CreateRequest takes several parameters which are used to create a "Request" ticket within the configured Zendesk application. Documentation for this Zendesk entity can be found here: https://developer.zendesk.com/rest_api/docs/support/requests#create-request
A subject parameter and a body parameter are required and then a number of optional parameters can be given. Debug is for testing purposes and does not change any of the underlying functionality, this simply returns the full response JSON from Zendesk, including headers, instead of the actual response payload itself.
The parameters fieldMapName and custom_fields are discussed in: Install and Configuration
