Inbound iCalendar Feeds – How to Subscribe to Other Calendars

Teamup allows calendar administrators to subscribe to iCalendar feeds from other calendar products. The iCalendar format is a standardized data format for the exchange of calendaring data between calendar products. It is supported by many products, including:

  • Google Calendar
  • Apple Calendar
  • Outlook
  • Teamup Calendar managed by other groups
  • Facebook events
  • Trello calendar power-up
  • And any other applications that provide .ics feeds

iCalendar feeds are added as sub-calendars and can be shared as read-only calendars.  It is an active one-way synchronization, meaning that Teamup periodically fetches the latest feed content and updates the calendar.  Please note that it is not possible to send changes back to the feed source.

To add an iCalendar feed to your Teamup Calendar, you need to

  1. Find the feed URL of the calendar that you want to subscribe to
  2. Add the feed URL to your Teamup Calendar in Settings > Calendars.

1. Find the feed URL

Where to find the feed URL is different for each calendar product or application. See how to find feed URLs for some calendars here.

2. Add an iCalendar feed to your Teamup Calendar

Go to your administrator link. Open the Settings of your calendar and select “Calendars” on the left. Click the button “New” and choose “Add iCalendar Feed”.

Refreshing interval and status

  • The feed source is fetched periodically by Teamup to update the sub-calendar. The available refresh frequencies depend on the subscription plan of the calendar:
    • 12 hours: Basic plan, free
    • 4 hours: Plus plan
    • 1 hour: Premium plan
  • The initial fetch will take place immediately after configuring a new iCalendar feed. After that, the feed source will be re-fetched with the configured frequency.
  • The feed status (last fetch date, errors) is shown in the list of calendars.
