Public Cancel URL

This is for creating a client-facing endpoint that would run the cancel meeting flow when executed. 

The public cancel URL with the following structure:

https://subdomain.chilipiper.com/book/cancel/{Event.Id}

Where the {Event.Id} at the end would accept:

1. CP Event ID
2. SFDC Event ID

You can configure your Meeting Templates and reminders to contain:

{!CP.Meeting.CancelURL}

Both internal team members and external users with this URL will be able to cancel the meeting.

Behavior

When the cancel URL is clicked for a meeting, the expected behavior is the following:

1. The prospect/customer will see a screen asking them to confirm the cancelation or reschedule with the date and time of the originally booked meeting. 
   
2. Upon confirming the cancelation, the following will happen:
   1. The User who clicks on the confirm button will see a confirmation message. 
   2. The Meeting and any associated meeting buffers will be deleted from the Calendar.
   3. The Assignee will receive an email notification that the meeting has been canceled, and the URL will reflect this:
      
   4. If using webhooks during the original booking, a webhook will be sent with actionType = ‘prospect_cancel’ and CP Event ID to let your system know the meeting was canceled. 
   5. If you are embedding the URL within a page, Chili Piper adds a new message to the browser `prospect_cancel` that will send once the cancelation is confirmed, allowing you to perform actions such as redirecting away from the page.
   6. If the prospect attempts to reschedule the event, they will be presented with a message indicating it has instead been canceled:
