BidRequest

Google RTB	OpenRTB	Notes
id	BidRequest.id	The Google RTB id has type bytes, while the OpenRTB id is a base64-encoded string.
ip	BidRequest.device.ip BidRequest.device.ipv6	Nearly equivalent. The Google RTB ip is represented as a bytes binary in network byte order, while OpenRTB's ip and ipv6 are a string representation of the IP address. For example, in Google protocol ip could be set to \x7f\x00\x00, and the equivalent value of ip for OpenRTB would be "127.0.0.0". The mapped field is dependent on whether the IP is an IPv4 or IPv6 address.

Video

Parent: BidRequest

Google RTB	OpenRTB	Notes
placement	BidRequest.imp.video.placement	Nearly equivalent. The Google RTB protocol and OpenRTB use different enum values, which have the following mapping: INSTREAM = 1 → IN_STREAM_PLACEMENT = 1 INTERSTITIAL = 2 → FLOATING_PLACEMENT = 5 IN_FEED = 3 → IN_FEED_PLACEMENT = 4 IN_ARTICLE = 5 → IN_ARTICLE_PLACEMENT = 3 In cases where Google RTB protocol doesn't populate placement, OpenRTB will set it to IN_BANNER_PLACEMENT. This is deprecated. We recommend that you use BidRequest.imp.video.plcmt instead.

max_ad_duration	Non-native video: BidRequest.imp.{video/audio}.maxduration Native video: BidRequest.imp.native.{request/request_native}.assets.video.maxduration See native ad migration notes for more details on differences between JSON and Protobuf formats.	Nearly equivalent. The Google RTB protocol uses a single field for both native and non-native video, and represents this in milliseconds, whereas OpenRTB differentiates between native and non-native video by using different field paths, and uses seconds.
min_ad_duration	Non-native video: BidRequest.imp.{video/audio}.minduration Native video: BidRequest.imp.native.{request/request_native}.assets.video.minduration See native ad migration notes for more details on differences between JSON and Protobuf formats.

max_ads_in_pod	BidRequest.imp.video.maxseq	Equivalent.
max_pod_duration_seconds	BidRequest.imp.video.poddur	Equivalent.
video_ad_skippable	BidRequest.imp.video.skip	Nearly equivalent. OpenRTB's field is less granular because it is represented as a boolean. Both of Google RTB protocol's ALLOW_SKIPPABLE and REQUIRE_SKIPPABLE enum names would result in the OpenRTB field being set to True. We recommend contacting your TAM to enable skip correction.
skippable_max_ad_duration	BidRequest.imp.{video/audio}.maxduration	Non-trivial updates required. The Google RTB protocol represents this in milliseconds, whereas the OpenRTB protocol uses seconds. OpenRTB doesn't support display of both maximum duration for skippable and non-skippable ads simultaneously. Google uses bid flattening to represent both cases. For more details, see our documentation on maximum skippable video duration.
protocols	Non-native video: BidRequest.imp.{video/audio}.protocols Native video: BidRequest.imp.native.{request/request_native}.assets.video.protocols See native ad migration notes for more details on differences between JSON and Protobuf formats.	Nearly equivalent. The Google RTB protocol uses a single field for both native and non-native video, whereas OpenRTB differentiates between native and non-native video. Google RTB protocol enum names and values are equivalent in OpenRTB, but additional (currently unused) enum names exist in OpenRTB.
allowed_video_formats	Non-native video: BidRequest.imp.{video/audio}.mimes Native video: BidRequest.imp.native.{request/request_native}.assets.video.mimes See native ad migration notes for more details on differences between JSON and Protobuf formats.

content_attributes.duration_seconds	BidRequest.{site/app}.content.len	Equivalent.
is_livestream	BidRequest.{site/app}.content.livestream	Equivalent.
playback_cessation_mode	BidRequest.imp.video.playbackend	Equivalent.

CompanionSlot

Parent: Video

Google RTB	OpenRTB	Notes
height	BidRequest.imp.{video/audio}.companionad.h BidRequest.imp.{video/audio}.companionad.format.h	Nearly equivalent. The Google RTB protocol uses separate repeated integer fields to represent width and height, where a given index in both describes a supported size. We recommend using OpenRTB's companionad.format, which is a repeated field of type Format that can represent multiple sizes. Note that companionad.{h/w} can only represent one size.
width	BidRequest.imp.{video/audio}.companionad.w BidRequest.imp.{video/audio}.companionad.format.w	Nearly equivalent. The Google RTB protocol uses separate repeated integer fields to represent width and height, where a given index in both describes a supported size. We recommend using OpenRTB's companionad.format, which is a repeated field of type Format that can represent multiple sizes. Note that companionad.{h/w} can only represent one size.
creative_format	BidRequest.imp.{video/audio}.companiontype BidRequest.imp.{video/audio}.companionad.mimes	Nearly equivalent. Google RTB protocol uses different enum names and values than OpenRTB. IMAGE_CREATIVE = 0 → STATIC = 1 FLASH_CREATIVE = 1 → N/A (Flash is no longer supported.) HTML_CREATIVE = 2 → HTML = 2 These are also reflected in OpenRTB's mimes field for the companion ad. Unlike Google RTB protocol, OpenRTB supports an additional type: COMPANION_IFRAME.

The representation across the Google RTB protocol and OpenRTB are identical, however the OpenRTB field used differs based on the ad format. When there are multiple eligible banner sizes, Google RTB protocol represents dimensions with width/height pairs at the same index, whereas OpenRTB uses the repeated format field. Unlike the banner format, when there are multiple eligible video sizes, only the width of the first will be provided in BidRequest.imp.video.w.
height	BidRequest.imp.banner.h BidRequest.imp.banner.format.h BidRequest.imp.native.{request/request_native}.assets.video.h BidRequest.imp.video.h	Nearly equivalent. The representation across the Google RTB protocol and OpenRTB are identical, however the OpenRTB field used differs based on the ad format.

slot_visibility	BidRequest.imp.banner.pos BidRequest.imp.video.pos	Nearly equivalent for banner and video ads. OpenRTB's pos field also maps to Google RTB protocol's StickySettings. Enum names relevant to slot_visibility are ABOVE_THE_FOLD and BELOW_THE_FOLD, which have different integer values in OpenRTB (1 and 3 respectively). Note that visibility is not a factor for audio ads, which are represented separately from video ads in OpenRTB. Unsupported for native ads.
viewability	BidRequest.imp.metric.value	Nearly equivalent. The Google RTB protocol represents this as an integer percentage ranging from 0-100, whereas OpenRTB represents this as a double ranging from 0.0-1.0.
