Create a system app with fabric Identity and ensure the following details are available before starting the authentication flow.

`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.

Follow [Getting System app Credentials](https://developer.fabric.inc/v3/platform/settings/api-apps/getting-system-app-credentials) guide to obtain your system app credentials.

If you have troubles obtaining `client-id`, `client-secret`, or `Authorization Url`, contact [fabric support](https://support.fabric.inc/hc/en-us/requests/new) for assistance.
