Hello, I'm hoping to migrate from a Wordpress tool called Leaky Paywall. With the tool, we have about 400 subscriptions coming through payment gateways of Stripe and Paypal. I've figured out how to import the users, and have payment gateways set up for Stripe and Paypal. I'm wondering how I might go about importing their Paypal/Stripe subscription IDs and linking that information to the imported user accounts. Does anyone have any suggestions or guidance for doing this?
