AT Internet doesn't have a default "Push" source.
It is however possible to classify traffic from push campaigns in its own separate source.
To do so, you will need to create a new Custom marketing source in the interface:
- AS2 via Settings > Settings > Custom marketing campaigns
N.B.: your access rights must be sufficient to create or configure marketing campaigns, you can ask an admin to do this if it is not the case.
You must then create a campaign for the source and add an xtor (campaign tracker) to the link you enter in the push manager.
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).
