Hello,
Thanks for your proposal.
More than the creation of a plugin to interface with Authorize CIM ; we have to perform some modifications in the HikaShop core (and in the HikaSubscription core) in order to support that special kind of plugin where the customer card can be store and HikaShop (or HikaSubscription) can bill automatically for recurring.
That structure would also be ported in other payment plugin with the same feature than CIM.
I can't tell right now if I will use Authorize to create that implementation or another plugin, like "Stripe connect" which is under development and almost ready (and it also have that feature which is not used for the moment).
Regards,
