Please help To Find Or Create

Hi,
I am looking for the following for an outside payment provider,In my account panel with them to set up the service they are asking the following questions:

To which URL will your payment requests be forwarded to?
(Here you can type the internet address from where your service is or will be stored and to where we will send the HTTP GET request for every new payment or payment billing status update.)

And
What will be the web address to send billing reports on messages? (Here you can type the url where the billing status of messages will be delivered. The billing status will be either 'ok' or 'failed'.)

If I don't have it on my system, How can I create them?

My website is: http://www.horyea.info

Thanks
