I'm a bit hazy about relay response
Is my understanding correct that I can either specify relay response url or receipt url?
So that if I want to use relay response, I won't get the receipt page (any receipt page)
Our framework has 2 modes:
* client redirect - upon payment payment processor returns a form with hidden fields being response values which gets auto-submitted to the internal url by the browser
* server post async - first it waits for a direct server to server post from the payment processor and then it waits for the post to the receipt page, which signifies completion
I'm trying to figure out which case would work with SIM
