General
The following describes the function of an external download. "External" means that the download is not provided by WEBSALE AG, but by an external system, which is linked to after purchase.
Identification of external download products
Products that are downloaded from an external system after purchase must be marked accordingly in the shop using the "ExternalDownload" flag. The value must be set to "y". A designer can handle each external download product accordingly in the templates and in the shopping cart and display the corresponding download link.
The external download link is also passed in the order data.
Linking to the external download system
As soon as an external download product is purchased, a download link is generated for each download item in the shopping cart.
This is displayed on the following pages:
Order confirmation page
Confirmation e-mail
Order history
Â
A download link contains the following data:
Parameter | ID | Description | Required field |
|---|---|---|---|
Timestamp | 1 | UNIX timestamp at the time of generation. Number of seconds since 01.01.1970 | yes |
ShopID | 2 | The ShopID | yes |
SubshopID | 3 | The SubshopID | yes |
OrderID | 4 | The shop order number | yes |
5 | The eMail address of the customer | yes | |
CustomerNumber | 6 | The customer number, if available | no |
UserIndex | 7 | The UserIndex of the shop, if available | no |
ProductNumber | 8 | The product number | yes |
Format:
https://<domain-external-system>/?dldata=<1>Timestamp</1><2>Shopid</2>...<8>ProductNumber</8>
Example:
https://<Domain-Externes-System>/?dldata=<1>1462879316</1><2>myshop</2>...<8>1234567890</8>
The data is not encrypted in plain text, but
AES-256-bit-encrypted
hex-encoded
In the 1st step, the data string "<1>1462879316</1><2>myshop</2>...<8>1234567890</8>" is AES 256-bit encrypted.
In the 2nd step the binary data is hex encoded.
The final link then has the following format:
https://<domain-external-system>/?dldata=aa125609cdeffa34321aab....
The encryption password is fixed on both sides and is provided by WEBSALE.
Secure payment methods
As soon as at least one external download product is in the shopping cart, only "secure" payment methods can be offered. Which payment method is considered secure (credit card, PayPal, Sofortüberweisung etc.) can be freely configured in the shop.
