How can I send the Lytics _uid (cookie ID) with event data to another 3rd party platform?

We save our unique identifiers _uid as a cookie named seerid so that can be pulled from the cookie, but we also have a built in function that works with our Javascript snippet.

You can use this to pull the _uid on any page you want:

jstag.ckieGet('seerid')

If you would like to gather this data via our APIs, check out the documentation for the personalization endpoint.
