Clickfunnels Build Integration to Manage Payments

I am the owner of a small business that sells subscriptions to online video lessons on the Clickfunnels platform (using their Membership Funnel). The only thing I haven't been able to figure out is building the ability for customers to manage their own accounts (cancel membership, update credit card information, etc.) I am looking for someone experienced in Clickfunnels development who is able to build an API that would directly update member information within Stripe (the payment gateway) or Clickfunnel's recommended Stunning platform ([login to view URL]) I'm more than happy to provide a full requirements description or any UX/design work and will be available for all testing/QA.
