Save Credit Card - Option 2

This guide describes how to securely integrate credit card tokenization into your native mobile app (iOS and Android) using Stripe's mobile SDKs. You will collect the card details, tokenize them securely with our publishable key, and send the resulting payment_method.id to our backend. We will then attach the payment method to the customer in Stripe.

Send the resulting payment_method.id to our backend

Our backend will:
