Allan,
The payment gateway who would finally deal with me is Durango Direct and the guy who makes the magic happen is:
Nathan Counley
Durango Merchant Services, LLC
(p) 866.415.2636 ext 4
(f) 413.431.2720
www.Durango-Direct.com I just recently ran into a problem with processing variable amount in Infusionsoft (single product, variable price and CVV2). I had to rewrite my form script to process directly through the Durango/NMI API. The documentation was correct, the examples provided worked out of the box: Excellent! I was able to go live with it within the hour.
As to compability between Micah's and my software, I don't think that there will be any issues here, since both of these programs work separately. I can't speak for Micah, but I am sure he, as I do, would also commit to make it work.
Best,
Bob
