Calendar Feeds & Subscriptions

Sonderplan supports exporting and importing calendar feeds so that bookings can be synchronised with third party calendar apps that support the standard iCalendar calendar format such as Apple Calendar, Google Calendar and Microsoft Outlook.

​

Export Feeds from Sonderplan

To export bookings from Sonderplan to a third party calendar (eg Google Calendar, Outlook, Apple Calendar), you’ll need to first decide which Sonderplan feed type is best suited to your needs.

​

Types of Export Feeds

Sonderplan supports creating export iCalendar feeds at many different levels. To help avoid overloading external calendars, choose the type that gives the relevant people access to only the bookings they need to see.

​

Can feed subscribers make changes to bookings?

No, the iCalendar format (.ics) does not support bidirectional updates. It is fundamentally a one-way feed format, intended primarily for exporting calendar data from a source (server/application) to a client.

​

Feed Update Frequency

When Bookings are created, edited or deleted, Sonderplan will update all iCalendar feeds within 10 minutes.

It is up to the receiving calendar application (Apple Calendar, Google Calendar and Microsoft Outlook) to decide how often to check for updates. Generally most calendars check once every 24 hours.

If after 24 hours changes to bookings are not still not syncing to your calendar, please try and toggle the calendar to try and force a re-sync. If this fails, please contact the support department of your calendar software for troubleshooting information.

Import Feeds to Sonderplan

Sonderplan supports importing and synchronising with third party calendar services such as Google Calendar, Office 365 or any service using the standard iCalendar calendar feed format. We refer to the importing of calendar feeds as “Calendar Subscriptions”.

You can also use the import calendar subscriptions feature to automatically sync bookings from Sonderplan itself, for example to automatically copy bookings from one resource to another, or to enable collaboration on a project with another company who also uses Sonderplan.

​

Import Update Frequency

We attempt to check for updates once an hour but this may vary depending on traffic and server load. If you have concerns about the synchronisation, please check the calendar subscription logs to see when the last most recent update was.

​

Account Limits

The amount of calendar subscriptions you can create depends on your subscription package. Please contact Sonderplan support if you wish to purchase additional calendar subscriptions.

​

Create Calendar Subscription

To create a new calendar subscription, navigate to the Schedule -> button -> Calendar Subscriptions.

In the Calendar Sharing (Feeds) -> Import window, click the button and paste in your calendar feed url (.ics).

Next click the Booking Properties button and set the resources, status, project and client that will be assigned to all bookings created from the feed.

Finally, click the button to create the calendar subscription.

​

Troubleshooting Calendar Subscriptions

If you are having any issues with calendar subscription imports, please first check the logs for the subscription by clicking on the logs icon next to the relevant subscription. If too many errors are encountered, the subscription will also be automatically disabled.
