About the authorization callback URL in Apple Business Manager
In Apple Business Manager, you use the authorization callback URL to contact the SCIM app setup in the identity provider (IdP). This URL is different for each IdP and may contain the name of the SCIM app. For example:
https://identity-provider.com/admin/app/AppleBusinessManagerSCIM/oauth/callback
To create an authorization callback URL, see Create the authorization callback URL.
For more information about the exact authorization callback URL, consult your IdP’s documentation.
