Get Oauth token gives HTTP Error 401 - Unauthorized

Khalnayak · ‎11-17-2020

Hi all,

I have created an app registry for the Service Graph Connector for Microsoft Intune app in ServiceNow.

I have created an app registry in azure too and all the setup looks fine.

But when clicking on Get Oauth token I am getting the HTTP Error 401 - Unauthorized.

I dont know why though, as I have the exact same setup for my dev instance and that is working fine.

Just when setting it up in test it is giving this error.

The only difference between the 2 instances that I know of, is that test is SSO using Azure AD and Dev is not.

When i first clicked Get Oauth token, it asked me to login, then asked for admin approval, which I got an admin user to enter, and after that I am seeing this error.

Can someone advise please?

I had the same issue and this link really helped me. https://www.linkedin.com/pulse/servicenow-outbound-web-services-oauth-20-how-handle-r%C3%A9da-osseili/

The error that SN returned by default is very misleading since it hides the actual detailed error message. We need to add some logs in the script include (OAuthUtil) that parse the get token response, so we can understand the exact issue.

My particular issue was that I was using the wrong client secret. I used the id instead of the actual secret value. Silly me, I know!

Once you enable the log in OAuthUtil, The error message was able to lead me to resolve my issue.

Hope this will help someone in the future.

Thanks for this. Funny how i made this exact mistake now. Used the secret ID instead of secret value.

Same error, like mentioned above the wrong secret was provided.

Hi there,

"I have the exact same setup for my dev instance"

Have you checked the settings within Intune itself? Recently I've been working also on Intune, and you have to specify the exact environment you are granting access too.

Kind regards,

Hi Team,

I am getting the error while accessing Oauth access token from servicenow instance as below

{"error_description":"access_denied","error":"server_error"}

I have created OAuth End Point on another instance having below client_id and client_secret

URL = https://customer_instance.service-now.com/oauth_token.do

client_id = 0fa6dade7b000110abfbf53e56d948ff

client_secret = ]Uvyq{wfz`

Content-type = application/x-www-form-urlencoded

grant_type = password

with username & password

I checked the username and password by using /login.do and it's working so I think my password is correct

Please do the needful
