The Remove Customization API allows you to delete a customization entity from the system. To use this API, you must provide the customization_id of the customization entity you wish to delete. Upon successful deletion, the customization entity and its associated service configurations will be permanently removed from the system. This API is useful for managing and maintaining your customization entities, enabling you to remove outdated or unused customizations as needed. It is important to use this API with caution, as the deletion of a customization entity is irreversible and cannot be undone.
