What is the difference between the Finesse Team Notification and the Team - Get Team REST API?

The difference between the Finesse Team Notification and the Team - Get Team REST API is the following:

The Team - Get Team REST API:

• Returns a list of User objects for all of the users in that team.
• The response will contain every user's information (e.g. name, agent state, extension, etc.) at once.
• The data will be the information at that current time. So, if a change happens after the response is sent to the application, the application will not get that update.
• Polling would need to be used if the application uses the REST API to monitor the team's user information.

The Finesse Team Notification:

• The notifications follows a subscription model.
• The subscriber receives a notification whenever information of a user in the team changes. For example, if agent001 goes from Not Ready to Ready, the supervisor who is subscribed to the Team Notification will get a notification of this change.
• Will not require polling.
• The application will get the latest information instantly.
