According to paypal, it is possible to pay with a credit card and without a paypal account (How to Make PayPal Account Optional for Buyers: https://www.youtube.com/watch?v=fBeeGgIFbU0, and another link: https://hotcakescommerce.zendesk.com/hc/en-us/articles/360016093071-PayPal-Express-Checkout-Without-Logging-In)
That is what we need .
We have configured the standard payment provider "PayPal Express".
And marked the checkbox: Enable guest checkout - allows users with no PayPal account to check out & optionally create a PayPal account (https://doc.dynamicweb.com/documentation-9/ecommerce/payment/paypal-express-checkout)
With this configuration, it appears the pay by credit card button, but still is compulsory create an account in paypal...i dont know what else i have to configured or if there is something else i should know...
Thank you!
