It is not possible to get an OAuth Token

I just get the response: {"error_description":"access_denied","error":"server_error"}

 

Here's my view in Application Registries:

As you can see I have a client-id and client-secret set here. Now:

$ curl -XPOST "https://$INSTANCE/oauth_token.do" \
  -H "Accept: application/json" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "grant_type=client_credentials&client_id=$CLIENT_ID&client_secret=$CLIENT_SECRET"
echo

 This should work but instead it is giving me the "access_denied" error.

 

INSTANCE is my "blah.service-now.com" instance hostname. CLIENT_ID and CLIENT_SECRET are from the values shown in my application registry.

Hi @ncastagnet_mc , 

You need to check with the team who has provided that Oauth credentials, the input/output format should match as per SN process. 

 

access_denied, means credentails are not correct or some inputs are missing.

 

-Thanks,

Hi @ncastagnet_mc ,

 

The ServiceNow documentation for using grant type "Client Credential" for inbound requests looks a little different than your setup. You can find the setup here for more inforamtion: https://www.servicenow.com/docs/bundle/xanadu-platform-security/page/integrate/authentication/concep...

 

But it states as below when and how to use client credentials grant type:

 

Use the OAuth client credentials grant type for Inbound Integrations from a third party OAuth client to the ServiceNow® platform.

The administrators can use the client credential (CC) grant type to enable integration from a third party OAuth client to the ServiceNow platform.

Inbound client credentials grant type is a capability that can be controlled through a system property. By default the system property is false.

To use the client credentials grant type, you must perform the following steps:

  • Create the glide.oauth.inbound.client.credential.grant_type.enabled system property.
  • Add the OAuth Application User field to the OAuth Entity form.
