How to Fetch Tokenized Card information which can be used for other Apps and by the customer

[VishalBhatnagar]

We are currently on Magento open source and planning to move to shopify. We have built options in Magento where customers can save their card with us using tokenized and PCIDSS compliant methods and we use those tokens for future payments for functionalities like Auction Orders and Subscriptions Payments.

We are using eWay Payment Gateway.

We would like to build a custom app in Shopify which allows us to achieve the above mentioned functionality

Hi Vishal,

This could be a challenging feature to implement considering the current limitations of checkout extensions and functions - is migrating to Shopify Payments (which would allow customers to have card info saved by default) a possible option at all?
