I'm working on an update on my current system with PayPal ExpressCheckout to allow users to pay without PayPal accounts. I added the
SetExpressCheckoutRequestDetails.SolutionType = SolutionTypeType.SOLE;
//Not sure If I need this one
SetExpressCheckoutRequestDetails.LandingPage = LandingPageType.BILLING;
For Merchant Account setting I activated Enhanced Recurring Payments in the Sandbox Recurring Payment and turn the PayPal account optional in the website preference.
I do not know why the Guest checkout still not showing up. Did i missed something?
Any suggestion is appreciated.
