OIDC Azure AD token?

I am trying to configure a third party web application to use Azure AD as the OIDC provider. The authentication works fine, however I am looking for some claims and not able to find an ID or Access Token. Here is the flow as I am seeing it

  1. Call to the login page of the web application. This gets a 302 redirect to the Microsoft OAuth endpoint as below

  2. The URL is https://login.microsoftonline.com/-tenantid-/oauth2/v2.0/authorize?client_id=-clientid-&redirect_uri=-encodedCallbackURI-&response_type=code&scope=openid+email+profile&state=123 This does a 302 to below URL

  3. Next call is to https://login.microsoftonline.com/-tenantid-/oauth2/v2.0/authorize?client_id=-clientid-&redirect_uri=-encodedCallbackURI-&response_type=code&scope=openid+email+profile&state=123&**sso_nonce=O.eyJ0eXAiOiJK......**&client-request-id=-guid-&mscrid=-guid- This returns a 200

  4. Next is the redirect back to the hosted web application indicated in teh callback - https://webApplicationURL/callback?code=0.AQ4Ayjxg80......&state=123&session_state=5b7c2e43-9eab-4bb1-9f24-d020f144d30d

At this point, the user has successfully been authenticated. However, I would like to find the ID or Access Token received.

The sso_nonce(in #3) is in a JWT format but has no claims.

The code(in #4) doesn't have any of the claims either and doesnt really seem to be a JWT token format.

So where is the ID Token or Access Token that I can use to decode and see what claims are getting passed (or not)?

Thanks in advance,

Jake.

To get tokens while calling login page of the web application, you can execute the below request in browser by including response_type as id_token+token:

https://login.microsoftonline.com/<tenant_ID>/oauth2/v2.0/authorize?
client_id=da5daf42-xxxx-xxxx-xxxxxx04a52 //your AppID
&response_type=id_token+token   //Required                    
&redirect_uri=https://jwt.ms   //your Redirect URL  
&response_mode=fragment                            
&scope=openid+profile+email                           
&state=12345                                          
&nonce=678910

Make sure to enable tokens for your web application before executing the above request like below:

Go to Azure Active Directory -> App Registrations -> Your App -> Authentication -> Enable tokens -> Save

I tried to reproduce the same in my environment and got the below results:

When I executed the above-mentioned request in the browser, it asked me to sign in like below:

After successful sign-in, it took me to the redirect URL with tokens in the address bar like below:

When you copy-paste the above in Notepad or any, you can find both access_token and id_token like this:

I got the claims successfully when I decoded the token like below:
