Can OnceHub connect with shared iCloud Calendars?

How do I create an iCloud app-specific password for OnceHub?

Apple requires users to use app-specific passwords for all third-party applications such as OnceHub. An app-specific password is a single-use password for your Apple ID that lets OnceHub securely access the information you store in your iCloud calendar. To create an app-specific password, follow these steps:

1. Sign in to your Apple ID account page.
2. Click Settings.
3. Under Apple ID, click Manage. 
4. In the Security section, turn on Apple two-factor authentication if it is not on already. On older devices, use Apple two-step verification instead.
5. Under App-Specific Passwords, click Generate Password.
6. Enter a password label (for example, "OnceHub").
7. Click Create.
8. Once the app-specific password is generated, copy it.

You can now use your new app-specific password to connect OnceHub to your iCloud Calendar.

What happens if my Apple ID password changes?

If you change your primary Apple ID password, all your existing iCloud app-specific passwords are automatically revoked, and must be generated again. You will need to reconnect your OnceHub account using a new app-specific password.

Can I set Default iCloud Calendar reminders when events are created via OnceHub?

Select your profile picture or initials in the top right-hand corner → Profile settings → Calendar connection and use the Default iCloud Calendar reminders drop-down menu to select the value that you want (Figure 1).

Can I disable the iCloud Calendar invite that is sent to my Customers?

In ScheduleOnce, you can disable the iCloud Calendar invite email by hovering over the lefthand menu and selecting the Booking pages icon → Event types → your Event type→ Customer notifications and unchecking the box that sends the iCloud Calendar invite email. 

I cannot see my scheduled meeting in iCloud Calendar

In your iCloud Calendar, make sure that the calendar in which your meeting was scheduled is selected. Find it in the calendar list in the left bar and click it to select it. 

You can also select the activity in the ScheduleOnce Activity stream, then click the action menu (three dots) in the right-hand pane and select View Calendar event (Figure 2).

Why do my busy times appear in wrong time slots?

This might be due to time zone differences between the account time zone in your iCloud account and the time zone on your Booking page. To change the time zone:

• In OnceHub: Go to the Overview section of your Booking page and edit the page's time zone.
• In iCloud: Sign into your iCloud account and click Settings. Under Time Zone/Formats, click on the currently selected time zone. The Time Zone & Formats pop-up will appear. You can then select a time zone on the map, or click the time zone name below the map and select a time zone from the menu. Finally, click Done.

I’m already connected with one iCloud account. How do I switch to another?

Your account can only be connected to one calendar at a time. If you want to switch from one iCloud account to another, you will need to disconnect the previous one and then connect the new one.

Disconnect your calendar by going to your OnceHub Account, select your profile picture or initials in the top right-hand corner → Profile settings → Calendar connection. Disconnect your iCloud account and reconnect with the new iCloud account.

I cannot connect - what should I do?

This may be due to temporary communication problems with the iCloud API. Please try the following options:

1. Make sure you're using an iCloud app-specific password.
2. Make sure cookies are enabled on your browser.
3. Verify that you can login to your iCloud account.
4. Try to connect again from OnceHub.
