How can I access a web site visitor's HubSpot contact ID from my web site?

[benjaminjcharlt]

Hi!

The web site has the HubSpot tracking code embeded in every page like this:

<script type="text/javascript" id="hs-script-loader" async defer src="//js.hs-scripts.com/1234567.js"></script>

Is it possible for me, in our web site code, to retrieve the cookie that tells me the HubSpot contact ID of the current visitor?

Thank you

Benjamin

Cool!

You probably will want to reference  the get contact by user token endpoint

Going to throw a couple folks at this who will be able to give some perspective on this  --  @Kevin-C , @tjoyce any thoughts here?

Hello @benjaminjcharlt !

If you look at this doc , you will see a list of all of the possible cookies that can be set.  You are looking for the hubspotutk cookie which stores the folllowing:

• This cookie keeps track of a visitor's identity. It is passed to HubSpot on form submission and used when deduplicating contacts.
• It contains an opaque GUID to represent the current visitor.
• It expires in 13 months.

Hope this helps!

Yes, that's right, Dennis. This is exactly the document that prompted my question.

How do I get hold of this opaque GUID on the browser, and convert it into the actual integer contact ID so that I can query the HubSpot API for details about the site visitor?

Many thanks

Benjamin
