I am trying (and failing) to use OAuth2 to make calls to the admin.directory.group scope via a command line script. I tried configuring a Service Account to do this, but get this error message:
Error calling GET https://www.googleapis.com/admin/directory/v1/groups/foo%40example.com: (403) Not Authorized to access this resource/api
I also tried using an "Installed" application type, taking the manual step of obtaining an authorization code and subsequently a refresh token, but got the same Not Authorized error.
I do have "Enable API access" checked, and also have "Admin SDK" enabled in my project (though oddly it doesn't list admin.directory.group as one of Admin SDK's scopes).
What am I doing wrong?
Have you add the client ID in your Admin Console to grant Admin SDK third party client oauth access?
Here is an instruction on how to do that for task API:
https://developers.google.com/google-apps/help/articles/2lo-in-tasks-for-admins#manage
It should be similar for Admin SDK except you will have to put Admin SDK as the scope
I finally got this to work using a service account. I did have to grant 3rd party access as Emily Lam suggested, but by a different means:
Log in to admin console
Security -> Advanced settings -> Authentication ->
Mange third party OAuth Client access
Authorize a new client by setting the Client Name to the Client ID of the service account, and the the API scope to whatever you need from the Admin SDK (e.g., https://www.googleapis.com/auth/admin.directory.group)
The other thing I needed to do was make sure my request was being made on behalf on an administrative user. Using the PHP API, setting up the credentials object looks like this:
$cred = new Google_Auth_AssertionCredentials(
$clientEmail,
'https://www.googleapis.com/auth/admin.directory.group',
file_get_contents($keyFile));
$cred->sub = 'admin#example.com';
Now I am able to successfully make calls using the Google_Service_Directory class.

We are integrating the Role Assignments - List API from Microsoft Azure Cloud Management APIs, Link to documentation: https://learn.microsoft.com/en-us/rest/api/authorization/roleassignments/list#errordetail
We have done all of the configs mentioned:
Registered a multi-tenant web app with Azure Active Directory for OAuth using App Registrations option,
Also enabled the https://management.azure.com/user_impersonation scope under Azure Service Management
Same scope is requested by the web app
So far OAuth succeeds but the access token received when used to call an API GET https://management.azure.com/subscriptions/{subscriptionId}/providers/Microsoft.Authorization/roleAssignments?api-version=2015-07-01 it fails with 401 Unauthorized error. I have replaced the subscriptionId with the appropriate value while making actual call.
I looked at the details of access token using https://jwt.io/ and the scp element only seems to have "scp": "User.Read" scope, Missing the user_impersonation. Though the AUTH dialog from Microsoft login service shows clearly the requested user_impersonation grant. The user account I am using for the OAuth has access to the given azure subscription.
What might be the problem?
It's important to add scope with https://management.azure.com/user_impersonation when requesting for an access token.
Test using implicit grant flow in browser:
https://login.microsoftonline.com/<tenant-id>/oauth2/v2.0/authorize?
client_id=<your-app-id>
&response_type=token
&redirect_uri=<your-redirect_uri>
&scope=https://management.azure.com/user_impersonation
&response_mode=fragment
&state=12345
&nonce=678910
Note: If you use client credentials flow, change scope to https://management.azure.com/.default.
We are experiencing problems with Authentication of Service Accounts for domain-wide delegation.
The main problem is it's hard to investigate and debug the auth configuration so
we would like to ask for some tips how to debug the configuration.
Or maybe we are missing some configuration options and you can point us to them.
Our process is:
Create SA(=Service Account) with enabled domain-wide delegation.
Authenticate SA in GSuite admin console(https://support.google.com/a/answer/162106?hl=en).
use client_id from the credentials file. (now email)
scopes are comma-separated without spaces between.
Ensure the "Security > API Reference > API Reference -> 'Enable API Access'" is checked.
For some GSuite domains this is working configuration, but we got some domains where this configuration results in:
google.auth.exceptions.RefreshError: ('unauthorized_client: Client is unauthorized to retrieve access tokens using this method.', '{\n "error": "unauthorized_client",\n "error_description": "Client is unauthorized to retrieve access tokens using this method."\n}')
In our understanding, this is the error saying the client_id and scopes were not added to the "Manage API client access" page. (=List of authenticated clients)
We really ensured that the GSuite domain we are requesting has the proper client_id and scopes added in the list of authenticated clients + has the 'Enabled API Access'.
We even created Shared Desktop with them and did it by ourselves to be fully sure of it.
But the error still persists.
However, we are not able to replicate this problem on our test GSuite domain.
We tried couple of options using same SA as the client:
The impersonated account hasn't permissions to access the resource.
This result in:
googleapiclient.errors.HttpError: https://www.googleapis.com/admin/directory/v1/users?customer=my_customer&alt=json returned "Not Authorized to access this resource/api">
The scopes are just partial:
google.auth.exceptions.RefreshError: ('access_denied: Requested client not authorized.', '{\n "error": "access_denied",\n "error_description": "Requested client not authorized."\n}')
The 'Enabled API Access' is not checked.
googleapiclient.errors.HttpError: https://www.googleapis.com/admin/directory/v1/users?customer=my_customer&alt=json returned "Domain cannot use apis.">
The error we are receiving from the client("Client is unauthorized to retrieve access tokens using this method."), we are able to replicate only if the client_id is not in the list of authenticated clients at all.
But we are sure, the problematic GSuite domains have the SA authenticated in "Manage API client access" page.
We are using these scopes: https://www.googleapis.com/auth/userinfo.profile,https://www.googleapis.com/auth/userinfo.email,https://www.googleapis.com/auth/gmail.readonly,https://www.googleapis.com/auth/plus.login,https://www.googleapis.com/auth/calendar.readonly,https://www.googleapis.com/auth/contacts.readonly, https://www.googleapis.com/auth/admin.directory.user.readonly
Do you have any ideas how to debug/solve this issue?
Here is what you need to do. Double check each step. If in doubt, start over.
Enable "Admin SDK API. This is enabled on a per project basis.
Create a service account. Do not add or remove any privileges. Don't change the service account in any way. If you do you will get an error that you are not authorized.
Enable Domain-wide Delegation on the service account.
Follow this document to delegate domain-wide authority to your service account:
Delegate domain-wide authority to your service account
When creating the service account credentials (from the downloaded Json) you will need the following scopes for full G Suite management:
"https://www.googleapis.com/auth/admin.directory.group",
"https://www.googleapis.com/auth/admin.directory.user"
Impersonate a user account which creates new credentials. The user account needs to be a G Suite superadmin. This account must have logged into G Suite at least once and accepted the Terms of Service.
Create your client using the credentials from step #5.
Working Python Example:
from googleapiclient.discovery import build
from google.oauth2 import service_account
# This is the service account credentials file
credentials_file = 'google-directory-api.json'
# In this example I only need to send email
credentials = service_account.Credentials.from_service_account_file(
credentials_file,
scopes=['https://www.googleapis.com/auth/gmail.send'])
# This user is a G Suite superadmin
impersonate = 'username#example.com'
credentials = credentials.with_subject(impersonate)
service = build('gmail', 'v1', credentials=credentials)
I think we are going to need to take this in stages. Lets start with your first error and see if that fixes your issue.
Background info
There are several types of clients that you can create in Google developer console. Here are the top three.
Browser client: Used for web applications
Native client (other): used for installed desktop applications
Service account: used for server to server communication.
The clients are different the client.json file you download is different and the code used to authenticated to the authentication server is also different.
Error 1: code / client missmatch
unauthorized_client: Client is unauthorized to retrieve access tokens using this method.
Can mean one of two things. Either you have created a service account client and you are not using service account code to authenticate or you are are using the code to authenticate with a service account but you have not created a service account client. You haven't posted what language you are using or any code so I cant tell you if the code you are using is intended to be used with a service account or not. Your going to have to look into this one a bit.
Check in developer console make sure your client is like this If it is check your code. If it isnt then create a real service account client and try again.
I'm following https://aws.amazon.com/blogs/security/how-to-set-up-federated-single-sign-on-to-aws-using-google-apps/ and attempting to set up a script to patch my Google users with SSO AWS roles.
Using the scope listed at https://developers.google.com/admin-sdk/directory/v1/reference/users/patch , I've authenticated properly and have confirmed by doing a simple:
service.users().list(customer='my_customer', maxResults=10, orderBy='email').execute()
This returns successfully with a list of users. However, when I try to execute a patch query with:
service.users().patch(body=body, userKey=user_email).execute()
The response is "Not Authorized to access this resource/api".
Is this endpoint special in some way? It appears the only way to successfully access this resource is by authenticating with a super admin account, which I would prefer not to do.
Please note that it was mentioned in Directory API: Authorize Requests that,
Your application must use OAuth 2.0 to authorize requests. No other authorization protocols are supported. If your application uses Google Sign-In, some aspects of authorization are handled for you.
With this, I suggest that you use Authorizing requests with OAuth 2.0.
You may also check other possibilities why such error can be encountered from these SO posts:
Google_Service_Directory - (403) Not Authorized to access this resource/api
The root of the problem is that the service account is not an administrator on the domain, so it cannot access the Admin SDK Directory API. Instead, you need to enable domain-wide delegation for your service account, and then have the service account impersonate a domain admin when it makes the request.
Google Directory API returns Not Authorized when call users().list().execute()
Hope that helps!
I wrote a PHP application which tries to create an User in my Google Directory. I don't use the Google Libraries. I succeded making requests to the Android Enterprise API. I can enroll and unenroll Enterprise Service Accounts with my MSA. So I assume my Code for the JWT and Requests work.
I created a Service Account and enabled "Domain Wide Delegation" and added the following permission "https://www.googleapis.com/auth/admin.directory.user, https://www.googleapis.com/auth/admin.directory.group" to my API Client under the "Manage API client access" windows.
My Service Account has the status role "Editor" in the "Permissions for project" windows.
So first my script gets the Bearer token from the Google Server, for that I create a JWT and encrypt it with my private key.
The Token contains the following fields
"iss" => sacname#projectname.iam.gserviceaccount.com
"scope" => "https://www.googleapis.com/auth/admin.directory.user, https://www.googleapis.com/auth/admin.directory.group"
"aud" => "https://www.googleapis.com/oauth2/v4/token",
"exp" => timestamp+3000,
"iat" => timestamp
When I do that request I get a bearer token, but when I use that token to make the insert request I always get the message "Not Authorized to access this resource/api" with an HTTP 403.
When I add the field "sub" to my JWT and specify the email of the Project admin "admin#mydomain.com" I can't even get the bearer token, then I get a 401 error with the following message "Unauthorized client or scope in request."
After that I tried something "easy", I just wanted to get a list of all users in my directory. But the Google Server just reponds with an "bad request" error. I got the same error with the API Explorer which is on API Page. Maybe the API is broken ? At least the API Explorer should work.
https://developers.google.com/admin-sdk/directory/v1/reference/users/list
Do you have some ideas why I can't create users with my service account ?
(I had to insert some spaces in the scopes and urls because I'm not allowed to post more than two links)
Greetings
Philip
Adding the sub claim is the right thing to do, because you must impersonate a super admin to use Directory API. If you get a "Unauthorized client or scope in request" response, that might be because there's a typo in the service account client ID you used to authorize (or the scopes), or that not enough time has passed (it usually propagates within a few minutes, but could take up to 24 hours).
See JWT error codes for more details on possible errors and causes.
Do you have some ideas why I can't create users with my service account?
Yes. Your service account seems to have no authority to create users. Check your Service Account's role in GDC to check if it's Owner, Editor, Viewer,etc. The scope of what they can do depends on that. Watch this Google video for a live demo.
Also, try to read more on Using OAuth 2.0 for Server to Server Applications.
I am trying to build an AzureAD access app. I have to enable this app for external tenants. I have enabled external access on this app and it is configured to use the Graph API also. I have tested the app in the tenant in which it was created and everything(auth+ graph api access) works. Now here is the flow for the external tenant
I take the external tenant user to the grant consent URL of my app, the user(who is an admin of the external tenant) grants the access and i get the correct response
Now i want to get the authorization token for this user, so i take the user through the normal Oauth process via
https://login.windows.net/common/oauth2/authorize
followed by
https://login.windows.net/common/oauth2/token/
At this point Azure throws the following error
{"error":"invalid_grant","error_description":"AADSTS50000: There was an error issuing a
token. AADSTS65005: No permission to access \u0027https://graph.windows.net\u0027

Why this error even when the app has been granted access. I tried to lookup the STS errors
but found no explanation. Any ideas?
[update]
SAML process continues to work for the external tenant however i.e I can use the app for SAML(SSO) login for this external tenant. The problem only seems to be coming for getting access to the graph API.
Try adding &prompt=consent or &prompt=admin_consent to the full authorize URL to re-request the user consent. My experience has been that the consent will be randomly revoked (maybe a bug) and will not ever be automatically re-requested (definitely a bug).
