Ext json.RawMessage `json:"ext,omitempty"`
}
Item object represents a unit of goods being offered for sale either on the open market or in relation to a private marketplace deal. The id attribute is required since there may be multiple items being offered in the same bid request and bids must reference the specific item of interest. This object interfaces to Layer-4 domain objects for deeper specification of the item being offered (e.g., an impression).
type LossReason ¶
type LossReason int64
LossReason represents OpenRTB Loss Reason Code enumeration.
It lists the options for an exchange to inform a bidder as to the reason why they did not win an item.
const ( LossWon LossReason = 0 // Bid Won LossInternalError LossReason = 1 // Internal Error LossExpired LossReason = 2 // Impression Opportunity Expired LossInvalidResponse LossReason = 3 // Invalid Bid Response LossInvalidDealID LossReason = 4 // Invalid Deal ID LossInvalidAuctionID LossReason = 5 // Invalid Auction ID LossInvalidAdvertiserDomain LossReason = 6 // Invalid Advertiser Domain LossMissingMarkup LossReason = 7 // Missing Markup LossMissingCreativeID LossReason = 8 // Missing Creative ID LossMissingBidPrice LossReason = 9 // Missing Bid Price LossMissingApproval LossReason = 10 // Missing Minimum Creative Approval Data LossBelowAuctionFloor LossReason = 100 // Bid was Below Auction Floor LossBelowDealFloor LossReason = 101 // Bid was Below Deal Floor LossLostToHigherBid LossReason = 102 // Lost to Higher Bid LossLostToDealBid LossReason = 103 // Lost to a Bid for a Deal LossSeatBlocked LossReason = 104 // Buyer Seat Blocked LossCreativeFiltered LossReason = 200 // Creative Filtered - General; Reason Unknown LossPendingProcessing LossReason = 201 // Creative Filtered - Pending Processing by Exchange (e.g., approval, transcoding, etc.) LossDisapproved LossReason = 202 // Creative Filtered - Disapproved by Exchange LossSizeNotAllowed LossReason = 203 // Creative Filtered - Size Not Allowed LossIncorrectFormat LossReason = 204 // Creative Filtered - Incorrect Creative Format LossAdvertiserExclusions LossReason = 205 // Creative Filtered - Advertiser Exclusions LossAppStoreIDExclusions LossReason = 206 // Creative Filtered - App Store ID Exclusions (ex App Bundle Exclusions in OpenRTB <=2.5) LossNotSecure LossReason = 207 // Creative Filtered - Not Secure LossLanguageExclusions LossReason = 208 // Creative Filtered - Language Exclusions LossCategoryExclusions LossReason = 209 // Creative Filtered - Category Exclusions LossAttributeExclusions LossReason = 210 // Creative Filtered - Creative Attribute Exclusions LossAdTypeExclusions LossReason = 211 // Creative Filtered - Ad Type Exclusions LossAnimationTooLong LossReason = 212 // Creative Filtered - Animation Too Long LossNotAllowedInDeal LossReason = 213 // Creative Filtered - Not Allowed in Deal LossInvalidSKAdNetwork LossReason = 214 // Creative Filtered - Invalid SKAdNetwork LossAppBundleExclusions LossReason = 215 // Creative Filtered - App Bundle Exclusions )
LossReason options.
Values 500+ are exchange specific values; should be communicated with buyers beforehand.
type Macro ¶
type Macro struct {
// Attribute:
// key
// Type:
// string; required
// Definition:
// Name of a buyer specific macro.
Key string `json:"key"`
// Attribute:

// Definition:
// Value to substitute for each instance of the macro found in markup.
Value string `json:"value,omitempty"`
// Attribute:
// ext
// Type:
// object
// Definition:
// Optional demand source specific extensions.
Ext json.RawMessage `json:"ext,omitempty"`
}
Macro object constitutes a buyer defined key/value pair used to inject dynamic values into media markup While they apply to any media markup irrespective of how it is conveyed, the principle use case is for media that was uploaded to the exchange prior to the transaction (e.g., pre-registered for creative quality review) and referenced in bid The full form of the macro to be substituted at runtime is ${CUSTOM_KEY}, where “KEY” is the name supplied in the key attribute This ensures no conflict with standard OpenRTB macros.
type Metric ¶
type Metric struct {
// Attribute:
// type
// Type:
// string; required
// Definition:
// Type of metric being presented using exchange curated string names which should be published to bidders a priori.
Type string `json:"type"`
// Attribute:
// value
// Type:
// float; required
// Definition:
// Number representing the value of the metric.
// Probabilities must be in the range 0.0 – 1.0.
Value float64 `json:"value,omitempty"`
// Attribute:
// vendor
// Type:
// string; recommended
// Definition:
// Source of the value using exchange curated string names which should be published to bidders a priori.
// If the exchange itself is the source versus a third party, “EXCHANGE” is recommended.
Vendor string `json:"vendor,omitempty"`
// Attribute:
// ext
// Type:
// object
// Definition:
// Optional exchange-specific extensions.
Ext json.RawMessage `json:"ext,omitempty"`
}
Metric object is associated with an item as an array of metrics. These metrics can offer insight to assist with decisioning such as average recent viewability, click-through rate, etc. Each metric is identified by its type, reports the value of the metric, and optionally identifies the source or vendor measuring the value.
type NoBidReason ¶
type NoBidReason int64
NoBidReason lists the options for a bidder to signal the exchange as to why it did not offer a bid for the item.
const ( NoBidUnknownError NoBidReason = 0 // Unknown Error NoBidTechnicalError NoBidReason = 1 // Technical Error NoBidInvalidRequest NoBidReason = 2 // Invalid Request NoBidCrawler NoBidReason = 3 // Known Web Crawler NoBidNonHuman NoBidReason = 4 // Suspected Non-Human Traffic NoBidProxy NoBidReason = 5 // Cloud, Data Center, or Proxy IP NoBidUnsupportedDevice NoBidReason = 6 // Unsupported Device NoBidBlockedPublisher NoBidReason = 7 // Blocked Publisher or Site NoBidUnmatchedUser NoBidReason = 8 // Unmatched User NoBidDailyUserCap NoBidReason = 9 // Daily User Cap Met NoBidDailyDomainCap NoBidReason = 10 // Daily Domain Cap Met NoBidAuthorizationViolation NoBidReason = 12 // Ads.txt Authorization Violation NoBidAuthenticationViolation NoBidReason = 14 // Ads.cert Authentication Violation NoBidInsufficientTime NoBidReason = 15 // Insufficient Auction Time NoBidIncompleteSupplyChain NoBidReason = 16 // Incomplete SupplyChain NoBidBlockedSupplyChainNode NoBidReason = 17 // Blocked SupplyChain Node )
NoBidReason options.

func (*NoBidReason) Val ¶
func (n *NoBidReason) Val() NoBidReason
Val safely dereferences pointer, returning default value (NoBidUnknownError) for nil.
type OpenRTB ¶
type OpenRTB struct {
// Attribute:
// ver
// Type:
// string
// Definition:
// Version of the Layer-3 OpenRTB specification (e.g., "3.0").
Ver string `json:"ver,omitempty"`
// Attribute:
// domainspec
// Type:
// string; default “adcom”
// Definition:
// Identifier of the Layer-4 domain model used to define items for sale, media associated with bids, etc.
DomainSpec string `json:"domainspec,omitempty"`
// Attribute:
// domainver
// Type:
// string; required
// Definition:
// Specification version of the Layer-4 domain model referenced in the domainspec attribute.
DomainVer string `json:"domainver"`
// Attribute:
// request
// Type:
// object; required *
// Definition:
// Bid request container.
// * Required only for request payloads.
// Refer to Object: Request.
Request *Request `json:"request,omitempty"`
// Attribute:
// response
// Type:
// object; required *
// Definition:
// Bid response container.
// * Required only for response payloads.
// Refer to Object: Response.
Response *Response `json:"response,omitempty"`
}
OpenRTB top-level object is the root for both request and response payloads. It includes versioning information and references to the Layer-4 domain model on which transactions are based. By default, the domain model used by OpenRTB is the Advertising Common Object Model (AdCOM).
Some of these attributes are optional. The ver attribute, for example, indicates the OpenRTB specification version to which this payload conforms. This is also conveyed in Layer-1 via an HTTP header. Its utility here is more to assist in diagnostics by making the payload more self-documenting outside the context of a runtime transaction.
The domainver attribute, however, does have runtime utility since the structures of Layer-4 objects may vary over time based on their specification versions. This attribute can assist in invoking the correct domain object parser or unmarshalling code.
type Request ¶
type Request struct {
// Attribute:
// id
// Type:
// string; required
// Definition:
// Unique ID of the bid request; provided by the exchange.
ID string `json:"id"`
// Attribute:

// integer; default 0
// Definition:
// Indicator of test mode in which auctions are not billable, where 0 = live mode, 1 = test mode.
Test int8 `json:"test,omitempty"`
// Attribute:
// tmax
// Type:
// integer
// Definition:
// Maximum time in milliseconds the exchange allows for bids to be received including Internet latency to avoid timeout.
// This value supersedes any a priori guidance from the exchange.
// If an exchange acts as an intermediary, it should decrease the outbound tmax value from what it received to account for its latency and the additional internet hop.
TMax int64 `json:"tmax,omitempty"`
// Attribute:
// at
// Type:
// integer; default 2
// Definition:
// Auction type, where 1 = First Price, 2 = Second Price Plus.
// Values 500 and greater can be used for exchange-specific auction types.
AT AuctionType `json:"at,omitempty"`
// Attribute:
// cur
// Type:
// string array; default [“USD”]
// Definition:
// Array of accepted currencies for bids on this bid request using ISO-4217 alpha codes.

// Definition:
// Array of Item objects (at least one) that constitute the set of goods being offered for sale.
// Refer to Object: Item.
Item []Item `json:"item"`
// Attribute:
// package
// Type:
// integer
// Definition:
// Flag to indicate if the Exchange can verify that the items offered represent all of the items available in context (e.g., all impressions on a web page, all video spots such as pre/mid/post roll) to support road-blocking, where 0 = no, 1 = yes.
Package int8 `json:"package,omitempty"`
// Attribute:
// context
// Type:
// object; recommended
// Definition:
// Layer-4 domain object structure that provides context for the items being offered conforming to the specification and version referenced in openrtb.domainspec and openrtb.domainver.

// Attribute:
// ext
// Type:
// object
// Definition:
// Optional exchange-specific extensions.
Ext json.RawMessage `json:"ext,omitempty"`
}
Request object contains a globally unique bid request ID. This id attribute is required as is an Item array with at least one object (i.e., at least one item for sale). Other attributes establish rules and restrictions that apply to all items being offered. This object also interfaces to Layer-4 domain objects for context such as the user, device, site or app, etc.
type Response ¶
type Response struct {

// Type:
// string; required
// Definition:
// ID of the bid request to which this is a response; must match the request.id attribute.
ID string `json:"id,omitempty"`

BidID string `json:"bidid,omitempty"`
// Attribute:
// nbr
// Type:
// integer
// Definition:
// Reason for not bidding if applicable (see List: No-Bid Reason Codes).
// Note that while many exchanges prefer a simple HTTP 204 response to indicate a no-bid, responses indicating a reason code can be useful in debugging scenarios.
NBR NoBidReason `json:"nbr,omitempty"`
// Attribute:
// cur
// Type:
// string; default “USD”
// Definition:
// Bid currency using ISO-4217 alpha codes.
Cur string `json:"cur,omitempty"`

SeatBid []SeatBid `json:"seatbid,omitempty"`
// Attribute:
// ext
// Type:
// object
// Definition:
// Optional demand source specific extensions.
Ext json.RawMessage `json:"ext,omitempty"`
}
Response object is the bid response object under the Openrtb root. Its id attribute is a reflection of the bid request ID. The bidid attribute is an optional response tracking ID for bidders. If specified, it will be available for use in substitution macros placed in markup and notification URLs. At least one Seatbid object is required, which contains at least one Bid for an item. Other attributes are optional.
To express a “no-bid”, the most compact option is simply to return an empty response with HTTP 204. However, if the bidder wishes to convey a reason for not bidding, a Response object can be returned with just a reason code in the nbr attribute.
type SeatBid ¶
type SeatBid struct {
// Attribute:
// seat
// Type:
// string, recommended
// Definition:
// ID of the buyer seat on whose behalf this bid is made.
Seat string `json:"seat,omitempty"`
// Attribute:
// package
// Type:
// integer; default 0
// Definition:
// For offers with multiple items, this flag Indicates if the bidder is willing to accept wins on a subset of bids or requires the full group as a package, where 0 = individual wins accepted; 1 = package win or loss only.
Package int8 `json:"package,omitempty"`
// Attribute:
// bid
// Type:
// object array; required
// Definition:
// Array of 1+ Bid objects each related to an item.
// Multiple bids can relate to the same item.

Bid []Bid `json:"bid,omitempty"`
// Attribute:
// ext
// Type:
// object
// Definition:
// Optional demand source specific extensions.
Ext json.RawMessage `json:"ext,omitempty"`
}
SeatBid is an OpenRTB seatbid object. 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.
type Source ¶
type Source struct {
// Attribute:
// tid
// Type:
// string; recommended
// Definition:
// Transaction ID that must be common across all participants throughout the entire supply chain of this transaction.

// Attribute:
// ds
// Type:
// string; recommended
// Definition:
// 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.
DS string `json:"ds,omitempty"`
// Attribute:
// dsmap
// Type:
// string
// Definition:
// 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.

DSMap string `json:"dsmap,omitempty"`
// Attribute:
// cert
// Type:
// string; recommended
// Definition:
// 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.
Cert string `json:"cert,omitempty"`
// Attribute:
// digest
// Type:
// string
// Definition:
// 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.
Digest string `json:"digest,omitempty"`
// Attribute:
// pchain

// ext
// Type:
// object
// Definition:
// Optional exchange-specific extensions.
Ext json.RawMessage `json:"ext,omitempty"`
}
Source 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.
