Javascript SDK
IMP.request_pay(

NICE Payments payment window

You can use i’mport REST API to request billing key, request payment, and schedule payment.

Request one-time payment

To request a one-time payment, use the key-in REST API POST /subscribe/payments/onetime. The card information is not saved during this process.

curl -H "Content-Type: application/json" \
     -X POST -d '{"merchant_uid":"order_id_8237352", "card_number":"1234-1234-1234-1234", "expiry":"2019-01", "birth":"123456", "amount":3000}' \
     https://api.iamport.kr/subscribe/payments/onetime

Request billing key

To request a billing key, use the billing key request REST API POST /subscribe/customers/{customer_uid}.

curl -H "Content-Type: application/json" \
     -X POST -d '{"card_number":"1234-1234-1234-1234", "expiry":"2025-12", "birth":"820213", "pwd_2digit":"00"}' \
     https://api.iamport.kr/subscribe/customers/your-customer-unique-id

Request billing key + initial payment

To request a billing key and initial payment, use the key-in REST API POST /subscribe/payments/onetime.

customer_uid : required for saving the billing key.

curl -H "Content-Type: application/json" \
     -X POST -d '{"customer_uid":"your-customer-unique-id", "merchant_uid":"order_id_8237352", "card_number":"1234-1234-1234-1234", "expiry":"2019-01", "birth":"123456", "amount":3000}' \
     https://api.iamport.kr/subscribe/payments/onetime

Request payment with billing key

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 (POST /subscribe/payments/again) with the customer_uid as follows:

curl -H "Content-Type: application/json" \
     -X POST -d '{"customer_uid":"your-customer-unique-id", "merchant_uid":"order_id_8237352", "amount":3000}' \
     https://api.iamport.kr/subscribe/payments/again

NICE Payments supports non-authenticated payments only through the API method.

To integrate non-authenticated payments, you need to provide a UI for accepting user’s card information. For more information, refer to the REST API page.

    "detail": [
      { "card_code": "*", "enabled": false }, // Disable all credit cards
