Request: implement Authorize's Silent Post function

We’re using the Authorize ARB gateway on our site and we’re missing transaction records about recurring payments. It seems our site will not get notified when the scheduled payments are completed successfully.

I wonder if there is a way in your plugin that will allow us to start receiving information about recurring payments from Authorize. We know about Authorize’s Silent Post function, but it doesn’t seem to be utilized in the current version of the gateway.

Please advise.
