Field facts

Path: imp.refresh.refsettings.minint
Object: RefSettings
Type: integer
Requirement: Recommended
Added: OpenRTB 2.6-202303
Spec section: 3.2.34

How it is used

The value ignores viewability and does not stop counting when the user leaves the page, so it is a floor on rendering time, not on attention.

Example

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

{
  "id": "req-1",
  "imp": [
    {
      "refresh": {
        "refsettings": [
          {
            "minint": 30
          }
        ]
      }
    }
  ]
}

Common mistakes

Sending milliseconds, such as 30000 for a 30 second interval.
