## Use Cases

* Cancel timers for actions that a user takes without being prompted
* Cancel a CSAT score prompt if the user opts out
* Cancel a scheduled call if the user takes action early

## Properties

### Timer Key

This corresponds to the key set in the timer that this Action cancels. It must match the timer key in [the created timer](the-start-timer-action) exactly.

## Example

In cases where users, for example, schedule their appointment shortly after submitting their contact information, there's no need to send them a reminder message. Upon the selection of an appointment time, then, we should cancel the scheduled reminder.
