I've been creating orders on Shopify using the Shopify REST API.
I'd like to specify the gateway variable to Amazon Pay. Which code should I use for that?
On the API page they have the example "shopify_payments" for the gateway and a link to other payment gateways but these only appear as a name like for example "Shopify Payments".
Amazon shows up as "Amazon Pay", does that mean that I have to populate the gateway variable with "amazon_pay"?
Thanks for the help!
