Field facts

Path: imp.audio.maxseq
Object: Audio
Type: integer
Requirement: Optional
Added: OpenRTB 2.4
Spec section: 3.2.8

How it is used

In 2.6 it pairs with Audio.poddur to describe a dynamic pod: the length of the break and the most spots that can fill it. Unlike the Video field of the same name, which 2.6 added and marked recommended, the Audio entry keeps its original wording and no recommendation.

Example

Where the field sits in a payload, with everything else left out:

{
  "id": "req-1",
  "imp": [
    {
      "audio": {
        "maxseq": 3
      }
    }
  ]
}

Common mistakes

Stripping it from 2.4 or 2.5 audio requests on the assumption that it is a 2.6 pod field. It is valid on Audio in both.
