Cookie “_mkto_trk” has been rejected for invalid domain using Marketo Munchkin Extension in Adobe Experience Manager Site.

We’re facing the problem of Munchkin cookie being rejected due to invalid domain on our AEM site, and we’re wondering if anyone can advise or give us some hints?

—----------

Expected Result: Initial Munchkin cookie in our AEM site (publish-xxxxxx.adobeaemcloud.com) via Adobe Data Collection (the tag manager on Adobe Experience Platform)

 

Our Steps: 

  1. Set Tag Property as “adobeaemcloud.com” in Adobe Experience Platform > Data Collection. 
  2. Install Marketo Munchkin Extension on Adobe Experience Platform, add Munchkin.ini rule
  3. Add data collection script in AEM. 
  4. Load the page (publish-xxxxxx.adobeaemcloud.com)
  5. Munchkin.js is successfully launched, but Cookie “_mkto_trk” has been rejected for invalid domain.

 

What We’ve tried: 

  1. Set the domainLevel to 2 in Marketo Munchkin Extension, but it won’t build in Adobe Experience Platform. 
  2. Replace the js in head using Adobe Debugger using initMunchkin() script.

Appreciate anyone can give us some hints.

You can’t set cookies at the domain adobeaemcloud.com because that’s considered a public domain suffix, i.e. listed on the PSL.

 

Public domain suffixes are like implicit or effective TLDs. They’re technically private in the sense that they’re controlled by a private entity. But they’re shared by multiple tenants of that entity, so it wouldn’t be safe to have one tenant read another tenant’s cookies.  As a result you’re only allowed to set cookies at your specific subdomain, publish-p56999-e462086.adobeaemcloud.com. Note this is a browser restriction, not related to Marketo or Munchkin.

Hello Sanford,

Here's our test link and appreciate any advise:
https://publish-p56999-e462086.adobeaemcloud.com/content/cmc/us/en/mkto-test.html

(we've tried the code on local host and it worked. However we can't make it work when we publish it to Adobe Experience Cloud)

 

Thank you.
