Cancel URL information

카카오페이 API

Good day, @anon35427268
Please assist with the cancel payment option (When user closes payment window by clicking on ‘X’) ?
I cant seem to find what information will be passed to the callback url - i.e cancel_url ?
What will be passed to the cancel URL by KAKAO pay? e.g TID, partner_order_id? I cant seem to find that information in
your documents. Apologies, I do not speak Korean Language.

Google Translate :
좋은 날,
결제 취소 옵션 (사용자가 'X’를 클릭하여 결제 창을 닫을 때)을 도와주십시오.
콜백 URL에 어떤 정보가 전달되는지 찾을 수 없습니다-즉 cancel_url?
KAKAO pay에 의해 취소 URL로 전달되는 것은 무엇입니까? 예 : TID, partner_order_id? 정보를 찾을 수없는 것 같습니다
당신의 문서. 사과, 나는 한국어를 못해요.

Can anyone from Kakao pay assist? Another query is what happens if communication between our server
and Kakao pay server is interrupted? example, a customer makes a payment successfully but when being redirected
to us from Kakao the connection is interrupted and therefore approval call is not made. How will we handle this?
Will this payment be stuck in a pending state?
