I'm trying to figure out how to use Gravity Forms together with Intuit Payment Network services. It seems they have a REST API so it seems possible to write a plugin for Gravity Forms to support payment via the Intuit Payment Network. I was thinking of using the FreshBooks plugin and the authorize.net plugin as templates to see whether it's even possible (technically speaking). I was curious as to why there isn't already a plugin though, so figured I'd ask:
Is there a legal reason for the lack of a Gravity Forms / Intuit Quickbooks/Anywhere/Payment Network plugin?
