catching “onChange” event in outlook 365 add-in

Question

I like to catch an onchange event in outlook 365. In particularly if the time changes. I can't find any documentation on the subject.

I have seen other add-ins like "FindTime" from microsoft do it. If you add an attendee, the add-in detects it and updates. Also an add-in like "uber ride reminder", if you change the time it checks if its in the past of future.

How do these add-ins hook up there events?

api reference

is there another way to do this?

Answer 1

I believe they are using Webhooks:

Otherwise I'm with you - there needs to be way more events in the JavaScript for Office/Mail API
