Get permission to save Kakao Pay as a payment methodServer-side![](https://b.stripecdn.com/docs-statics-srv/assets/fcc3a1c24df6fcffface6110ca4963de.svg)
If you save your customer’s payment method for future use, you need permission. Creating an agreement (sometimes called a mandate) upfront allows you to save your customer’s payment details and charge them when they’re not actively using your website or app.
Add terms to your website or app that state how you plan to save your customer’s payment method details, and let them opt in. If you plan to charge your customer when they’re offline, make sure that your terms also include the following:
- The customer’s permission for you to initiate a payment or a series of payments on their behalf for specified transactions
- The anticipated frequency (one-off or recurring) and timing of payments
- How you determine the payment amount
- Your cancellation policy, if you’re setting up the payment method for a subscription service
Make sure that you keep a record of your customer’s written agreement to these terms, and only submit charges in accordance with the agreed terms.

To reuse a Kakao Pay payment method for future payments, attach it to a Customer.
Create a Customer object when your customer creates an account with your business, and associate the ID of the Customer object with your own internal representation of that customer. Alternatively, you can create a new Customer before saving a payment method for future payments.
Create a new Customer or retrieve an existing Customer to associate with this payment. Include the following code on your server to create a new Customer:
Create a Checkout SessionServer-side![](https://b.stripecdn.com/docs-statics-srv/assets/fcc3a1c24df6fcffface6110ca4963de.svg)
Your customer must authorise you to use their NicePay account for future payments through Stripe Checkout. This allows you to accept Kakao Pay payments. Add a checkout button to your website that calls a server-side endpoint to create a Checkout Session.
