Quantcast Measure provides free cross-platform audience measurement for your mobile app, site, network or platform.

Supported Features

  • User Analytics


In order to enable mParticle’s integration with Quantcast, you will need a Quantcast account to obtain your API Key and P-Code.

Event Data Mapping

mParticle’s integration forwards the following event types to Quantcast:

Event Type Event Mapping
App Event event=app_event, appevent={appEvent.EventName}
Application State Transition event=install, event=resume, event=load, or event=pause based on the transition type
Commerce Events event=commerce_event, app_event_name={commerceEvent.EventName}. All other event attributes passed to mParticle with the event are passed to Quantcast as attribute=value pairs.
Opt Out event=appevent, appevent=optout

Quantcast Custom Flags

You can add Custom Flags to your events, which will be mapped to Quantcast as described below.

mParticle Custom Flag Description
"Quantcast.Labels" Allows you to specify Quantcast label(s) related to an event. To leverage the hierarchical labels feature, you can set a the label in this form: <ClientID>.<Campaign ID>.<Media ID>.<User Targeting Class>, as the period indicates the different levels of the hierarchy. Any spaces in the custom flag will be replaced with the underscore ”_” character.

Reference the code samples below and the SDK docs for how to set these custom flags with the mParticle iOS and Android SDKs.

MPEvent *event = [[MPEvent alloc] initWithName:@"Set Interest"

NSArray* labels = @[ @"Example Label 1", @"Example Label 2", @"Example Label 3"];
[event addCustomFlag:[labels componentsJoinedByString:@","]

[[MParticle sharedInstance] logEvent:event];
MPEvent event = new MPEvent.Builder("Set Interest", MParticle.EventType.UserPreference)
                .addCustomFlag("Quantcast.Labels", "Example Label 1" + "," + "Example Label 2")
