The Admin API is a collection of API calls that deal with system objects in the NICE CXone system. For instance, the Admin API will allow you to change skill assignments for agents. The Admin API also includes some admin-level functions, such as recording or monitoring a call, or remotely logging off an agent.
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.
NOTE : The application calling APIs can inject an ID called the CorrelationId in the API headers. In such a case, the API response will send back the injected CorrelationId in the API response.
There is no change in the API response if the CorrelationID is not injected. See the CorrelationId: Getting Started for more information on CorrelationId.
