Our PayPal Express Checkout integration now has smart button support. With Smart Payment Buttons, consumers can choose which payment method they want to use. The checkout dynamically shows the most relevant payment methods at checkout, including PayPal, Credit/Debit Cards, Venmo, ELV/SEPA (Germany only) and PayPal Credit (US only). Merchants can also control the size, shape and colour.
In order to use Smart Buttons merchants will need to upgrade their extension to 1.2.0, change their "Checkout Mode" and obtain a Client ID. Further instructions can be found on the extension configuration screen.
