Recurring payments

KakaoPay supports recurring transactions. To make recurring transactions, you need to:
  1. Create a shopper token.
  2. Use the token to make future payments for the shopper.

Create a token

To create a token, include in your /payments request:

  • storePaymentMethod: true
  • shopperReference: Your unique identifier for the shopper.

This triggers the recurring flow, where the shopper logs in to their Kakao account, then confirms the recurring transaction.

When the payment has been settled, you receive a webhook containing:

  • eventCode: RECURRING_CONTRACT
  • originalReference: The pspReference of the initial payment.
  • pspReference: This is the token that you need to make recurring payments for this shopper.

Make sure that your server is able to receive RECURRING_CONTRACT as part of your standard webhooks. You can enable the RECURRING_CONTRACT event code in the webhook settings page.

Make a payment with a token

To make a payment with the token, include in your /payments request:

  • paymentMethod.storedPaymentMethodId: The pspReference from the RECURRING_CONTRACT webhook.

    You can also get this value using the /listRecurringDetails endpoint.

  • shopperReference: The unique shopper identifier that you specified when creating the token.

  • shopperInteraction: ContAuth

  • recurringProcessingModel: Use Subscription for a series of transactions following a fixed time interval or UnscheduledCardOnFile for contracts with non-fixed time interval.
