How to get user group information from Azure AD B2C - azure-active-directory

Question

I am using Microsoft Graph for fetching user information, namely "List users" API.
Following is the code for accessing the user information :
ClientCredential clientCred = new ClientCredential(clientId, clientSecret);
AuthenticationResult authenticationResult = await authenticationContext.AcquireTokenAsync(resourceId, clientCred);
string token = authenticationResult.AccessToken;
Debug.WriteLine("token=" + token);
var responseString = String.Empty;
string[] scopes = { "User.Read" };
using (var client = new HttpClient())
{
string requestUrl = "https://graph.microsoft.com/v1.0/users?$select=id,givenName,surname";
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, requestUrl);
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", token);
Debug.WriteLine(request.ToString());
HttpResponseMessage response = client.SendAsync(request).Result;
responseString = response.Content.ReadAsStringAsync().Result;
Debug.WriteLine(responseString);
}
Output :
{
"#odata.context": "https://graph.microsoft.com/v1.0/$metadata#users(id,givenName,surname)",
"value": [
{
"id": "000000000-0000-0000-000-000000000",
"givenName": "XXX",
"surname": "XXX"
}, {
"id": "000000000-0000-0000-000-000000000",
"givenName": "XXX",
"surname": "XXX"
}
]
}
How to the get user group ?

Answer 1

You can call the user: getMemberGroups API action for a user to get their groups:
You need to make a request like so:
POST https://graph.microsoft.com/v1.0/users/user-id-here/getMemberGroups
Content-type: application/json
Content-length: 33
{
"securityEnabledOnly": true
}
The securityEnabledOnly parameter defines if it should only return security groups. Setting it to false will also return the user's Office 365 group memberships for example.
An alternative is to use the memberOf navigation property:
GET https://graph.microsoft.com/v1.0/users/user-id-here/memberOf
This returns the groups and directory roles the user is a direct member of.
