How does it work?

  • 8 Validations for COMPLETE SECURITY of your Digital Files before downloaded:

    These Validations are:

    1. Checks for incompatible Browsers (the older versions) ie.; browsers which do not work with our file download script.
    2. Checks that the transaction information returned by Paypal is indeed valid. (See PayPal's Instant Payment Notification Manual on how PayPal validates its transactions.)
    3. Checks that the item number has not been changed from the web form.
    4. Checks that the cost has not been changed from the web form.
    5. Checks that the currency has not been changed from the web form.
    6. Checks for Duplicate Transactions.
    7. Checks that the transaction is complete.
    8. Checks the PayPal Business Account ID.


  • The application is written in Perl, uses a MySQL database and incorporates PayPal's Auto Return and Payment Data Transfer (PDT) * features.


Evaluate A+ Download as follows:
  1. Tour the administrative web panel . Check out the cart manager then run the transaction reports.
  2. Purchase multiple test files for a penny and see how easy it is to download mulitple files.
  3. Download.


* Note that A+ Download does not work on GoDaddy Servers. Apparently GoDaddy Servers use a proxy server for outside connections required by the Paypal Payment Data Transfer (PDT) process.
