Hello, I've got a problem with the checkout. Integration between Wallee and Shopify works and as a payment processor we use Braintree. The thing is every time you "complete order" you get the message you can see in the screenshot. Everything in the Configuration tab looks ok, so we are lost. We like your service and would appreciate help, thank you! !
Hi Thank you for your email.
Can you please tell us which payment method you're trying to use? Are you sure this method is enabled for your configured Braintree account?
