I love playing around with the hosted checkout page and generating a page with different countries and currencies. You can do this both via API and directly from the Client Portal.
Here’s a couple pages that never expire or close because they’re on a loop:
The designated country and currency for these pages is Singapore and SGD (Singapore Dollar).
These do not have all of the payment methods available for Rapyd nor for Singapore. To view all the payment methods available you can use List Payment Methods By Country or go to Settings > Payment Methods in the Client Portal as described in Viewing Payment Methods
