Good Day, I have a customer in the US that has the following extension installed for credit card payments: Originally done in Apps 9 and now in Apps 10 IEE
Data Source information group Ifs.Application.Crecar_Ext.dll
There are no “Help” documentation on this. Who can assist me with a User Guide on this? I have a user guide on the Interface but not these screens:

I have to support them on this extension and also assist as the refund is not working properly but I have no idea where to find information on this.
