When using PayPal as a payment method option to process payments for your forms, your clients should have the choice to both pay using a credit/debit card (without having PayPal account) or by signing up or logging in to their PayPal account.
To do this, simply enable PayPal Account Optional setting on your PayPal (this feature is available to Premiere and Business account holders only).
Follow these steps below to enable PayPal Account Optional on your PayPal:
1. Login to your PayPal and go to Account Settings
2. Select Website Payments on the left-hand side of the page
3. Select Update next to Website preferences
4. Make sure the PayPal Account Optional features is turned on
Scroll down to locate the section called PayPal Account Optional.
5. Save your changes.
When testing the payment on your form, make sure to use a new Private / Incognito window on your browser.
Otherwise PayPal will recognize if you ever logged in to your PayPal account and simply display the option to login to your PayPal account instead of the credit card payment form.
