Calendar Feed

Last updated 3/22/2026

Overview

Centerline's calendar feed lets you subscribe to your club's events directly from Apple Calendar, Google Calendar, Outlook, or any other calendar application that supports the iCal (iCalendar) standard. Instead of logging into Centerline to check the events schedule, your club's events appear right alongside your personal calendar — automatically kept up to date.

This is particularly useful for clubs that use Centerline's Events feature to schedule fly-ins, safety seminars, member meetings, ground school sessions, and other club activities. Subscribing to the feed means you will never miss an event just because you forgot to check the app.

How the Calendar Feed Works

The calendar feed is a standard .ics URL hosted by Centerline. When you add it to your calendar app, the app periodically fetches the URL and displays any new or updated events. The feed includes all club events — both upcoming events and events from the past 90 days — so you have a useful window of recent history alongside what is coming up.

The feed is read-only. You cannot create, edit, or cancel club events from your personal calendar app. All changes are made by authorized members within Centerline, and your calendar app picks them up automatically the next time it syncs.

Prerequisites

The calendar feed is only available if your organization has the Events feature enabled and if an account owner has generated a calendar feed URL in Setup > Data & Features. If you do not see the Calendar Feed section on your Notifications tab, ask your account owner to enable the feature and generate the feed URL.

Finding Your Calendar Feed URL

  1. Go to your Profile and select the Notifications tab
  2. Scroll down to the Calendar Feed card (visible only when events are enabled for your organization)
  3. The feed URL appears in the text box — it looks like https://app.flycenterline.app/api/calendar/[token]/events.ics
  4. Click the copy button (the clipboard icon) to copy the URL to your clipboard

Subscribing in Apple Calendar (Mac)

  1. Open Apple Calendar on your Mac
  2. From the menu bar, choose File > New Calendar Subscription...
  3. Paste the feed URL into the Calendar URL field and click Subscribe
  4. Give the calendar a name (e.g., "Blue Sky Flying Club Events") and choose how often to auto-refresh — Every hour or Every day is a good choice
  5. Click OK — the club's events will appear in your calendar

On iPhone and iPad, you can subscribe via Settings > Calendar > Accounts > Add Account > Other > Add Subscribed Calendar, then paste the URL.

Subscribing in Google Calendar

  1. Open Google Calendar in your browser at calendar.google.com
  2. In the left sidebar, click the + button next to Other calendars
  3. Choose From URL
  4. Paste the feed URL into the URL of calendar field
  5. Click Add calendar

Google Calendar may take a few hours to fetch the initial events. After that, it syncs approximately every 24 hours. Note that Google Calendar's refresh interval for subscribed calendars is not configurable — if you need near-real-time updates, Apple Calendar or Outlook with a short refresh interval is a better choice.

Subscribing in Microsoft Outlook

Outlook for Mac / Windows (desktop app)

  1. Open Outlook and go to the Calendar view
  2. Click Add Calendar (the exact label varies by version)
  3. Choose Subscribe from web or From Internet
  4. Paste the feed URL and click Add or Import
  5. Name the calendar and click OK

Outlook on the web (outlook.com or Microsoft 365)

  1. Open Outlook on the web and go to the Calendar view
  2. Click Add calendar in the left sidebar
  3. Choose Subscribe from web
  4. Paste the feed URL, give the calendar a name, and click Import

What Appears in the Feed

The calendar feed includes your organization's published events. Each event entry contains:

  • Title — The event name as entered in Centerline
  • Date and time — Start and end time, or a full-day marker for all-day events
  • Location — If a location was specified for the event
  • Description — The event description, if one was provided

Your personal reservations are not included in the organization events feed. The feed shows club-wide events, not individual aircraft bookings.

Tips

  • Set your calendar app's refresh interval to every hour if the option is available. Club events do not change constantly, but an hourly sync means you see additions and cancellations quickly.
  • If events stop appearing or look out of date, try removing and re-adding the subscription. Occasionally calendar apps cache a stale version of the feed.
  • The feed URL contains a security token unique to your organization. Do not share it publicly. If your account owner regenerates the token in Setup (for example, if the URL is accidentally shared), your existing subscription will stop working and you will need to copy the new URL from your Notifications tab and re-subscribe.
  • You can subscribe on multiple devices — just paste the same feed URL on each one. The club's events will appear on all of them.
  • If you do not see the Calendar Feed card on your Notifications tab, the Events feature may not be enabled for your organization. Ask your account owner to check Setup > Data & Features.
