Tôi có một trang web hướng khách hàng của tôi đến thanh toán nhanh qua paypal. Tôi muốn cung cấp cho khách tùy chọn thanh toán mà không cần tạo tài khoản paypal. Tôi có 2 biến để gọi API SetExpressCheckout paypal nhưng không thể tìm ra nơi để đặt nó trong mã của tôi. Ai đó có thể giúp tôi với điều này?paypal solutiontype = sole
biến và giá trị:
SOLUTIONTYPE = duy nhất LANDINGPAGE = thanh toán

Xin chào Andrew, tôi đã thử làm những gì bạn đề xuất nhưng khi tôi vào trang paypal, nó vẫn yêu cầu tôi tạo một tài khoản paypal. sẽ không cho tôi trả tiền như một vị khách. – user1888584
Bạn cũng cần đảm bảo tùy chọn Tài khoản PayPal Tùy chọn được bật trong hồ sơ PayPal của bạn. Tôi nghĩ rằng nó thuộc Sở thích thanh toán trang web. –
Tài khoản Paypal tùy chọn bật và vẫn không hoạt động. – user1888584
