client-id - A unique ID that represents the system app, and is required for OpenID Connect authentication flows.
client-secret - An app-specific secret that allows fabric Identity to validate the system app. This secret is mandatory for system apps to integrate with fabric Identity.
Authorization Url - The fabric Identity HTTP endpoint that the system app communicates with to get its access token. Every fabric merchant is provided with a unique URL.
 Currently, fabric customers don’t have a self-service capability to create the system app and get the 
client-id, client-secret, and Authorization Url by themselves. Contact fabric support for help in creating these.
