Calendar feeds allow you to display reservations/events scheduled in CourtReserve directly in your personal or organizational calendar. Your calendar must support "subscriptions" or "feeds" where you can specify a URL feed (current versions of Google, Apple, and Outlook calendars all do, plus many other calendar programs).
To get the special Calendar Feed URL needed for events to show up in your (or your church's) calendar, follow these steps:
Log in with an "Admin" level account.
Navigate to "SETTINGS" >> "CALENDAR FEED"
Setup a new feed based on your parameters.
After Saving, Click the COPY URL to your clipboard.
Once you copy the URL to your clipboard, go into your calendar application and follow their instructions for adding external calendars/feeds. Here are a few links that may be helpful for doing that.
