DV360 OpenRTB Specification

Key Point: Ensure bid requests comply with the DV360 OpenRTB specification.

Display and Video 360 supports the following OpenRTB versions:

• 2.3.x
• 2.4
• 2.5

Ensure you have the OpenRTB 2.5 Specification Guide available while consulting this page.

Display and Video 360 does not support all fields in the OpenRTB specification, and several nuances may apply. Sections of this document contain information and recommendations specific to the Display and Video 360 implementation. You should also follow the guidelines presented in the OpenRTB specification unless instructed otherwise.

Supported Extension for Source object

This extension is highly recommended since it will impact how viewability measurements are reported in DV3 to the customer. If the OMID partner name is NOT on the IAB certification list, we are required by MRC to report the viewability metrics separately from the MRC certified metrics. Learn more.

Supported extension for Device object

If ip is changed or truncated, we strongly recommend sending the below extensions to prevent traffic being declared as invalid traffic.

Attribute	Implementation details
truncated_ip	Indicate whether the ip address in the device.ip field of the bid request is truncated. 1= truncated 0= not truncated. It is assumed not truncated and required if the ip address is truncated. If not declared the bid request might be classified as invalid traffic.
ip_less	Indicate whether device.ip field contains the actual client ip. 1 = device.ip does not include the actual client ip 0 = device.ip does contain the actual client ip. The assumed value is 0 which indicates that the client ip address is present. In cases of ip_less = 1 traffic, the forwarding server ip should be included in the device.ip field.
ifa_type	Indicate the origin of the device.ifa field, whether it was provided from the device itself or generated by publisher or SSP in the supply chain. Supported values in the table below.

ifa_type	Device Platform
"aaid"	Android TV
"rida"	Roku

Ad serve options

In section 4.3 of the OpenRTB specification there are two different serving options:

• Markup served on the win notice
• Markup served in the bid

DV360 supports both options.

• For Banner ad, DV360 always returns markup in the adm field. Markup served on win notice is optional.
• For Video/Audio ad using VAST protocol, DV360 supports returning VAST XML in the adm field or in the response of win notice based on requirements from exchange partners.

Refer to the OpenRTB specification to know the pros and cons of these two options.

Best practices

It is highly recommended to use the Partner ID of Display and Video 360 as the seat ID. The use of exchange-specific seat ID is not recommended.

Ensure your publishers have ads.txt files, or applications with app-ads.txt files associated, and they list you in the file as an authorized seller or reseller. Learn more.

Also ensure consistent information is passed in bid requests. For example, the app.bundle must be consistent with the mobile device information and app.storeurl.

Connected TV

Adhere to the IAB OTT IFA guidelines in passing device.ifa and device.lmt. You should also implement device.ext.ifa_type to be compliant with the guidelines. All of our CTV frequency capping and audience targeting capabilities will require the presence of an IFA.

Also adhere to the recently published IAB OTT/CTV Store Assigned ID guidelines—this defines how app.bundle should be passed for CTV apps—largely using the app store defined ID.

Active View Measurement

Active View is a Google technology used to measure if an impression was viewable and for how long. Active View uses OMID for both display and video ads. To enable measurement using OMID, exchanges must add the following fields in OpenRTB requests so that DV360 knows the client's support of OMID.

• Required: Add an API Framework (Video.api=7 for OMSDK) to bid requests. This is mandatory for Active View to enable measurement using OMID.
• Recommended: Adding omidpn and omidpv to Source.Ext is highly recommended because it will impact how viewability measurements are reported in DV360 to the customer. If the OMID partner name is NOT on IAB certification list, we are required by MRC to report the viewability metrics separately from the MRC certified metrics. Learn more.

FAQ

Does DV360 Support exchange custom extensions?

Yes, in addition to the extensions listed in this specification, Display and Video 360 may also support custom extensions on a case-by-case basis. It is recommended to specify and test the custom extension during the integration period. Does DV360 support rewarded Video?

Yes, send us the rewarded Video extension.

A lot of my inventory is showing up as demographics unknown, how do I improve demographic coverage?

Populate user.yob and user.gender in bid requests to DV360 to increase coverage.

Does DV360 have endpoints for each region?

No, we use a single endpoint globally and we automatically route requests to the nearest data center, so there's no region-specific endpoint we can provide.

What are the requirements for server-to-server (s2s) requests?

The Serverside extension signal is required to better classify server-to-server traffic. If the VAST fetch comes from a server, reach out to request addition to our allowlist. The client User Agent has to be forwarded, and ensure that cookies are disabled/ignored in the response to an s2s VAST fetch.

Does DV360 support OMID?

We are able to measure viewability using OMID as long as it is declared as OMID-enabled at bid request time. Details about this are summarized on pages 24-25 here.

Which version of Native do you support? Do you have any Native requirements?

We only support Native Ver1.2. Native specification here.

Does DV360 support SSP click tracking macros?

DV360 does support SSP click tracking for display creatives. It needs to be set up on our side to ensure that nothing breaks with our existing click tracking setup so please reach out to request this.

Does DV360 support bid requests sent as GZIP?

DV360 can receive gzip compressed bid requests, and will respond with gzip compressed responses if Accept-Encoding header indicates it's supported.

Does DV360 support DBURL?

Not at the moment.

Does DV360 support win loss notification?

Not at the moment. If you think it would be useful for us to support it please reach out with more details.

Does DV360 require App.name for targeting?

No, DV360 using App.name for reference but it is not required for targeting, App.bundle is used for targeting.

Can DV360 support multiple ad sizes sent in a single bid request?

Yes we can, but it requires a configuration change. Reach out to request this.

Does DV360 support multiple formats in the same bid request?

We have limited support for multi-format bid requests, but are working on improving. We support display & video formats for interstitials, but do not currently support display & native. If you are sending multi-format bid requests, please reach out to request a test.

Does DV360 support mixed impression types in the same request?

Currently we only support video/banner interstitials. We are working on native/banner & video/banner. If there are other combinations please reach out to our team and let us know.

Can multiple seats each send multiple bids on one or more of such impression opportunities in the same request?

Yes.

Does DV360 have a solution or particular need regarding capping or displaying the same advertiser for multiple such impression opportunities in the same request?

DV360 places enforcement that one advertiser can only bid up to one imp opportunities for each request. We expect SSPs to group imp objects meaningfully—e.g., all on the same page, all in the same app, etc.

Does DV360 support multiple impressions in the same bid request?

DV360 currently supports video, unlimited, with any combinations of imp objects being the same or not. However, we will need to test/enable each exchange on this. We are working on expanding this to other formats:
