Field facts

Path: imp.qty.multiplier
Object: Qty
Type: float
Requirement: Required
Added: OpenRTB 2.6-202211
Spec section: 3.2.31

How it is used

A 10.00 CPM bid on a play with a multiplier of 42 costs 0.42 for that play. The field corresponds to qtyflt in OpenRTB 3.0.

Example

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

{
  "id": "req-1",
  "imp": [
    {
      "qty": {
        "multiplier": 14.2
      }
    }
  ]
}

Common mistakes

Omitting it. A Qty without a multiplier is missing its only required field, and the validator reports openrtb.field.required.
Sending the number as a string such as "42", a type mismatch for a float field.
