나는 유효한 IPN 스크립트를 가지고 있습니다. 로그인 한 사용자에 따라 데이터베이스에서 데이터를 올바르게 업데이트하고 있습니다. 따라서 결제가 완료되면 사용자 계정이 유료 회원으로 업그레이드됩니다. 그리고 이후 페이팔 구독 버튼을 사용하고 있습니다. 따라서 다음 달부터 결제 프로세스가 자동으로 진행됩니다.
그래서 여기에 (내가 잘 모르겠다) 페이팔은 내 서버에 저장된 내 IPN 스크립트와 상호 작용하지 않을 것이라고 생각합니다.paypal 가입 버튼을 사용하여 반복 지불이 발생하면 사용자 활동을 추적하십시오.
그래서, 내 질문은 : -
IPN 스크립트에 대한 내 가정이 다음 내가 어떻게 다음 결제주기 지불했다하는 사용자를 추적 할 수 맞다면? (필자는 Paypal 판매자 계정에서 사용자 지불 정보를 추적하는 것과 같은 수동 작업에 관여하고 싶지 않습니다. 스크립트로 처리하기를 원합니다. 일단 Paypal 계정에서 가입 금액을 공제하면 웹 사이트는 유료 회원으로 업그레이드 될 것입니다.)
참고로 정확히 ipn 스크립트를 통해 업데이트하고 싶었습니다. 아래는 내 IPN 스크립트입니다.
