Namespace: microsoft.graph

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.

Retrieve the properties and relationships of a servicePrincipal object.

This API is available in the following national cloud deployments.

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) Application.Read.All Application.ReadWrite.All, Directory.Read.All, Directory.ReadWrite.All
Delegated (personal Microsoft account) Not supported. Not supported.
Application Application.Read.All Application.ReadWrite.OwnedBy, Application.ReadWrite.All, Directory.Read.All, Directory.ReadWrite.All

Note

  • A service principal can retrieve its own application and service principal details without being granted any application permissions.
  • The Application.ReadWrite.OwnedBy permission allows an app to call GET /applications and GET /servicePrincipals to list all applications and service principals in the tenant. This scope of access has been allowed for the permission.
  • To read the customSecurityAttributes property:
    • In delegated scenarios, the admin must be assigned the Attribute Assignment Administrator role and the app granted the CustomSecAttributeAssignment.Read.All delegated permission.
    • In app-only scenarios using Microsoft Graph permissions, the app must be granted the CustomSecAttributeAssignment.Reade.All application permission.

HTTP request

You can address the service principal using either its id or appId. id and appId are referred to as the Object ID and Application (Client) ID, respectively, in app registrations in the Microsoft Entra admin center.

GET /servicePrincipals/{id}
GET /servicePrincipals(appId='{appId}')

Optional query parameters

This method supports the $select and $expand OData query parameters to help customize the response.

This method supports the $count, $expand, $filter, $orderby, $search, $select, and $top OData query parameters to help customize the response. Some queries are supported only when you use the ConsistencyLevel header set to eventual and $count. For more information, see Advanced query capabilities on directory objects.

By default, this API doesn't return the public key value of the key in the keyCredentials property unless keyCredentials is specified in a $select query. For example, $select=id,appId,keyCredentials.

The use of $select to get keyCredentials for service principals has a throttling limit of 150 requests per minute for every tenant.

Request headers

Name Description
Authorization Bearer {token}. Required. Learn more about authentication and authorization.
Accept-Language Language code. Optional.

Providing the Accept-Language header with a supported language code, such as es-ES or de-DE, will return localized values where available. Note that the header is not supported for list operations.

Request body

Don't supply a request body for this method.

Response

If successful, this method returns a 200 OK response code and a servicePrincipal object in the response body.

HTTP/1.1 200 OK
Content-type: application/json

{
    "@odata.context": "https://graph.microsoft.com/beta/$metadata#servicePrincipals(id,appId,displayName,appRoles,publishedPermissionScopes)/$entity",

            "value": "profile"
        }
    ]
}

Example 3: Get the custom security attribute assignments of the specified service principal

The following example gets the custom security attributes of the specified service principal.

Attribute #1

  • Attribute set: Engineering
  • Attribute: Project
  • Attribute data type: Collection of Strings
  • Attribute value: ["Baker","Cascade"]

Attribute #2

  • Attribute set: Engineering
  • Attribute: CostCenter
  • Attribute data type: Collection of Integers
  • Attribute value: [1001]

Attribute #3

  • Attribute set: Engineering
  • Attribute: Certification
  • Attribute data type: Boolean
  • Attribute value: true

Attribute #4

  • Attribute set: Marketing
  • Attribute: Level
  • Attribute data type: String
  • Attribute value: "Public"

To get custom security attribute assignments, the calling principal must be assigned the Attribute Assignment Reader or Attribute Assignment Administrator role and must be granted the CustomSecAttributeAssignment.Read.All or CustomSecAttributeAssignment.ReadWrite.All permission.

Request

GET https://graph.microsoft.com/beta/servicePrincipals/{id}?$select=customSecurityAttributes

Response

HTTP/1.1 200 OK
Content-type: application/json

{
    "@odata.context": "https://graph.microsoft.com/beta/$metadata#servicePrincipals(customSecurityAttributes)/$entity",
    "customSecurityAttributes": {
        "Engineering": {
            "@odata.type": "#microsoft.graph.customSecurityAttributeValue",
            "Project@odata.type": "#Collection(String)",
            "Project": [
                "Baker",
                "Cascade"
            ],
            "CostCenter@odata.type": "#Collection(Int32)",
            "CostCenter": [
                1001
            ],
            "Certification": true
        },
        "Marketing": {
            "@odata.type": "#microsoft.graph.customSecurityAttributeValue",
            "Level": "Public"
        }
    }
}

If there are no custom security attributes assigned to the service principal or if the calling principal does not have access, the response will look like:

HTTP/1.1 200 OK
Content-type: application/json

{
    "@odata.context": "https://graph.microsoft.com/beta/$metadata#servicePrincipals(customSecurityAttributes)/$entity",
    "customSecurityAttributes": null
}
