When you add a ServiceNow Action card to a flow for the first time, you'll choose which instance to connect. This authorization will be saved and can be reused in other cards.
You can create multiple connections and manage them from your Connections page.
To create a new connection from an action card:
Click New Connection.
In the Connection Nickname field, type your preferred authorization name.
In the Username and Password fields, type your ServiceNow login credentials.
In the Instance field, enter your ServiceNow subdomain value.
You can find the Service Now subdomain value in the Manage > Instance menu in the developer portal or in the instance's URL. For example in https://dev57240.service-now.com/ the instance name will be dev57240.
The service account that you choose for a connection with Okta Workflows must have the following:
Permissions to view the sys_db_object table
A ServiceNow delegated_developer role assigned
To ensure action cards that update ServiceNow incidents such as the Create Incident, Delete Incident, or Search Incidents cards perform as expected, it is required that you add the personalize_dictionary and incident_manager roles to the same ServiceNow account to which the delegated_developer role is also assigned.
