Direct CalDAV and CardDAV URLs for Calendars and Contacts. Learn how to find and use direct CalDAV and CardDAV URLs to sync your calendars and contacts across devices. This guide helps streamline syncing for apps and services like Nextcloud, iCloud, and others.

Direct CalDAV and CardDAV URLs for Calendars and Contacts

If you’ve ever wanted to keep your calendar events and contact lists in sync across multiple devices, then you’ve likely come across CalDAV and CardDAV. These open protocols allow calendar and contact synchronization with compatible services and apps. Knowing how to find the direct URLs for these services is essential for manual configuration and better control.

What Are CalDAV and CardDAV?

• CalDAV is a protocol used to access remote calendars. It lets users view, create, and modify calendar events from different devices.
• CardDAV works similarly but is used for managing contact data, syncing address books between devices and services.

Both are built on top of WebDAV and HTTP, ensuring compatibility with a wide range of platforms.

Why You Need Direct URLs

Direct CalDAV and CardDAV URLs are especially useful when:

• Setting up accounts in apps that don’t auto-detect server settings.
• Using open-source platforms like Nextcloud, Baïkal, or Radicale.
• Connecting to services like iCloud, Google, or custom WebDAV servers.

These URLs allow you to bypass automatic setup and input the exact endpoints needed for syncing.

How to Find CalDAV and CardDAV URLs

For Nextcloud

If you’re self-hosting Nextcloud:

• CalDAV: https://yourdomain.com/remote.php/dav/calendars/username/
• CardDAV: https://yourdomain.com/remote.php/dav/addressbooks/users/username/

You can also find them in the Settings > Sync Clients section of the web interface.

For iCloud

Apple uses specific endpoints:

• CalDAV: https://caldav.icloud.com
• CardDAV: https://contacts.icloud.com

You may need to use your Apple ID and an app-specific password to authenticate.

For Google (Limited Support)

Google has deprecated full CalDAV/CardDAV support for some users but offers partial compatibility:

• CalDAV: https://apidata.googleusercontent.com/caldav/v2/your_email/events/
• CardDAV: https://www.googleapis.com/carddav/v1/principals/your_email/lists/default/

General Rule of Thumb

When in doubt, try logging into the web version of the service and check the settings or documentation. Many platforms provide direct links or allow WebDAV discovery.

How to Use These URLs

Once you have the direct URLs:

1. Open your calendar or contact app (like Thunderbird, DAVx⁵ on Android, or Apple Contacts).
2. Choose manual configuration or custom setup.
3. Enter the CalD or CardD URL along with your username and password.
4. Save and sync.

Security Tips

• Always use HTTPS to ensure your data is encrypted.
• Use app-specific passwords when available.
• Regularly update your credentials and review access logs if your service supports it.

By using direct CalDAV and CardDAV URLs, you gain more flexibility and control over how your data is synced. Whether you’re using a personal server or a commercial service, knowing these endpoints can make your setup more reliable and private.
