What happens when an event is updated after it’s already been added to a calendar by an end-user?

There are three types of events you can share with your users using AddEvent’s tools:

1. Normal events
2. Events with RSVP enabled
3. Events via a Subscription Calendar
   
   

Normal events
Whenever you share a single, individual event with your users via an add-to-calendar button or link, this is a one-time transaction. If you update a normal event that you’ve already shared with your users, users who have already added that event to their calendar will not see those updates. However, users who add the event to their calendar after the update is made will see those updates. Normal events are typically events created in the Dashboard (without RSVP enabled), events connected to a normal “Add to Calendar” button, or events added using the Direct URL Method tool.

RSVP-enabled events
When you enable RSVP for an event, you can collect information from your users (attendees). Just like for normal events, if you update an RSVP-enabled event that you’ve already shared with your users, users who have already added that event to their calendar will not see those updates, but users who add the event to their calendar after the update is made will see those updates. However, if you need to update an RSVP-enabled event, you can let all of the attendees know of the changes by sending them an email using either our system (located on the event’s event page in the “RSVP and setting” section) or your own email vendor.  

Events via a Subscription Calendar
Subscription calendars are calendars that you create (and share) via the AddEvent Dashboard. Each calendar can contain multiple events, and your users can subscribe to these calendars to add all of the events to their personal calendars. When your users subscribe, they become 'subscribers', and a dynamic connection is created between their personal calendars and the AddEvent calendar you created. This means that when you add, delete or change an event in an AddEvent calendar you've created, that change will be reflected (after a short delay) on the personal calendars of that AddEvent calendar's subscribers. This is one advantage of sharing events via a subscription calendar.
