Although there are a lot of paypal integration modules available none of them suited my needs. "Pay to Download XT" simply does what it says: Users have to pay to download certain files. Great, if you e.g. want to sell some eBooks. "Pay to Download XT" is a simple component that needs only minimum configuration. Main features are:
* Real accounts and test accounts (paypal sandbox) supported
* Simple configuration for Items to sell (Name, HTML-description, prices (price + tax and currency) and file upload)
* Large file support: FTP your files to the server and link them with your product
* CURL support for servers that don't allow fsockopen * uses Payment Data Transfer (PDT) for security (status, e.g. confirmed or pending is not checked)
* Versios for Joomla 1.0 (also runs on 1.5 in legacy mode) and for Joomla 1.5 (native and/or legacy mode available)

"Pay to Download XT" displays the description for the item & a paypal "pay now" button. By clicking, the user is redirected to paypal, makes his payment and is directed back to your site and - if the transaction was correct - may download the specified file.

"Pay to Download XT" can either be integrated into Joomla! by linking (e.g. via menu item) to the component directly or by including the product into a content item using the (optional) plugin (mambot).
