CyberSource Credit Card Processing

The CCC for Intershop Hosting enables you to use CyberSource Credit Card Services. When you issue a supported Intershop Hosting command, the component uses CyberSource to process the transaction and stores information about the transaction in Intershop Hosting's database.

Warning  Do not use any application other than Intershop Hosting to modify the database. If you use another application to modify the database, your data may be corrupted, and Intershop Hosting may not work properly

Special Considerations for Credit Card Processing

CyberSource Credit Card Processing does not support the following:

• Type II cards — Customers cannot make purchases with business-to-business cards.
• Batch billing — CyberSource Commerce Cartridge bills each transaction separately.
• Partial billing — CyberSource Commerce Cartridge bills for the total amount authorized for each transaction.
• Multiple credits —You must credit customer accounts individually.

Special Considerations for International Merchants

If you accept orders from outside the United States, consider configuring the CyberSource Commerce Cartridge to accept additional currencies or switch cards. See Enabling CyberSource Services and Tracking for more information.
