Hi Sam, Feeds are essentially tables which will have columns which are referred to as FeedAttributes and each row in this table which is referred as FeedItem. A sample use case would be, if you wish to display your Ads with the sitelinks of different sections of your page, that is when you choose to set up Feeds.
The FeedItems could be enabled at different levels like customer's entire account or at a campaign level or at an AdGroup level. Deciding at which level the feed should be enabled is based on the data in your feed and the level of control you want. Please check here <https://developers.google.com/adwords/api/docs/guides/feed-services#campaignfeedservice> for more details. Once you apply the FeedItems at an AdGroupLevel, it will be applicable for all the Ads in that specific AdGroup. You can only have one Feed associated with an AdGroup for a given PlaceHolderType <https://developers.google.com/adwords/api/docs/appendix/placeholders>. If you are attempting to add more than one Feed at an AdGroup level with the same PlaceHolderType, you will get the error : FEED_ALREADY_EXISTS_FOR_PLACEHOLDER_TYPE <https://developers.google.com/adwords/api/docs/reference/v201702/AdGroupFeedService.AdGroupFeedError.Reason> . You could use FeedItemService <https://developers.google.com/adwords/api/docs/reference/v201702/FeedItemService>, if you need to enable specific feedItems at the AdGroupLevel. This will help you filter which FeedItems (rows) apply to the specific ad group using a matching function. You can check this <https://developers.google.com/adwords/api/docs/guides/feed-services#feeditemservice> section for more details. If you are interested, you can find the code samples here <https://developers.google.com/adwords/api/docs/guides/feed-services#source> .
