My React components have state and data that I need to send to server within PP function calls. So I placed PP code in componentDidMount method. And for some reason PP throws this error: checkout.js:4734 Uncaught SecurityError:

Is it possible to do an express checkout payment in PayPal without an account? I remember that I saw it somewhere, but I don't remember where. Once a time in PayPal there was a link under "Create a PayPal account". Robert Yes, that's certainly possible. Simply set SOLUTIONTYPE parameter to Sole in your initial SetExpressCheckout API call ( SOLUTIONTYPE=Sole ). Optionally you can also specify LANDINGPAGE=Billing for the billing page to be forced.
