Update case management case

Namespace: microsoft.graph.security.caseManagement

Important

APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.

Update the properties of a microsoft.graph.security.caseManagement.case object.

This API is available in the following national cloud deployments.

Global service	US Government L4	US Government L5 (DOD)	China operated by 21Vianet
✅	❌	❌	❌

Permissions

Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.

Permission type	Least privileged permissions	Higher privileged permissions
Delegated (work or school account)	CaseManagement.ReadWrite.All	Not available.
Delegated (personal Microsoft account)	Not supported.	Not supported.
Application	CaseManagement.ReadWrite.All	Not available.

Important

For delegated access using work or school accounts, the signed-in user must be assigned a supported Microsoft Entra role or a custom role that grants the permissions required for this operation. This API supports the following built-in roles:

Global Reader
Security Reader
Security Operator
Security Administrator

HTTP request

PATCH /security/caseManagement/cases/{caseId}

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 only the values for properties to update. Existing properties that aren't included in the request body maintain their previous values or are recalculated based on changes to other property values.

The following table specifies the properties that can be updated.

Supply a JSON representation of the resource. For polymorphic resources, include @odata.type to identify the concrete case type. The properties that can be updated depend on the case type.

To update customFields, call List customFields at /security/caseManagement/caseTypeConfigurations/{caseTypeConfigurationId}/customFields, where {caseTypeConfigurationId} matches the case type. 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.

For genericCase objects, all properties can be updated 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.

The following properties can be updated for all case types.

Property	Type	Description
displayName	String	The display name of the case.
status	String	The tenant-defined lifecycle status of the case. Use a displayName value returned in the status tree by List statuses from `/security/caseManagement/caseTypeConfigurations/genericCase/statuses` or `/security/caseManagement/caseTypeConfigurations/incidentCase/statuses`, depending on the case type.

For genericCase objects, you can also update the following properties.

Property	Type	Description
assignedTo	String	The user assigned to the generic case.
closingNotes	String	Notes recorded when the generic case is closed.
customFields	microsoft.graph.security.caseManagement.customFieldValues	Tenant-defined custom field values keyed by the exact displayName of each custom field definition.
description	String	The description of the generic case.
dueDateTime	DateTimeOffset	The target completion date and time for the generic case.
priority	String	The priority assigned to the generic case. Possible values are: `veryLow`, `low`, `medium`, `high`, and `critical`.

For incidentCase objects, the following properties are synchronized with the underlying incident. A PATCH request that includes any of these properties returns 202 Accepted with no response body. The changes might take a few minutes to synchronize and appear on the case.

Property	Type	Description
assignedTo	String	The user assigned to the incident case.
classification	microsoft.graph.security.caseManagement.incidentClassification	The classification assigned to the incident.
determination	microsoft.graph.security.caseManagement.incidentDetermination	The determination assigned to the incident.
displayName	String	The display name of the incident case.
severity	microsoft.graph.security.caseManagement.incidentSeverity	The severity assigned to the incident.
status	String	The tenant-defined lifecycle status of the incident case. Use a displayName value returned in the status tree by List statuses from `/security/caseManagement/caseTypeConfigurations/incidentCase/statuses`.

The following incident case properties aren't synchronized with the underlying incident. A PATCH request that updates only these properties returns 200 OK with the updated incidentCase object in the response body.

Property	Type	Description
customFields	microsoft.graph.security.caseManagement.customFieldValues	Tenant-defined custom field values keyed by the exact displayName of each custom field definition.
dueDateTime	DateTimeOffset	The target completion date and time for the incident case.

If a PATCH request includes properties from both groups, the method returns 202 Accepted with no response body.

Response

If successful, this method returns one of the following response codes:

For incidentCase objects, a request that includes any property synchronized with the underlying incident returns 202 Accepted with no response body. The changes might take a few minutes to synchronize and appear on the case.
For incidentCase objects, a request that updates only properties that aren't synchronized returns 200 OK and an updated microsoft.graph.security.caseManagement.incidentCase object in the response body.
For other case types, this method returns a 200 OK response code and an updated microsoft.graph.security.caseManagement.case object in the response body.

Important

Microsoft Graph SDKs use the v1.0 version of the API by default, and do not support all the types, properties, and APIs available in the beta version. For details about accessing the beta API with the SDK, see Use the Microsoft Graph SDKs with the beta API.

For details about how to add the SDK to your project and create an authProvider instance, see the SDK documentation.
