feedLabel property

The feed label that is specified on the data source level.

Must be less than or equal to 20 uppercase letters (A-Z), numbers (0-9), and dashes (-). See also migration to feed labels. feedLabel and contentLanguage must be either both set or unset for data sources with product content type. They must be set for data sources with a file input. The fields must be unset for data sources without file input. If set, the data source will only accept products matching this combination. If unset, the data source will accept produts without that restriction.

Optional. Immutable.
