DSPBid

A single bid within a SeatBid. Each Bid relates to a specific impression in the bid request via impid and constitutes an offer to buy that impression.

idstringrequired

Bidder-generated bid ID to assist with logging and tracking.

Example: AL2PPRCAAAAAGIAAB_1_DF456GF5GD

impidstringrequired

ID of the Imp object in the related bid request.

Example: OSGMz25

admstringrequired

Ad markup for the served ad which will render on the publisher property. Format depends on the impression type.

Banner ads: a serialized JSON string. Parse before use. The parsed object contains:

Property	Type	Description
`version`	string	Native template version (e.g., `"1.0"`).
`assets`	array	Creative assets to render. See assets structure below.
`impUrls`	array[string]	Impression tracking URLs. Replace `[EVENTTIME]` with epoch milliseconds before firing.
`viewUrls`	array[string]	Viewability tracking URLs. Replace `[STARTTIME]` and `[ENDTIME]` with epoch milliseconds. `[STARTTIME]` and `[ENDTIME]` must differ by at least 1 ms.
`clickUrls`	array[string]	Click tracking URLs. Replace `[EVENTTIME]` with epoch milliseconds before firing.

All placeholder values are epoch milliseconds. See https://currentmillis.com/ for reference. Batch all tracking URLs for a given ad event in a single call where possible rather than firing them individually. For impression and engagement event tracking, see the Engagement Events API.

Assets structure (assets[]):

Property	Type	Description
`id`	integer	Unique asset identifier.
`img.url`	string	CDN URL of the creative image.
`img.width`	integer	Image width in pixels.
`img.height`	integer	Image height in pixels.
`img.type`	integer	Image layout/format type.
`native.value`	string	Custom asset value (e.g., landing page URL).
`native.type`	string	Type of the asset (e.g., `LP` for landing page).
