Integration questions

Hi,

I am trying to build some test pages to integrate ZOHO subscriptions with my web site. Your API examples appear to be in Linux command line mode. I have tried to get this to work with Curl in php, but I am just getting an error.

Do you have any example of how to use PHP to access your subscription API? For example, how would one make a call to retrieve a subscription?

Also, I have a question related to the customer invoices. I can view nicely formatted invoices for a subscription via the control panel, and I would like to provide a way for my customers to view their invoices. Is there a way to display invoices via a URL or Hosted page, or do I need to retrieve the transaction data via the API and build the invoice page myself?

Thanks for your help.
