malikperangcic 3 Report post Posted January 8, 2015 Salam. Siapa pernah guna Paypal classic api untuk express checkout method ? nak kena create new paypal application ke? Sebab bila saya tukar dari mode sandbox ke live dengan credentials dari account paypal yang betul,asyik error "Security Header it not valid " je,padahal credentials dah tukar pada valid business account punya credentials. Perlu ke create new paypal application? Sekian terima kasih putera.com. Quote Share this post Link to post Share on other sites
