Beta Update an existing monitoring alert notification channel. A notification channel is the method of communication used to send a monitoring alert.

📘

• To maintain existing settings in a notification channel, you need to provide them when updating an object. For example, if johndoe and janedoe are currently set as usernames in an email channel, you need to include them if you're updating the usernames object with a new value. Run the Get notification channel operation and review the channel's existing settings.

• You can't update the channel_type for an existing notification channel.

• You can't update the default notification channel, or a system notification channel.
