Billing key with foreign card
We're considering
tosspaymentstosspayments for subscription/payment services on our website. One of requirements is to provide monthly recurring payments with Korean & Foreign cards. That means user registers his card and it's used for monthly payments. According to API documentation I need to use 자동결제 API and issue billing key. However documentation also mentions that billing API doesn't support foreign cards in here https://docs.tosspayments.com/guides/billing/integration#1-고객-카드-등록하기 (해외카드, 해외결제는 지원하지 않습니다). So I was wondering if my understanding is correct? And if there's any way to 카드 등록 with 해외카드자동결제는 다른 이름으로 빌링, 또는 정기결제로 불리는 결제 방식입니다. 카드 등록창에서 고객의 카드를 한 번만 등록하고 나면, 별도의 고객 인증 없이 간편하게 결제를 요청할 수 있습니다.
