Hi,
HikaShop and Emerald integrate fine with the integration enabling Emerald subscriptions to be HikaShop products. So, customers are then able to e.g. add Emerald subscriptions to the HikaShop cart, multiple at once, together with other HikaShop products, you can use the HikaShop currency and all other systems, etc. Subscription pricing and all other sales-related things for subscriptions are then set and managed in HikaShop, while Emerald still manages subscription-related things such as e.g. user groups, duration, subscription status emails, etc.
However, recurring payments for Emerald subscriptions sold through HikaShop are then not possible, as per Sergey's (mintjoomla.com) statement in his support forum:
Recurring process will not work with Hikashop. Since you pay through Hikashop payment gateway it will not setup paypal subscription. It is technically not there. So you can only purchase plan with Hikashop product but you cannot setup recurring subscription.
You see Emerald in this integration is side extension. You make your purchase through Hikashop. And Hikashop get data and send to paypal to initialize payment. Emerald has nothing to do with that. We only create subscription to user when successful order occur.
