Prerequisites

Before you create the OAuth app, make sure the required system property exists and is enabled.

1. In the Application Navigator, enter:
   sys_properties.list
   and press Enter. This opens System Properties > All Properties.
2. Search for the property:
   glide.oauth.inbound.client.credential.grant_type.enabled
3. Confirm that the property exists and is enabled (its value is set to true).

If the system property is missing:

1. Select New.
2. Enter the following values:
• Name: glide.oauth.inbound.client.credential.grant_type.enabled
• Type: Boolean
• Value: true
3. Select Save.

This property allows the instance to accept OAuth client credentials grant type requests.

Step 1: Open the Application Registry

1. Log in to your ServiceNow instance with an account that has admin privileges.
2. Ensure the scope is set to Global.
3. In the Application Navigator, search for “Application Registry,” then select Application Registry.

Step 2: Create a new OAuth application

1. On the Application Registry page, select New.
2. Select Create an OAuth API endpoint for external clients.

3. In the form, enter or verify the following fields:

If you don’t see Default grant type or OAuth application user, you need to update the form layout:

1. Select the gear icon (form layout).
2. Add the missing fields (such as Default grant type and OAuth application user) to the form.

Step 3: Save and note the credentials

1. Select Submit to save the OAuth application.
2. Confirm that the new OAuth app appears in the Application Registry list.
3. Open the record and note the generated Client ID and Client secret. You’ll use these in Snow Integration Manager.

Step 4: Configure Snow Integration Manager

1. In Snow Integration Manager, open the ServiceNow connector configuration.
2. Enter the following values:
• ServiceNow URL: https://<your_instance>.service-now.com
• Client ID: paste the Client ID from the OAuth app
• Client secret: paste the Client secret from the OAuth app
3. Select Test to verify that authentication is successful.

Additional notes

• In Yokohama, the UI differs slightly from the Zurich release. If fields are missing, confirm you’re in the correct scope and adjust the form layout.
• If authentication fails in Snow Integration Manager, use Postman first to verify that the OAuth token request succeeds with the same Client ID, Client secret, and token URL.
