HTTP request

POST /security/caseManagement/cases

Request headers

Name Description
Authorization Bearer {token}. Required. Learn more about authentication and authorization.
Content-Type application/json. Required.

Request body

In the request body, supply a JSON representation of the case object. Include @odata.type to identify a supported derived type. The microsoft.graph.security.caseManagement.incidentCase derived type isn't supported for create requests.

When creating a genericCase object, you can specify all its properties except id, createdBy, createdDateTime, lastModifiedBy, and lastModifiedDateTime, which are inherited from caseManagementEntity. The API ignores these properties if you include them in the request body.

Before constructing customFields, call List customFields at /security/caseManagement/caseTypeConfigurations/genericCase/customFields. Use each definition's displayName, not its id, as the dynamic property name. The name must match exactly one definition. Each dynamic value must be an object that includes the mapped concrete @odata.type and the corresponding value, values, or valueDateTime property from the custom field value mapping; bare values aren't supported.

Property Type Description
assignedTo String The user assigned to the generic case. Optional.
closingNotes String Notes recorded when the generic case is closed. Optional.
customFields microsoft.graph.security.caseManagement.customFieldValues Tenant-defined custom field values keyed by the exact displayName of each custom field definition. Optional.
description String The description of the generic case. Optional.
displayName String The display name of the resource. Required.
dueDateTime DateTimeOffset The target completion date and time for the generic case. Optional.
priority String The priority assigned to the generic case. Possible values are: veryLow, low, medium, high, and critical. Optional.
status String The tenant-defined lifecycle status of the generic case. Use a displayName value returned in the status tree by List statuses from /security/caseManagement/caseTypeConfigurations/genericCase/statuses. Required.

Response

If successful, this method returns a 201 Created response code and a microsoft.graph.security.caseManagement.case object in the response body.
