feedLabel property
Feed label of products to include in the campaign.
Valid feed labels may contain a maximum of 20 characters including
uppercase letters, numbers, hyphens, and underscores. If you previously
used the deprecated sales_country in the two-letter country code (XX)
format, the feed_label field should be used instead. For more
information see the [feed
label](//support.google.com/merchants/answer/12453549) support article.
