After you have generated a payment link and the shopper clicks on the link, the available payment methods will be displayed to them. The payment methods shown are the payment methods that are enabled on your merchant account and that are available based on the payment link’s:

• countryCode
• currencyCode
• amount

Based on the shopper’s country, you can customize the order of the payment methods, as well as block specific payment methods through the Customer Area settings as explained here. 

If you are creating payment links through the API, it is also possible to allow or to block specific payment methods per created link, as explained here.
