I’ve basically got this all done with using a fairly no-frills Gravity Forms + Stripe plugin. I’m about a week away from launch and after I’m 100% certain everything is tight then I might be able to help you out @LeoB. I’m unfamiliar with WishList Member but there’s really only one spot I need to hook to make the integration. Do you know how it saves user permissions in WordPress? Are they saved as user meta?
