    @Subrat Kumar Sahu

    You can add custom attribute for user in Azure AD B2B using Microsoft Graph API extentionProperty

    While creating extension , specify targetObjects "User" to add the attribute for every user .

    Pre-requisites : Application should be registered in Azure AD and has Directory.ReadWrite.All permissions to add custom property to directory objects.

    1) Create Extension Property using POST request

    https://graph.microsoft.com/v1.0/applications/{object-id of application}/extensionProperties

    Request Body:

    {
    "name": "extensionName",
    "dataType": "string",
    "targetObjects": [
    "User"
    ]
    }

    In response you will get "name": "extension_xxxx_extensionName"

    Once attribute has been created, you can update value for each user using below:

    2) Patch request:
    https://graph.microsoft.com/v1.0/users/{user id}

    {
    "extension_xxxx_extensionName": "isPresent"
    }

    To list attribute added in user profile using:

    Get request:

    https://graph.microsoft.com/beta/users/{username}@{tenant-id}.onmicrosoft.com
