Companion types value 1 means Static Resource

When to send it

Send 1 when the companion slot can display a static resource: an image file referenced by URL with its MIME type, plus a click-through link. It is the simplest companion format and the one most players can render, including audio players with a screen and many CTV apps.

Buyers with static companion banners need 1. In audio the companion image is often the only visual a campaign gets, so Audio.companiontype with 1 matters there. It is confused with 2 when an image is wrapped in HTML, which then needs an HTML-capable slot.

Example

{
  "imp": [
    {
      "audio": {
        "companiontype": [
          1
        ]
      }
    }
  ]
}
