Field facts

Path: imp.audio.delivery
Object: Audio
Type: integer array
Requirement: Optional
Added: OpenRTB 2.4
Values: AdCOM list Delivery Methods
Spec section: 3.2.8

How it is used

Match it to how the ad's media file is fetched. When the ad is stitched into the content server-side, the stitcher fetches the file, so list what the stitcher accepts.

Allowed values

Value	Meaning
`1`	Streaming: The ad's media is delivered by a streaming protocol rather than as a single file.
`2`	Progressive: A single media file downloaded over HTTP and played while it downloads.
`3`	Download: The media file is fully downloaded before playback starts. Added in OpenRTB 2.4.

Example

  "id": "req-1",
  "imp": [
    {
      "audio": {
        "delivery": [
          1
        ]
      }
    }
  ]
}

Common mistakes

Sending strings such as "streaming" instead of the integer codes.
