So from ServiceNow you are calling SCIM integration and want to get Access token?

You can use script to obtain the refresh and access token from script, script will vary based on grant type somewhat

Hi,

Thanks for the response.

I am just trying to get the access token using oauth token with the grant type - client credentials. But am getting error as - 

{

    "error_description": "access_denied",

    "error": "server_error"

}

If you have setup OAuth in ServiceNow and SCIM is using ServiceNow provided OAuth, use below

1. Create OAuth configuration in ServiceNow. Make a note of client ID and client secret to be used in API call

2. Create integration user with web service access to be used for initial OAuth call

3. Make a API call from SCIM to get access token & refresh token. Once refresh token is available, use it to get access token and refresh token for subsequent calls

Please see below for sample API calls from Postman and process is similar for any third-party tool using ServiceNow as OAuth Provider

OAuth Using Refresh Token [subsequent calls once initial refresh token is fetched]
