Question

Can I update profile traits in Unify with track calls?  Can I send the traits in the context.traits object of the track call?

Product

Twilio Segment

Environment

Segment Console

Answer

No. Custom Traits are user or account traits collected from the Identify calls sent to Segment. When a Track event is dispatched with traits encapsulated within the context.traits object, these traits are intended to enrich the event data sent to a destination rather than directly update or add traits to the User Profile in Unify. 

This aligns with the designed functionality, with the primary purpose of Track events being to log user interactions with your product or website, rather than directly modifying User Profile attributes in Engage.
