Basic question here related to Segment analytics. Unfortunately I haven't been able to find a good answer after a fair bit of searching so turning here.
I have a couple of analytics events that need to be logged against multiple users, e.g. "Matched"
Is there a way to override the "userId" property on a event without calling identify again (which would override the user for all future events & thus risks race conditions or blocking on analytics)?
This is not possible with analytics.js. If you need to send events for another userId than the one you had called .identify() with, you should use a server side library to send that event.
All server side libraries will need a userId defined so it would be a good place to send that particular event.
Also Segment just got a brand new community to post these questions fyi.
