An issue object is any query, request for change, problem, bug, suggestion or off-specification raised during the project. It can be about anything to do with the project. It includes the Issue ID that is used to make reference to the particular case throughout the system. Each Issue ID is unique and automatically generated by the Communifire system.
Please Note Refer this wiki on how to create a new case via REST API.
