If access token gets expired, what error/code should we expect from ServiceNow?

[dewanpavel]

We are using ServiceNow for authentication for another third party app. We are using oauth token. While using the app, after sometime, we get pop up window comes up for login. I believe this happens because the access token gets expired after certain time. We need to know what code/error ServiceNow sends back when the the access token gets expired?

Hi Dewan,

I believe ServiceNow sends a HTTP 401 error response, something like;

http:/1.1 401 Unauthorized with code: 401

Hi Sergiu

Thanks for your response.

However, I have also noticed ServiceNow logs the following for access token expiration:

Oauth authentication failed for access token:

{access token string}

Can we pass different code for access token expiration or the log entry to the client?

Thanks

Dewan
