Bid Params

Name Scope Description Example Type

The Relay Bid Adapter makes requests to the Relay Exchange API which supports OpenRTB.

Therefore the only bid param required is the the accountId, all Prebid Ad Unit fields will be automatically inferred via Prebid’s ORTB Converter. If any field on the request requires customization it is configurable using First Party Data - Prebid.js via ortb2 interface. We support all FPD fields:,,,

"Send All Bids" Ad Server Keys

These are the bidder-specific keys that would be targeted within GAM in a Send-All-Bids scenario. GAM truncates keys to 20 characters.
