OpenRtbEcto.V3.BidRequest.Source (OpenRtbEcto v0.1.3) View Source

This object carries data about the source of the transaction including the unique ID of the transaction itself, source authentication information, and the chain of custody.

NOTE: Attributes ds, dsmap, cert, and digest support digitally signed bid requests as defined by the Ads.cert: Signed Bid Requests specification. As the Ads.cert specification is still in its BETA state, these attributes should be considered to be in a similar state.

Attribute         Type                     Definition
tid string; recommended Transaction ID that must be common across all participants throughout the entire supply chain of this transaction. This also applies across all participating exchanges in a header bidding or similar publisher-centric broadcast scenario.
ts integer; recommended Timestamp when the request originated at the beginning of the supply chain in Unix format (i.e., milliseconds since the epoch). This value must be held as immutable throughout subsequent intermediaries.
ds string; recommended Digital signature used to authenticate the origin of this request computed by the publisher or its trusted agent from a digest string composed of a set of immutable attributes found in the bid request. Refer to Section “Inventory Authentication” for more details.
dsmap string An ordered list of identifiers that indicates the attributes used to create the digest. This map provides the essential instructions for recreating the digest from the bid request, which is a necessary step in validating the digital signature in the ds attribute. Refer to Section “Inventory Authentication” for more details.
cert string; recommended File name of the certificate (i.e., the public key) used to generate the digital signature in the ds attribute. Refer to Section “Inventory Authentication” for more details.
digest string The full digest string that was signed to produce the digital signature. Refer to Section “Inventory Authentication” for more details.
NOTE: This is only intended for debugging purposes as needed. It is not intended for normal Production traffic due to the bandwidth impact.
pchain string Payment ID chain string containing embedded syntax described in the TAG Payment ID Protocol.
NOTE: Authentication features in this Source object combined with the “ads.txt” specification may lead to the deprecation of this attribute.
ext object Optional exchange-specific extensions.
