커스텀 키보드
API로 해외 카드결제를 연동했습니다.
VISA/MASTER/JCB 등 카드를 선택하고 결제창에 진입한 후 카드번호 4번째 칸 클릭 시 커스텀 키보드가 올라오는데, 이 영역이 "입력 완료"라고 한글로 노출되고 있습니다.
이 커스텀 키보드의 입력완료를 다국어로 또는 일본어로 노출이 가능할까요?...
해외결제 renderPaymentMethods 생략 후 requestPayment 요청

그래서 아예 생략하고 사용하고 싶은 카드 (마스터, 비자, JCB)를 선택한 상태로 이후 requestPayment 요청으로 이어지는 창으로 넘기고 싶은데 가이드를 봐도 찾지 못해서 문의 남깁니다

Issues with overseas issued Visa Cards
Hello,
I want to purchase something in Aladin, a commerce that uses Toss Payments as payments platform. However after the 3D VISA security check i'm getting the error that I attached as image.
I think the implementation of Toss Payments for overseas payments is new in Aladin but every attempt ends with the same error.
This issue not only happens to me but also in Weverse, I got the same error, however somehow Weverse have also a diferent platform than Toss for overseas payments and with this platform everything was ok, so it's maybe a problem with Toss.
My card doesn't have any blocker, as I mention before it worked perfectly with another payment platform in Weverse....
