How to Integrate iCloud With GoHighLevel Calendars

If you use ClickUp for task management and want your scheduling in one place, connecting iCloud to GoHighLevel calendars is a powerful way to sync events across devices. This step-by-step guide shows how to bridge iCloud and GoHighLevel using a CalDAV-compatible calendar client so your appointments stay accurate everywhere.

This how-to is based on the official integration method documented at HighLevel iCloud calendar integration instructions.

Understanding iCloud and GoHighLevel Calendar Sync

iCloud calendars use the CalDAV standard for syncing events. GoHighLevel calendars do not connect directly to iCloud, so you must use a calendar application that supports both iCloud (via CalDAV) and GoHighLevel to act as a bridge.

The recommended option is Thunderbird with the Lightning calendar add-on, which can manage multiple calendar accounts and keep them in sync.

Prerequisites for GoHighLevel iCloud Integration

Before you begin, make sure you have:

  • An active GoHighLevel account with at least one calendar created.
  • An Apple ID with iCloud Calendar enabled.
  • Thunderbird installed on your computer.
  • The Lightning calendar add-on active in Thunderbird (it is included by default in recent versions).

You should also have access to your iCloud security settings in case you are using app-specific passwords for CalDAV access.

Step 1: Get Your iCloud Calendar CalDAV Details

To sync iCloud with GoHighLevel through a calendar app, you first need the iCloud CalDAV connection details.

  1. Ensure that iCloud Calendar is enabled on your Apple devices and in your Apple ID settings.

  2. Locate your iCloud email address and Apple ID password (or app-specific password if you use two-factor authentication).

  3. Note that iCloud calendars are accessed via CalDAV, which Thunderbird Lightning can read.

The official HighLevel guide explains that you do not connect iCloud directly inside GoHighLevel. Instead, you let the calendar client manage the CalDAV connection and then sync that with your GoHighLevel calendar.

Step 2: Install and Prepare Thunderbird Lightning for GoHighLevel

Thunderbird Lightning is used as the intermediary calendar between iCloud and GoHighLevel.

  1. Download and install Thunderbird from Mozilla if it is not already installed.

  2. Open Thunderbird and confirm that the Lightning calendar tab is visible. In current versions, Lightning is built-in and enabled by default.

  3. If necessary, enable calendar features in Thunderbird settings so you can add network calendars.

Once Thunderbird Lightning is ready, you can add both the iCloud account and the GoHighLevel calendar links to keep them in sync.

Step 3: Add Your iCloud Calendar to Thunderbird

Using iCloud with GoHighLevel requires setting up the iCloud calendar connection inside Thunderbird first.

  1. In Thunderbird, open the Calendar view.

  2. Right-click in the calendar list area and choose New Calendar.

  3. Select On the Network because iCloud uses a remote CalDAV server.

  4. Choose the CalDAV option when prompted for the calendar type.

  5. Enter the iCloud CalDAV URL and your iCloud credentials (Apple ID and password or app-specific password).

  6. Finish the setup, then verify that your existing iCloud events appear inside Thunderbird.

When the iCloud calendar is correctly configured, Thunderbird Lightning becomes a live view of your iCloud schedule.

Step 4: Connect Your GoHighLevel Calendar

The next step is adding your GoHighLevel calendar so Thunderbird can act as a bridge between it and iCloud.

  1. Within your GoHighLevel account, open the calendar settings area.

  2. Locate the calendar you want to sync and copy its calendar URL (for example, an iCal or compatible share link as provided by GoHighLevel).

  3. Return to Thunderbird and open the Calendar view again.

  4. Create another New Calendar and pick On the Network just as you did for iCloud.

  5. Provide the GoHighLevel calendar URL when prompted, and complete the setup.

  6. Confirm that GoHighLevel events now show inside Thunderbird.

This configuration allows Thunderbird Lightning to display both your iCloud and GoHighLevel calendars together, enabling you to manage and cross-check events.

Step 5: Manage Events Between iCloud and GoHighLevel

With both calendars visible in Thunderbird, you can organize how events sync between iCloud and GoHighLevel.

  • Create new events in the calendar you want as the source calendar (for example, your GoHighLevel calendar for client appointments).

  • View overlapping schedules by enabling both iCloud and GoHighLevel calendar layers in Thunderbird.

  • Use color coding inside Thunderbird to differentiate iCloud events from GoHighLevel events.

  • Let Thunderbird handle the CalDAV communication so changes propagate back to iCloud and GoHighLevel, depending on how each calendar link is configured.

Because this process relies on standard calendar protocols, syncing may not be instantaneous; allow a short delay for updates to appear across systems.

Tips for Reliable GoHighLevel iCloud Calendar Sync

To keep your calendar integration stable, follow these best practices:

  • Keep Thunderbird updated so Lightning continues to support the latest CalDAV features used by iCloud.

  • Avoid editing the same event at the exact same time in both iCloud and GoHighLevel to reduce the risk of conflicts.

  • Periodically verify that new events added in one calendar appear correctly in Thunderbird and on the other calendar.

  • If you change your iCloud password or Apple security settings, update the credentials stored in Thunderbird for the iCloud calendar.

If anything seems out of sync, reloading calendars or temporarily disabling and re-enabling them in Thunderbird often resolves minor connection issues.

When to Use GoHighLevel Calendar Support

If you run into issues that are specific to the GoHighLevel calendar itself (for example, problems with calendar URLs, appointment types, or visibility), consult your GoHighLevel help resources or reach out to support.

Summary: iCloud and GoHighLevel Calendar Integration

Because iCloud does not connect directly to GoHighLevel, using Thunderbird Lightning as a CalDAV-compatible intermediary is the recommended way to keep your schedules aligned. By adding both your iCloud and GoHighLevel calendars into Thunderbird, you gain a unified view of all events, reduce double-bookings, and keep your appointments synchronized across Apple devices and your CRM environment.

Follow the official process outlined on the HighLevel iCloud calendar integration page and use this guide as a concise checklist whenever you need to reconnect or troubleshoot the sync.
