Auto Populating the Zoho Hosted pages with the user details from the website

Hi,

I have a website to which I want to integrate Zoho Subscriptions. I am happy embedding hosted pages. However, I want to auto populate the hosted page with the user details like First name, Last name, Email address, phone number.

I guess I should use hosted page API, can somebody assist on how to do that as I am not that comfortable with API's.

Thanks
