Payment Information

Buyer Country in Demo

Select another country to see different payment options powered by PayPal (Blik needs to set PLN currency). Buyer country is valid only in sandbox (test mode) and you should not pass it in production. The buyer country determines which funding sources are eligible for a given buyer. Defaults to the buyer's IP geolocation.

(When buyer country option is not used) PayPal auto detects the country from the buyer's IP geolocation and generates payment options with buttons.

PayPal is available in more than 200 countries/regions and support 25 currencies.

For testing, please use sample sandbox buyer credentials or test card numbers.
