Delphi DLL Requires Chilkat v11.0.0+

CardConnect Capture Level 3 Data

See more CardConnect Examples

Demonstrates how to send a CardConnect Capture request with Lavel 3 line item data.

If available, Level 3 line item data can be sent with the capture request, particularly for any commercial or corporate payment cards. To qualify for Level 3 Interchange rates, Level 2 data must also be provided. ...
