# `OpenRtbEcto.V3.BidResponse.SeatBid`
[🔗](https://github.com/AppMonet/open_rtb_ecto/blob/v1.4.6/lib/open_rtb_ecto/v3/bid_response/seat_bid.ex#L1)

A bid response can contain multiple `Seatbid` objects, each on behalf of a different buyer seat and each containing one or more individual bids.  If multiple items are presented in the request offer, the `package` attribute can be used to specify if a seat is willing to accept any impressions that it can win (default) or if it is interested in winning any only if it can win them all as a group.
