What is Iamport?

Iamport (아임포트) is a South Korean payment gateway aggregator that simplifies integration with multiple Korean payment methods through a single API. It provides unified access to major Korean PGs (Payment Gateways) including KG Inicis, NHN KCP, LG U+, Payco, Kakao Pay, and Naver Pay.

For developers building e-commerce for the Korean market, Iamport eliminates the complexity of integrating with each payment provider individually. Its standardized API handles the quirks and requirements of various Korean payment systems, including the unique certificate-based authentication common in Korean online payments.

Iamport supports credit cards, bank transfers, virtual accounts, mobile payments (Kakao Pay, Naver Pay), and convenience store payments. It's essential for any international company looking to accept payments from Korean consumers through their preferred local payment methods.
