The NextZen CSV Integration format groups rows that belong together, by gouping rows by id or slug . A slug should be considered a temporary unique identifier and is not persisted after the request.

When known, an id should be used as the unique identifier for grouping, rather than using a slug . In this case the slug is not used and should be empty.

When an id is not known, a slug may be used as a temporary unique identifier for grouping. In this case the id is not used and should be empty. Slugs must be composed of one or more sequences alphanumeric characters, separated by dashes. For example: profile-1 or profile-sue-simmons-example-com .
