Unnecessary repeated "customer_id" resource requests if user breaks process flow

[POWERBACKme]

Customer_id is a property under Stripe's Payment API.

When verifying a payment method, the app sends a request to Stripe for this value. However, a user is free to navigate backward in the process, eventually bringing themselves back at some point to requesting the Customer_id, which happens each time a user breaks and returns to the process.

Instead, it might be better to store Customer_id somehow, if not with Stripe directly, then in the database or other storage.

relevant code:
components/forms/Payment/Payment.tsx
routes/api/payments.js
controller/payments/
models/User.js
