Hey Bill,
Ok. Provide us with eWay Sandbox merchant account, so we will add it back to PP 4.0.
It worked fine in the old Payplans so should not be hard to upgrade.
As in PayPlans 4.0 , We have completely revamped the entire workflow , so eway payment method need to change to make it compatible to PP4.
Also do you have documentation for users who wish to develop their own gateway? I want to develop for various cryptocurrencies.
I am sorry , but currently we don't have any developer document to create payment method. Either you can take reference from existing payment methods.
Thank you for understanding !
