Hello Chris,
Thanks for reaching out to us with your question! That’s a great one.
I believe if Facebook would change the way it makes event data available, then we would likely adapt Event Aggregator to be able to handle that. So if at all, then there would be only a temporary holdup in service.
However, usually when big changes like this happen there is usually a testing / interim period – depending on the developer – so likely we would be able to do at least part if not all of the necessary adaptations before the big change goes live, thus reducing or even totally eliminating the time of switchover.
I hope this helps. Let me know if you have any further questions.
Cheers,
Andras
