Types

type AdInsertion

type AdInsertion int8

SSAI indicates if server-side ad insertion (e.g., stitching an ad into an audio or video stream) is in use and the impact of this on asset and tracker retrieval.

Originates from Imp.ssai property, not a separately-defined enum.

const (
	AdInsertUnknown                 AdInsertion = 0 // status unknown
	AdInsertClient                  AdInsertion = 1 // all client-side (i.e., not server-side)

}

3.2.8 Object: Audio

This object represents an audio type impression. Many of the fields are non-essential for minimally viable transactions, but are included to offer fine control when needed. Audio in OpenRTB generally assumes compliance with the DAAST standard. As such, the notion of companion ads is supported by optionally including an array of Banner objects (refer to the Banner object in Section 3.2.6) that define these companion ads.

The presence of a Audio as a subordinate of the Imp object indicates that this impression is offered as an audio type impression. At the publisher’s discretion, that same impression may also be offered as banner, video, and/or native by also including as Imp subordinates objects of those types. However, any given bid for the impression must conform to one of the offered types.

}

3.2.6 Object: Banner

This object represents the most general type of impression. Although the term “banner” may have very specific meaning in other contexts, here it can be many things including a simple static image, an expandable ad unit, or even in-banner video (refer to the Video object in Section 3.2.7 for the more generalized and full featured video ad units). An array of Banner objects can also appear within the Video to describe optional companion ads defined in the VAST specification.

The presence of a Banner as a subordinate of the Imp object indicates that this impression is offered as a banner type impression. At the publisher’s discretion, that same impression may also be offered as video, audio, and/or native by also including as Imp subordinates objects of those types. However, any given bid for the impression must conform to one of the offered types.

4.3.3 Object: Bid

A SeatBid object contains one or more Bid objects, each of which relates to a specific impression in the bid request via the impid attribute and constitutes an offer to buy that impression for a given price.

For each bid, the nurl attribute contains the win notice URL. If the bidder wins the impression, the exchange calls this notice URL to inform the bidder of the win and to convey certain information using substitution macros (see Section 4.4) such as the clearing price. The win notice return or the adm attribute can be used to serve markup (see Section 4.3). In either case, the exchange will also apply the aforementioned substitution to any macros found in the markup.

BEST PRACTICE: The essential function of the win notice is to inform a bidder that they won an auction. It does not necessarily imply ad delivery, creative viewability, or billability. Exchanges are highly encouraged to publish to their bidders their event triggers, billing policies, and any other meaning they attach to the win notice. Also, please refer to Section 7.2 for additional guidance on expirations.

BEST PRACTICE: Firing of the billing notice should be server-side and as “close” as possible to where the exchange books revenue in order to minimize discrepancies between exchange and bidder.

BEST PRACTICE: For VAST Video, the IAB prescribes that the VAST impression event is the official signal that the impression is billable. If the burl attribute is specified, it too should be fired at the same time if the exchange is adhering to this policy. However, subtle technical issues may lead to additional discrepancies and bidders are cautioned to avoid this scenario.

Several other attributes are used for ad quality checks or enforcing publisher restrictions. These include the advertiser domain via adomain, a non-cache-busted URL to an image representative of the content of the campaign via iurl, an ID of the campaign and of the creative within the campaign via cid and crid respectively, an array of creative attribute via attr, and the dimensions via h and w. If the bid pertains to a private marketplace deal, the dealid attribute is used to reference that agreement from the bid request.

3.2.18 Object: Device

This object provides information pertaining to the device through which the user is interacting. Device information includes its hardware, platform, location, and carrier data. The device can refer to a mobile handset, a desktop computer, set top box, or other digital device.

BEST PRACTICE: There are currently no prominent open source lists for device makes, models, operating systems, or carriers. Exchanges typically use commercial products or other proprietary lists for these attributes. Until suitable open standards are available, exchanges are highly encouraged to publish lists of their device make, model, operating system, and carrier values to bidders.

BEST PRACTICE: Proper device IP detection in mobile is not straightforward. Typically it involves starting at the left of the x-forwarded-for header, skipping private carrier networks (e.g., 10.x.x.x or 192.x.x.x), and possibly scanning for known carrier IP ranges. Exchanges are urged to research and implement this feature carefully when presenting device IP values to bidders.

3.2.4 Object: Imp

This object describes an ad placement or impression being auctioned. A single bid request can include multiple Imp objects, a use case for which might be an exchange that supports selling all ad positions on a given page. Each Imp object has a required ID so that bids can reference them individually.

The presence of Banner (Section 3.2.6), Video (Section 3.2.7), and/or Native (Section 3.2.9) objects subordinate to the Imp object indicates the type of impression being offered. The publisher can choose one such type which is the typical case or mix them at their discretion. However, any given bid for the impression must conform to one of the offered types.

type MarkupType

type MarkupType int8

MarkupType defines the type of the creative markup so that it can properly be associated with the right sub-object of the BidRequest.Imp.

Originates from Bid.mtype property, not a separately-defined enum.

	MarkupBanner MarkupType = 1
	MarkupVideo  MarkupType = 2
	MarkupAudio  MarkupType = 3
	MarkupNative MarkupType = 4

	Vendor string `json:"vendor,omitempty"`

	// Attribute:
	//   ext
	// Type:

}

3.2.5 Object: Metric

This object is associated with an impression as an array of metrics. These metrics can offer insight into the impression 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 Native

type Native struct {

	// Attribute:
	//   request
	// Type:
	//   string; required

	// Description:
	//   Placeholder for exchange-specific extensions to OpenRTB.
	Ext json.RawMessage `json:"ext,omitempty"`
}

3.2.9 Object: Native

This object represents a native type impression. Native ad units are intended to blend seamlessly into the surrounding content (e.g., a sponsored Twitter or Facebook post). As such, the response must be well-structured to afford the publisher fine-grained control over rendering.

The Native Subcommittee has developed a companion specification to OpenRTB called the Dynamic Native Ads API. It defines the request parameters and response markup structure of native ad units. This object provides the means of transporting request parameters as an opaque string so that the specific parameters can evolve separately under the auspices of the Dynamic Native Ads API. Similarly, the ad markup served will be structured according to that specification.

The presence of a Native as a subordinate of the Imp object indicates that this impression is offered as a native type impression. At the publisher’s discretion, that same impression may also be offered as banner, video, and/or audio by also including as Imp subordinates objects of those types. However, any given bid for the impression must conform to one of the offered types.

}

3.2.23 Object: Network

This object describes the network an ad will be displayed on. A Network is defined as the parent entity of the Channel object’s entity for the purposes of organizing Channels. Examples are companies that own and/or license a collection of content channels (Viacom, Discovery, CBS, WarnerMedia, Turner and others), or studio that creates such content and self-distributes content. Name is a human-readable field while domain and id can be used for reporting and targeting purposes. See 7.6 for further examples.

3.2.7 Object: Video

This object represents an in-stream video impression. Many of the fields are non-essential for minimally viable transactions, but are included to offer fine control when needed. Video in OpenRTB generally assumes compliance with the VAST standard. As such, the notion of companion ads is supported by optionally including an array of Banner objects (refer to the Banner object in Section 3.2.6) that define these companion ads.

The presence of a Video as a subordinate of the Imp object indicates that this impression is offered as a video type impression. At the publisher’s discretion, that same impression may also be offered as banner, audio, and/or native by also including as Imp subordinates objects of those types. However, any given bid for the impression must conform to one of the offered types.
