Thank you for posting your query on Microsoft Q&A, from above description I was able conclude that you are looking for a way to call the security API to get the incidents and alerts https://api.security.microsoft.com/api/incidents.
Seems like there is a documentation update in progress as new graph API has been listed in the doc. You may try using List incidents V1.0,
You need following permissions for incidents API and call
GET https://graph.microsoft.com/v1.0/security/incidents with Bearer {token} in Auth request:
- I tried same from graph and was able to run the query, got a null value as I don't have any incidents to be reported.
Please do let me know if you have any queries by responding in the comments section.
Thanks,
