We have an client who uses two payment gateways - they have a requirement that some types of payments (contributions) use one payment gateway, and other types of contributions use another payment gateway. The resulting invoices will need a different header and contact information.
Has anyone achieved something like this before?
For a client with different payment gateways we sidestepped the issue by having different Contribution pages for each - since one was for a c4 and one for a c3 entity and used
{if $contributionPageId == X}
The invoice templates are at Administer > Communications > Message Templates in the System Workflow Messages tab.
They use smarty so can have some fairly complex logic, although I don't know whether Payment Processor is passed to the templates. You could try some smarty debugging to see what is available.
