ServiceNow API using Client credentials

[BlinkOps]

Hey. 

I'm trying to to use the /oauth_token.do endpoint with client credentials:
grant_type=client_credentials
client_id+client+secret , and getting access denied. is it supported to authenticate with just client id+secret? 
if i add the username+password it works. (grant_type=password) 
but following the doc's its suppose to work with client id+secret alone. ->

Anyone has any idea?

Hi,

It works with client id and client secret. 

Follow this documentation to make it work - https://www.servicenow.com/docs/bundle/xanadu-platform-security/page/integrate/authentication/concep...

Hi, thank you for your reply.

I followed the client credentials guide, created the system property:

But, when setting the app, I don't have the OAuth Application User field I should see according to the documentation.
Application Registries (what I use):

OAuth OICD Entity (I don't use that but I don't have it here as well):

Still getting access denied. 

I'm using a dev account, maybe it's related?

Hi

Screenshots are not visible. Can you try to attach again and configure the Application registries form layout to add Oauth application user field
