A direct contract with NaverPay (결제형), so buyers can pay with NaverPay.
In the NaverPay center (admin.pay.naver.com), apply as a 결제형 merchant: the kind that adds NaverPay as a way to pay in your own app. Have your business registration certificate ready, along with any other documents NaverPay lists for your business type.
When NaverPay gives its first approval (1차 승인), it emails your 파트너ID (페이센터아이디), ClientID, Client Secret and ChainID.
In the PortOne console, open 결제 연동 → 연동 관리 → 채널 관리. Switch the mode to 실연동, pick 네이버페이 and its payment module, and click 다음. Name the channel, enter the four values from the email, choose 과세구분, and save.
The channel shows in the list with its channel key, starting with channel-key-. Copy it.
In your project, open Payments → Connect → More payment methods. Paste the channel key into NaverPay channel and click Connect.
That is expected until NaverPay’s final review starts. Once NaverPay shows at your app’s checkout, ask the NaverPay center for its final approval (최종 승인).
NaverPay’s smallest payment is 100 won.
NaverPay takes Korean won only.
