How do I tag push campaigns?

Piano Analytics doesn't have a default "Push" source. It is however possible to classify traffic from push campaigns in its own separate source.

You can rely on a “Push” custom marketing source through a tagged link with the following parameters, for example: &at_medium=Push&at_campaign=campaignPush

As with any traffic source, it will only be taken into account if the visitor isn't already on your site (if a visit is ongoing, clicking on a push notification will not change the visit's source outside of using the src_force property).
