Creating a custom credit card gateway
If you choose not to use Payflow Pro or SafePay, you can create a custom credit card gateway. The same connection parameters that are available for a Payflow Pro gateway are also available for a custom gateway. This includes all of the authorization modes and settings on the AR/Cash Credit Card Authorization window.
iMIS Web views
A .NET developer can write a custom gateway for the web views of iMIS. Templates and documentation are available from the iMIS Developer Resources.
iMIS Desktop
An Xtender developer can use Visual Basic to write a custom gateway for iMIS Desktop. Templates and documentation are available from the iMIS Support community under Extension Products. Instructions for customizing the gateway are in the documentation and the control files. The Xtender developer must define and carefully document which of the fields should be populated, if any, and for what purpose.
