REST API - Linked Test Cases & Incidents

Which Artifact type in this list will give you a list of all Test cases and Linked Incidents? We have been referring to these APIs to pull data from JSON format to be able to build reports via an external BI tool.  It looked like "Associations" would have the linked Test cases and incidents but there was no info retrieved while R&D was carried out via POSTMAN.
