Hi @dgrigg,

Welcome to the Community! 

Based on what I am seeing in a previous thread here:

In order to track the ID in Google Analytics using UTM parameters, it seems like you may need to update the Profile ID variable here to 

{{ subscriber_id }}

Alternatively, I have also seen this variable referenced in API documentation as 

{{ profile_id }}

So you may also need to try with the {{ _ }} connector instead of the {{ . }}

I’d recommend trying each of the above solutions to see if you are able to successfully populate the Profile ID in your test URLs. 

Note: It may also be helpful to send yourself a test email to check the URL from your inbox instead of just checking from the Preview mode in Klaviyo.

Hope this helps!

Thanks Ashley,

It turned out this is what I needed {{ person.KlaviyoID }} That outputs the users UUID that can be used by this api end point https://developers.klaviyo.com/en/reference/get_profile to find the user. 

@dgrigg Glad you were able to find a solution!
