This Callback URL is created by taking the GUID from the Identity Provider and adding it to the base Callback URL.

The [IdentityProviderUniqueID] must be replaced with the ALL UPPERCASE GUID from your Identity Provider record. [Domain] must be replaced with your church's base URL (for example, https://my.churchname.net).

https://[Domain]/ministryplatformapi/oauth/callback/[IdentityProviderUniqueID]

You will use this in Identity Provider Settings.
