Targeting attributes

When you create ASRouter messages such as contextual feature recommendations or onboarding cards, you may choose to include targeting information with those messages.

Targeting information must be captured in an expression that has access to the following attributes. You may combine and compare any of these attributes as needed.

Please note that some targeting attributes require stricter controls on the telemetry than can be collected, so when in doubt, ask for review.
