Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for verifying content provided for display within a webview and interactions with such content. Methods can include providing, within a webview executing in a portion of an application launched on a client device, a first content page including a digital component and detecting, by a script executing within the webview, a set of interaction signals. After detection of the set of interaction signals, the signals can be transferred from the webview, via a communication bridge, to a software library that is resident within the native layer. The software library transmits the set of interaction signals to a first content provider, which can determine whether the interaction signals indicate interactions by an actual human user as opposed to automated interactions. The software library then launches a second content page that is linked to by the digital component.
