It's actually not clear this is a requirement, but I noticed when logged into our Canadian sandbox that the API keys page specifies an API endpoint ending in .ca. We have to use the Canadian URL for loading the JavaScript library to submit Canadian transactions, but all of my tests for follow-up operations (voiding, capturing, and refunding) worked even though we always submit API requests to the .com endpoint.
In case there's some nuance here we might miss, let's evaluate using the configuration of a payment's payment gateway plugin to submit the API request to the appropriate domain. Because of the state of Affirm's documentation, I can't predict if this will work or not. If it doesn't, just close this ticket out.
