The Patron Services API is a collection of API calls that can be used to create patron-facing applications. A few examples may be:
To use any of the NICE CXone APIs in your application, you must have an API authentication token from the token service. See the Getting Started tutorial for information on what type of token is needed for your application and how to get an API Authentication Token.

There is no change in the API response if the CorrelationID is not injected. See the CorrelationId: Getting Started for more information on CorrelationId.
