I am trying to create a custom confirmation message for a Payment Processor, however it appears the custom confirmation message only accepts text and I cannot use any tags for the Payment Amount or Payment Type:
Seems a bit overkill for a simple message. Would be good if it just supports tags / placeholders like some of the other payment processors do (e.g. Add Calculation supports $0 for the amount)
This is a little complex as Printer Template Tags works for “submitted payments” and there is no payment at that moment.
Why do you want to display due amount there? Displaying two amounts in a single message will be harder to read. I think default confirmation message will be enough.
PS: Translation for default message will work fine on next update.
