Specifically, I'm not sure if I can create a single subscription for message events from ALL extensions (WITHOUT using a super admin account). The message store api only allows for message extraction for individual extensions one at a time (without a super admin account). So I can only assume the message events work the same way. And if that is the case, that means that I have to create a separate subscription for each and every extension, correct?
Or, alternatively, can I subscribe to message events using a filter like this:
without a super admin account?
My concern is this: If I have to create a separate subscription for each and every extension, what happens when the company adds new extensions? I don't see an event I can subscribe to for when new extensions are added. Which means I'm back to polling for new extensions. Hopefully I can avoid that. That's the point of the sub model.
And it would be just a whole lot easier if I can just create a single subscription for messages for the whole company.
