Precaution

  • When adding/updating the escrow delivery information, PAYJOA does not validate the delivery information (tracking number, courier name, etc.) received from the merchant.

To open the payment window, call IMP.request_pay(param, callback).

To request a one-time payment, use the key-in REST. The card information is not saved during this process.

To request a billing key, use the billing key request REST .

To request a billing key and initial payment, use the key-in REST .

After successfully getting the billing key and making the initial payment, the billing key is stored on the i'mport server mapped 1:1 with the specified customer_uid. For security reasons, the server cannot directly access the billing key. Subsequent payments can be requested by calling the repeat pay REST API () with the customer_uid as follows:

For escrow payment, the escrow parameter must be set to true. When the escrow payment is completed, the merchant must register the shipping information for settlement. You can manage shipping information by using the and APIs.
