Our application has been deployed on production and during testing our app web checkout on prod with our prod merchant account we found that we can pay with test visa card (for example, 4242 4242 4242 4242) to create real orders. We're using e-commerce endpoint https://scl.clover.com/v1/orders to create order and https://scl.clover.com/v1/orders/id/pay to pay for it, and we use https://api.clover.com/pakms/apikey to get token for hosted iframe. I also confirmed that production sdk https://checkout.clover.com/sdk.js is used on frontend. I can also see that order is being created in our merchant's account, attached screenshot with payment details as I see it in admin dashboard.
