Azure monitor REST API throwing invalid token error

Question

I created a native APP with Client credentials

 AuthenticationContext authContext = new AuthenticationContext(AUTHORITY, false, service);
            ClientCredential clientCred = new ClientCredential(CLIENT_ID, "myclientsecret");
            //Future<AuthenticationResult> future = authContext.acquireToken("https://graph.microsoft.com", clientCred, null);
            Future<AuthenticationResult> future = authContext.acquireToken("https://graph.microsoft.com", clientCred, null);

Authority is:

login.microsoftonline.com/{tenetID}/oauth2/authorize/

This worked fine and got a access token. Then I tried to access Azure Management REST API by setting this token as Bearer Token. Getting

401 Unauthorized

WWW-Authenticate: Bearer authorization_uri="https://login.windows.net/{tenentid}", error="invalid_token", error_description="Could not find identity for access token."

Any idea what am I doing wrong?

Hello AzureSight,

Your code is correct, except that you are trying to acquire a token for Graph API instead of Azure Management API

Please replace the resource endpoint - https://graph.microsoft.com with https://management.core.windows.net

Do let us know if you face any issues.
