Unable to retrieve custom attribute via graph API

Question

Hello,

I am trying to retrieve the custom attributes for a user via graph, but cant seem to find them in the result set. Please can you advise what am i missing and how to get those values. Do i need a different query or "join" to another parameter to get the value. I am a global admin and have the attribute assignment admin.

Answer 1

You can try the following query to show the custom attributes for the user

https://graph.microsoft.com/v1.0/users/manu@exchangeonline.in?$select=onPremisesExtensionAttributes

$select=displayName,onPremisesExtensionAttributes will show only the display name along with all the custom attributes

Answer 2

You have to specifically request the custom attributes themselves, or the set as a whole. For example, this query will include all custom security attributes:

https://graph.microsoft.com/beta/users?$select=id,displayName,customSecurityAttributes

Do make sure that the CustomSecAttributeDefinition.Read.All scope has been consented to, and if you are running this via the Graph explorer tool (or any other method that leverages delegate permissions), that the corresponding user has sufficient permissions to access the CSA set(s) in question.

Additional details and more examples can be found in the official documentation: https://learn.microsoft.com/en-us/azure/active-directory/enterprise-users/users-custom-security-attributes?tabs=ms-powershell

I have also tried the following and it is working form me.

You can try the following query to show the custom attributes for the user

https://graph.microsoft.com/v1.0/users/email@yourTenant.com?$select=onPremisesExtensionAttributes

this will return the following json response

{
    "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users(onPremisesExtensionAttributes)/$entity",
    "onPremisesExtensionAttributes": {
        "extensionAttribute1": "somevalue",
        "extensionAttribute2": null,
   		"extensionAttribute15": "November 12, 2023"
    }
}
