Off-site payment method from the terminal Just wondering if it is possible to setup an off-site payment from the terminal. I've already created a custom module for a custom offsite payment method for standard user checkout process. I also need to add this option to the terminal so it can be used by Admins when creating an order in the backend

Is that doable?

Just to note, I'm a Drupal beginner so I may have missed something obvious.
This isn't doable, unfortunately, because it would require a redirection process that is currently only supported by the checkout form. If it's a requirement for a site, I'd pursue a way for administrators to use the checkout form like a normal customer and submit payment being redirected from there instead.
