Field facts

Path: imp.clickbrowser
Object: Imp
Type: integer
Requirement: Optional
Added: OpenRTB 2.4
Spec section: 3.2.4

How it is used

For this flag the spec treats Safari View Controller on iOS as a native browser. Buyers care because landing pages, deep links, and attribution flows can behave differently inside an embedded web view.

Allowed values

0, 1.
