I have integrated paypal express checkout on my website. Currently with paypal account Pay as go and recurring/subscription payment both works as expected.
Now I am trying to integrate credit/debit card purchases for my website. At first , in order to do that I have enabled "PayPal Account Optional" is "ON" in my PayPal account and set following on express checkout parameters SOLUTIONTYPE=Sole and LANDINGPAGE=Billing. After doing these steps for only pay as go payment on paypal site "Check out as a guest" option showing but for recurring/subscription payment "Check out as a guest" is not showing.
Please kindly guide me on following:
What I have to do in express checkout functionality in order to enable paying through credit/debit card directly ?
Why paying through credit/debit is not showing for recurring/subscription payment ?
Whether it's possible or not to integrate credit/debit card functionality with express checkout?
Thank you in advance for your guidance.
