I added Walle app and payment gateway to our shopify store. it works for e-shop orders. But when we want to pass an order via admin UI (create an order option). we have the message : [ To add a credit card payment, activate a credit card gateway on your store ]. It's possible to use wallee for payments via shopify admin UI ?
You can create orders out of the backend but you will have to click on Email Invoice in the Shopify backend. This will create a draft order and send an email to the customer that allows him to checkout regularly through the Shopify Checkout.
I added a screenshot that illustrates this.
