disableThirdPartyCookies disablethirdpartycookies

An optional, Boolean flag that prevents the Experience Cloud Identity Service from returning the third-party, demdex.net cookie.

This configuration was idSyncDisable3rdPartySyncing and renamed to disableThirdPartyCookies in the January 18, 2018 release of v3.0.

Syntax: disableThirdPartyCookies: true|false (default is false.) For VisitorAPI.js v3.0.0 or greater.

When disableThirdPartyCookies: true, the ID service does not return the third-party, demdex.net cookie (see Cookies and the Experience Cloud Identity Service ). If a site visitor already has this cookie in their browser, the ID service won’t use it to create a new Experience Cloud ID (MID) or return an existing ID. Instead, the ID service creates a new, random MID in the first-party cookie. Once enabled, you can collect data with the ID service and share it across different Experience Cloud solutions.

Code Sample

var visitor = Visitor.getInstance ("Insert Experience Cloud organization ID here",{
   trackingServer: "Insert tracking server here here",  //Same as s.trackingServer
   trackingServerSecure: "Insert secure tracking server here",  //Same as s.trackingServerSecure

   //For CNAME support only. Exclude these variables if you're not using CNAME
   marketingCloudServer: "Insert tracking server here",
   marketingCloudServerSecure: "Insert secure tracking server here",

   //Function variable
   disableThirdPartyCookies: true
