I have already known 3 different web domains for the API’s production mode:

  1. hub.alphapaymentscloud.com
  • hubuat.alphacommercehub.com.au
  • hub.sg.alphapaymentscloud.com

Which formal rules should my Magento 2 extension use to choose the API’s production domain among these 3 when a merchant has switched my extension from the test/sandbox mode to the production mode?

[AlphaCommerceHub] Why does the «API Integration Guide(Nov 2017)» recommends to send the API requests to an unknown hub.apcld.net domain?
