AuthNetAim/silent_post URL missing ...

[albrandwood]

I'm trying to configure Authorize.net ARB using AuthNetAim (v1.4)

The module says that the AuthNet silent Post URL is : AuthNetAim/silent_post ...

However, for some reason NginX (reverse proxy) is failing to get a response from fpm-php for that URL ...

What is the "correct" index.cfm?page= (or equivalent) that that URL is mapped to? (so I can get the proxy to handle it correctly)?

Thanks
