How set google analytics client id via Tealium?

[nirb]

Hi,

I have a page which hosts an iframe to another domain. Both pages uses Tealium with Google Analytics as the tag.

I would like these 2 sessions to be the same sessions to the same user id.

I am using the linker plugin, but still need to use the same google analytics client id (cid).

I can pass the client id to the iframe using a querystring parameter, or post message event (https://developers.google.com/analytics/devguides/collection/analyticsjs/cross-domain)

How can I "tell" Tealium to use the cid and pass it to GA?

Hi @nirb,

I'm assuming that you've already setup the client ID to be shared and accessible between both domains, in that case all you need to do now is to map the client ID variable in the GUA tag and then it would use the common client ID for both domains.
