Remote Event Receiver in Hostweb

Question

I have a Farm Solution that management is pushing to be ported to the App Model. This Farm solution has a Custom Action which, when configured, dynamically attaches a ListItem Event Receiver to the List chosen by the user.

Is it possible to attach a Remote Event Receiver to a list programmatically ? Can you add a Remote Event Receiver to the Host Web or does it have to exist in the App Web attached to a list in the App Web?

Answer 1

For your question "Is it possible to attach a Remote Event Receiver to a list programmatically?, The answer is YES. Yes it is possible to attach the remote event receiver programmatically.
