I want to obtain a token on Microsoft Graph via a GET request.
If I use the following call, I get a login screen asking for username and password.
https://login.microsoftonline.com/common/oauth2/v2.0/authorize?
client_id=f3992025-4d4d-XXXXX-bb2d-XXXXXXXXX
&client_secret=XXXXXXXXXXXXXXXXXXXXXXXXXX
&response_type=code
&redirect_uri=https://10.100.XXX.XXX:5858/authorize
&response_mode=query
&scope=openid%20offline_access%20https%3A%2F%2Fgraph.microsoft.com%2Fmail.read
&state=12345
if I do so, i do I get the code necessary to later obtain the token and I can use it no without issues
My problem is that I don't want to that login screen. I want the request to return the code without user interaction. I thought that the client_id and client_secret would take care of this.
I am following this directions: https://developer.microsoft.com/en-us/graph/docs/concepts/auth_overview
Thank you.
As far as I know, you can use OAuth 2.0 client credentials grant to access web-hosted resources by using the identity of an application.It's is used for server-to-server interactions.For more information, please click https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-client-creds-grant-flow.
POST https://login.microsoftonline.com/{tenant}/oauth2/v2.0/token
client_id=f3992025-4d4d-XXXXX-bb2d-XXXXXXXXX
&scope=https://graph.microsoft.com/.default
&client_secret=XXXXXXXXXXXXXXXXXXXXXXXXXX

I am trying to create meeting on behalf of a user for that I am trying to get the code. I have registered the app on Azure. Also generated Application(Client) ID I have also added the required permission in the API. But when I am visiting this page the page asks for the email id but once the users fill the email id it says The provided value for the input value scope is not valid for OnlineMeeting.ReadWrite in the redirect URL.
Please guide me to know what I am missing here.
Edit 1: As suggested by #Rukmini I tried this and here is the relevant details.
To obtain the the code I am building url like this image
This does not work when I pass the OnlineMeetings.ReadWrite scope. But when I pass https://graph.microsoft.com/.default as scope it works and I am able to authenticate and generate a code. Then I can use that code to get the access token like following image. But using this access token I can not create the meeting as it does not have the OnlineMeetings.ReadWrite scope as stated in this doc **https://learn.microsoft.com/en-us/graph/api/application-post-onlinemeetings?view=graph-rest-1.0&tabs=http**[![enter image description here]3]3
Let me know what I can do to generate code and access token for the OnlineMeetings.ReadWrite scope so that I can create the meeting on users behalf. Thanks
EDIT 2: I generated the authorization URL as suggested by #Rukmini using the following query parameters.
When I visited the link, I was presented with a login screen but as my previous error I see the same screen. Am I missing something here? Do I need to verify my app? Or Do I have to only use some specific IDs like we do in GCP and AWS?
Please let me know what I am missing here.
Thanks
I tried to reproduce the same in my environment and got the results successfully like below:
I created an Azure AD Multi-Tenant Application:
I granted Admin Consent to the API permissions like below:
I generated the code by using below endpoint and authorizing it via browser:
https://login.microsoftonline.com/common/oauth2/v2.0/authorize?
&client_id=ClientID
&response_type=code
&redirect_uri=https://jwt.ms
&response_mode=query
&scope=OnlineMeetings.ReadWrite
&state=12345
Now, I generated access token by using the below parameters:
https://login.microsoftonline.com/common/oauth2/v2.0/token
client_id:ClientID
client_secret:ClientSecret
scope:OnlineMeetings.ReadWrite
grant_type:authorization_code
redirect_uri:https://jwt.ms
code:code
Decode the access token using jwt.ms and check whether the scope is OnlineMeetings.ReadWrite:
I am able to create the Online meetings successfully by using the below query:
https://graph.microsoft.com/v1.0/me/onlineMeetings
Content-Type: application/json
{
"startDateTime":"2023-01-12T14:30:34.2444915-07:00",
"endDateTime":"2023-02-12T15:00:34.2464912-07:00",
"subject":"User Token Meeting"
}
In my java web application I want to get access to user's mailbox by using jakarta mail. For that purpose I followed https://learn.microsoft.com/en-us/exchange/client-developer/legacy-protocols/how-to-authenticate-an-imap-pop-smtp-application-by-using-oauth for OAuth2 authorization code flow.
On Azure port I setup my app and added API permissions as below
Now user is redirecting to below authorize endpoint:
https://login.microsoftonline.com/5426ee07-9b73-4a9e-8075-395ab439c6fa/oauth2/v2.0/authorize?client_id=b6067ad9-7195-430b-a35d-97b7aa7beb8f&response_type=code&redirect_uri=http://localhost:8080/callback/microsoft&response_mode=query&scope=offline_access%20https%3A%2F%2Fgraph.microsoft.com%2FIMAP.AccessAsUser.All%20https%3A%2F%2Fgraph.microsoft.com%2FSMTP.Send
After entering credentials and accepting the consent redirect_uri gets hit with auth code. Based on that auth code I formed token endpoint URL and hitting it from server, the token endpoint is as follow:
URL: https://login.microsoftonline.com/5426ee07-9b73-4a9e-8075-395ab439c6fa/oauth2/v2.0/token
Form Data:
client_id=b6067ad9-7195-430b-a35d-97b7aa7beb8f
scope=offline_access%20https%3A%2F%2Foutlook.office.com%2FIMAP.AccessAsUser.All
redirect_uri=http://localhost:8080/callback/microsoft
grant_type=authorization_code
client_secret=QUs8Q~aboLBiopTezMTKwzQjIwWsFFXjc2kCRaRs (I know I have shared the secret)
code={code received from authorize end point}
Response to this post request comes as:
{"error":"invalid_grant","error_description":"AADSTS65001: The user or administrator has not consented to use the application with ID 'b6067ad9-7195-430b-a35d-97b7aa7beb8f' named 'Email Connector'.

Here, I don't understand why the error is saying The user or administrator has not consented to use the application, user has accepted the consent after entering credentials on authorize end point. Event more If we look at the screenshot above admin has already given grant to access the directory.
I tried to reproduce the same scenario in my environment and got the same error as below:
To resolve the error, please check the authorize endpoint you are using to get the code.
Avoid using Microsoft graph API scopes while getting the code.
Replace it with the scope you are using to get access token like below:
https://login.microsoftonline.com/Your_TenantID/oauth2/v2.0/authorize?
client_id=Your_ClientID
&response_type=code
&redirect_uri=http://localhost:8080/callback/microsoft
&response_mode=query
&scope= offline_access https://outlook.office.com/IMAP.AccessAsUser.All
&state=12345
Get the code from the above authorization endpoint.
I got the access token successfully after modifying the endpoint like below:
To validate the access token decode it in jwt.io and check the aud and scp claims like below:
I have error "Access token validation failure. Invalid audience."
For application set api permissions to offline_access, openid, profile, User.Read.
User start auth, go to MS auth site, ask about login, password and grand.
After exchange code to access token i well receive
{'token_type': 'Bearer', 'scope': 'offline_access openid profile User.Read', 'expires_in': '3906', 'ext_expires_in': '3906', 'expires_on': '1653988700', 'not_before': '1653984493', 'resource': 'my_azure_client_id', ....}
Then i try get profile for current user with this access token.
As result i have error "Access token validation failure. Invalid audience."
Help pease)
UPDATE
Configured permissions
The reason behind getting that error is because your token has wrong audience.
Please check what token you are using to call Graph API.
I tried to reproduce the same in my environment.
If you are using ID Token instead of Access Token, you may get error like below:
To know whether you are giving access token or id token, decode it in JSON Web Tokens - jwt.io.
For access token, aud claim will be "https://graph.microsoft.com" or "00000003-0000-0000-c000-000000000000"
For id token, aud claim will be "your_app_client_id"
Choose the access token carefully with aud as "https://graph.microsoft.com" while calling Microsoft Graph API:
To get profile for current user, you can make use of below query:
GET https://graph.microsoft.com/v1.0/me
I got the profile successfully using access token like below:
Replace your scope with https://graph.microsoft.com/.default while generating access token to avoid confusion.
Reference:
oauth 2.0 - Microsoft Graph API: Access token validation failure. Invalid audience - Stack Overflow
UPDATE:
In order to get authorization code, make the request by changing scope like below:
https://login.microsoftonline.com/your_tenant_id/oauth2/v2.0/authorize?
client_id=your_client_id
&response_type=code
&redirect_uri=xxxxxx
&response_mode=query
&scope=https://graph.microsoft.com/.default
&state=12345
I have my confidential client and resource client registered in AAD.
The confidential client has API permissions to access the resource client.
After I logged in from the confidential client with my credentials how can I can make a request to the resource client?
Based on the ms docs
For example, if your web API's application ID URI is https://contoso.com/api and your scope name is Employees.Read.All, the full scope is:
https://contoso.com/api/Employees.Read.All
The example is not enough for me to understand like where's the access token?
You could use auth code flow to obtain the access token.
First, get code by the url in your browser. You need to login in this step.
https://login.microsoftonline.com/{tenant}/oauth2/v2.0/authorize?
client_id={your-client-id}
&response_type=code
&redirect_uri=http%3A%2F%2Flocalhost%2Fmyapp%2F
&response_mode=query
&scope=https://contoso.com/api/Employees.Read.All
&state=12345
Then, get access_token with the code.
POST https://login.microsoftonline.com/{tenant}/oauth2/v2.0/token
Content-Type: application/x-www-form-urlencoded
client_id={your-client-id}
&scope=https://contoso.com/api/Employees.Read.All
&code={the code from the previous step}
&redirect_uri=http%3A%2F%2Flocalhost%2Fmyapp%2F
&grant_type=authorization_code
&client_secret={your-client-secret}
About implicit grant flow:
This flow is usually used for single-page apps, and the implicit grant presents more risks than other grants. Please check if the implicit grant is suitable for your app, see here. If not, I still recommend you use auth code flow.
Note: To let it work, you need to select access tokens under the Implicit grant section in the portal first, navigate to App registrations -> your application -> Authentication.
https://login.microsoftonline.com/{tenant}/oauth2/v2.0/authorize?
client_id={your-client-id}
&response_type=token
&redirect_uri=http%3A%2F%2Flocalhost%2Fmyapp%2F
&scope=https://contoso.com/api/Employees.Read.All
&response_mode=fragment
&state=12345
&nonce=678910
&prompt=none
I am making OAuth 2.0 auth code authentication flow with multi-tenant application.
Here is my authorize url:
https://login.microsoftonline.com/common/oauth2/v2.0/authorize?client_id=my_id&prompt=consent&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fauthorize&response_type=code&scope=openid+offline_access&state=17
It goes fine and I receive auth_code. Then I make request with this auth_code to token_url and receive a lot of information, like:
token_type
scope
id_token
access_token
refresh_token
expires_at
ext_expires_in
Seems fine to me, but when I make request on API with access_token like:
https://management.azure.com/subscriptions/my_sub_id/locations?api-version=2016-06-01
with headers:
Content-Type:
- application/json
Authorization:
- Bearer EwBQA8l6BAAURSN/FHlDW5xN74t6GzbtsBBeBUYAAV1IHgHb4dOWblzfd/YsSuFicAMDYbua17QivnAT9/pIaeKAg3uKsK5VGqWLzjMOUQrCpd7R1RAM6RkzI0u8e4rpO7DISG7qLso5H5+U1jb+38/j1urcwlXMMxhy83ZXmdpkLXpZV+vcOV...
It responds with 401 error
body:
encoding: UTF-8
string: '{"error":{"code":"InvalidAuthenticationToken","message":"The access token is invalid."}}'
To be honest I think something wrong with my access_token. It seems not like JWT for me. Documentation says it looks like:
"access_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsIng1dCEV1Q..."
But my access_token looks like:
"access_token": "EwBYA8l6BAAURSN/FHlDW5xN74t6GzbtsBBeBUYAAZDe7JE/MPLoAi+Fr+1Xxq5eBe5N9l8Q+c4QjkY5PGEzRnBpPe7+v6h+PLdh1cceBQx+/JsB2QCrYSCt7x/zGsQAhwoY/"
Is it fine?
Here is my permissions for application:
Permissions
The main issue you have here is that you have only asked for an access token for the scopes openid offline_access. The resulting access token will be for Microsoft Graph (https://graph.microsoft.com), not for the Azure REST API (https://management.azure.com).
To indicate you would like a token for a given API, the scope parameter in your authorization request should include the delegated permission you would like the app to have for the API. In the case of Azure REST API, there's only one delegated permission: user_impersonation. The identifier URI for the Azure REST API is https://management.azure.com, so the scope value you want to use is:
openid offline_access https://management.azure.com/user_impersonation
Two more important notes:
As you've discovered, you will not always be issued an access token as a JWT which you can decode peek at. The format of the access token is an agreement between the service which issued the token (Azure AD or Microsoft Accounts, in this case), and the service for which the token was issued (Microsoft Graph, in this example).
You should not always include prompt=consent. prompt=consent should only be used if you have already tried signing in the user without the user needs to be re-prompted for consent for a new permission.
If you simply include the required scopes in the scopes parameter, the Microsoft Identity platform will take care of figuring out if it needs to prompt for consent or not. If you always include prompt=consent, you will find that many organizations will be blocked from accessing your app, because they've disabled the ability for users to grant consent themselves (and this parameter specifically states that you require the user to be prompted again).
