How to configure Instabill so that user will pay for downloading certain files? (And how to configure a shopping cart for such purposes?)

Thank you in advance.

when you setup the items in your catalog, there is a redirection page where you will be sent if your payment goes through. You can have the user redirected to the paid-for documents index page where you have to check the referrer header to make sure the user hasn't come directly to the page (ie. without paying).

Thank you, my idea was the same :), but how can you check that referral links wasn't falsified?
And what about shopping cart, how you can check what products have been bought?

If you need to identify which item has been ordered (if items have different pricing) you need to setup each item seperatly in your catalog in instabill. There are two ways for you to know which item has been ordered.

1) Setup a unique redirection url for each item.
2) Setup some sort of identifier as partof the URL to the redirection URL. For example: http://www.mydomain.com/thankyou.php?item=12
And use a unique item= for each item.

If you are really worried about people falsifying referrer..
with instabill this will get somewhat hairy. I guess the only way you can be sure is to write some code which would log into your instabill account, pull the latest transactions and search for the order with the IP of the user coming in. This would slow things down significantly, and if you get many orders I am not sure if instabil would like this idea :)

Cool idea! :)
I understand that it could be quite slow, but may be Instabill could install some B2B software, which will use some simple protocols for communication.

You can enter an optional paragraph for the email that is sent to your customer after the authorized transaction, under Settings & Options >> Email Reciept.

You could enter a password there that would be required to access the site with the download material. This way only those who recieve the email confirmation can get to the information. :)
