⌨️Daou (PAYJOA)
Daou payment window integration guide
1. Configure Daou PG settings
Refer to the Daou settings page to configure the PG settings.
2. Request payment
To open the payment window, call JavaScript SDK IMP.request_pay(param, callback).
In PC browsers, callback is invoked after calling IMP.request_pay(param, callback). In mobile browsers, the page is redirected to m_redirect_url.
PAYJOA payment window integration requires JS SDK 1.2.0 or later version.

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/onetimeRequest 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-idRequest 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/againFor detailed information, refer to:

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 Add delivery info and Update delivery info APIs.
