Oauth 2.0 - Access Token

AmanPratapS7233 · 3 weeks ago

Hi All,

I have created a record in Application Registry 3 months back and I have,

Client ID

Client Secret

Token URL - https://<company>test.service-now.com/oauth_token.do

I want to get the access token and I am using Postman but, I am getting this error although it was working in the past.

Error:

{

"error_description": "Received client_credentials grant_type request however integration user is not configured for OAuth:1b7ae3f52b977218deb7f865ce91bf8b",

"error": "unauthorized_client"

}

@AmanPratapS7233

so what got changed?

you must be using some User credentials for getting the token, is that user active and not locked out?

Are these details not enough for getting the access token ?

Hi @AmanPratapS7233

To resolve this error, you need to enable the Client Credentials grant type at the system level and explicitly assign an integration user to your OAuth application in the App Registry.

Do the following steps /validate your implemented steps as per KB.

Refer KB: KB1645212 How to configure Client Credentials grant type for inbound OAuth

Enable the Client Credentials grant type

Go to System Properties > All Properties.
Select New.
Complete the following fields:
- Name: glide.oauth.inbound.client.credential.grant_type.enabled
- Type: true | false
- Value: true
Select Save.

Configure the OAuth application

Go to System OAuth > Application Registry.
Select New.
Select Create an OAuth API endpoint for external clients.
Enter a name for the application.
In the Default Grant Type field, select Client Credentials.
In the OAuth Application User field, select the integration user to associate with this application.
Select Save.

Test the configuration

To verify the configuration, use Postman or an equivalent API testing tool to request an access token using the Client Credentials grant type.
