Seat Bid Object

Formally there can be multiple bids within the Seat Bid object for two reasons.

  • There can be several slots in each bid request.

  • There can be more than one bid for a single slot.

BidSwitch allows no more than two bids for a single ad slot. Bids belonging to the same seat must be in the same array, i.e. all values must be unique per response.

Array of Bid Objects, see Bid Object. The maximum number of bid objects per single bid request ad slot is two.



The seat ID of the bidder on whose behalf this bid is made. The value should match one of the values supplied in the wseat field of the bid request. For example, "34".

  • This field is always required in responses, unless you have your account setup for single-seat responses, see the Seat ID and Agency Mapping section for more details about that.

  • Some Suppliers expect their Buyers to respond with their Seat ID rather than BidSwitch’s ID, see the Seat Self-Management for a list o those Suppliers.
