Native Display

The request.item.spec.placement.display.nativefmt object defines a display placement to be specifically a native display placement. It serves as the root of a structure that includes the specifications for each of the assets that comprise the native placement.

Native Request Object
Value Type Description
asset array of objects An array of Asset Objects which specify the set of native assets and their permitted formats, see Native Asset Object

Native Asset Object

Native Asset Object Properties
Value Type Description
id integer (Required) Unique asset ID, for example 2
req integer Set to 1 if the asset is required, i.e. the exchange will not accept a bid without it, the default is 0.
title* object (Required) Native title object, see the Native Asset Title Object for more details.
img* object (Required) Native image object, see the Native Asset Image Object for more details.
video* object (Required) Native video object, see the Native Asset Video Object for more details.
data* object (Required) Native asset data object, see the Native Asset Data Object section for more details.

Note

(*) Exactly one of the fields marked with an asterisk is required in the asset object.

Native Asset Title Object

Native Asset Title Object
Value Type Description
len integer Maximum length of the text in the title element, for example, 25. Recommended lengths in the IAB Open RTB spec are 25, 90, or 140.

Native Asset Image Object

The image asset object may contain the exact image size, the minimum image size, or both. If only the exact image size is specified then the image in the bid response should have the corresponding size. If the minimum size is specified then the image asset in the bid response should comply with the following restrictions.

  • The size of the image should be equal to or larger than the minimum specified
  • The image asset in the bid response should contain the w and h fields.

Note

It is recommended that the aspect ratio of the image should be close to the one specified by the exact size or by the minimum size; the acceptable aspect ratio deviation is from \(0.8 * (w/h)\) to \(1.25 * (w/h)\)

    • Small: It must have a maximum height of at least 200 DIPS; and a maximum width at least 200, 267, or 382 DIPS (i.e., aspect ratios of 1:1, 4:3, or 1.91:1, respectively).

  • -1: Generic mid-roll
  • -2: Generic post-roll
