Buyer SDK ad format
Stay organized with collections Save and categorize content based on your preferences.

Buyer SDK ads use creatives rendered by your own SDK.

Mobile app inventory from publishers who integrate your bidding adapter into their app can accept bids with the buyer SDK rendered ad format. How they render is based on your SDK implementation and the SDKRenderedAd you submit in the bid response.

You can place a bid including either a buyer SDK rendered ad or any other ad format supported by the Google Mobile Ads SDK, but any bids containing both are filtered.

Requirements

Buyer SDK ads are available to approved buyers. This format requires extra effort from you and the publisher. Contact your Technical Account Manager to configure your account for buyer SDK ads. You can then implement a Bidding adapter that enables your SDK to communicate with the Google Mobile Ads SDK. The publisher needs to integrate your SDK and adapter into their mobile apps.

We recommend you submit creatives for review before including them in a bid response. Contact your Technical Account Manager if you don't know the creative type at bid time.

If a bid request supports this ad format, you can specify an ad that renders with your SDK by setting the sdk_rendered_ad field in the bid response.

Bid request

Bid requests for mobile app inventory include details about the SDKs and adapters in the publisher's app that you can use for rendering in the following fields:

SDK ID: You can use the bid request to find the SDK ID that you must provide in the bid response with the BidRequest.app.ext.installed_sdk.id field.; You can learn more about this in the InstalledSdk reference documentation.
Ad Unit Mapping: You can use the bid request to find the ad unit mappings that match the bid slot with the BidRequest.imp.ext.ad_unit_mapping field.; You can learn more about this in the AdUnitMapping reference documentation.
Secure Signals: Publishers can share secure signals with bidders. You can find these in BidRequest.imp.ext.buyer_generated_request_data.data.; You can learn more about how secure signals are represented in the BuyerGeneratedRequestData reference documentation.
Test Requests: You can use the BidRequest.test field to verify whether the bid request is a test.; You can learn more about the this field in the BidRequest reference documentation.

Bid response

The following fields are required in the bid response:

BidResponse.seatbid.bid.adomain
BidResponse.seatbid.bid.ext.billing_id
BidResponse.seatbid.bid.crid
BidResponse.seatbid.bid.w
BidResponse.seatbid.bid.h

Additionally, your bid response must populate BidResponse.seatbid.bid.ext.sdk_rendered_ad with the following:

SDK ID

Use the id field to provide the ID for the SDK to render the ad.

You can find the ID in BidRequest.app.ext.installed_sdk.

Declared ad

Use BidResponse.seatbid.bid.ext.sdk_rendered_ad.declared_ad to provide a creative that meets the requirements found in BidRequest.imp.ext.creative_enforcement_settings and is representative of the ad's rendering data. Only one of html_snippet, video_url, video_vast_xml, or native_response should be populated.

If you don't populate declared_ad, we're unable to review the creative and all bids with the creative are filtered from the auction.

You can learn more about the declared ad in the DeclaredAd reference documentation.

Rendering data

Use the BidResponse.seatbid.bid.ext.sdk_rendered_ad.rendering_data field to provide the data for the buyer SDK to use to render your ad.

Bids to place a buyer SDK ad must specify a creative in the declared_ad field. The declared ad must accurately represent the rendering_data.

Here's a sample SdkRenderedAd object:

{
  "id": "1234567",
  "rendering_data": "\xd58...,\xd4\x89\xd\xf9",
  "declared_ad": {
    "html_snippet": "<iframe src=\"https://example.com/ads?id=123&
      curl=%%CLICK_URL_ESC%%&wprice=%%WINNING_PRICE_ESC%%\"></iframe>",
  }
}

We recommend using the Real-time Bidding API to submit creatives for review before you include them in a bid response.

See the OpenRTB guide for more details on the SdkRenderedAd fields.

Creative review

Creatives are reviewed before they can serve to ensure they meet our policies and publisher settings.

Here are two ways you can submit creatives for review:

Real-time Bidding API (recommended)

You can use the buyers.creatives.create method of the Real-time Bidding API to submit creatives for review.

The API requires only one submission per creative and lets you check the status of your creative's review.

Bid response

You can submit new creatives directly in the bid response.

You must use the declared_ad field of the SdkRenderedAd object to submit a bid response with a buyer SDK creative for review.

Creatives submitted in the bid response are only reviewed after many bids. All bids placed before the review is complete are filtered from the auction. You can use the Real-time Bidding interface or Real-time Bidding API to check the status of a creative after the review starts.

See the creatives guide for more details.
