CurrentintegerOptionalSince 2.0

Field facts

Path: app.content.len, dooh.content.len, site.content.len
Object: Content
Type: integer
Requirement: Optional
Added: OpenRTB 2.0
Spec section: 3.2.16

How it is used

On long-form video it helps buyers tell clips from full episodes and films. For a live stream with no fixed length, leave it out rather than sending 0.

Example

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

{
  "id": "req-1",
  "app": {
    "content": {
      "len": 2700
    }
  }
}

Common mistakes

Sending milliseconds. A 45 minute episode is 2700, not 2700000.
