I am implementing a payment gateway, in which instead of authorisation/capture i.e using interfaces ccAuthInterface & ccCaptureInterface, I will be using deferred/release transaction types, to implement this I can do it using the before mentioned interfaces, but then I saw there is a interface for release i.e. paymentReleaseInterface but no interface definition for deferred, I guess there should be a interface defined for deferred type in services_paymentmethod.xml.
Also, my understanding is that authorisation/capture is same as deferred/release with the exception that authorisation/capture doesn't validate the cvv & other validations but deferred/release does. If the above statement is correct then, in order manager under "Payment Information", currently we display "Capture" button when the payment is authorised, but if we implement the above, then we need to check if the payment was using the authorisation then display capture or if using deferred then display Release button. Does this makes sense or have I missed somethings ?
