This article walks through implementing Adobe Marketing Cloud ID Service Append Visitor ID Function in Adobe Dynamic Tag Management (DTM)


  • Load Marketing Cloud ID Service VisitorAPI.js 1.8.0 or higher in the DTM Marketing Cloud ID Service on both the origin and target domains
  • Testing should be done in browser situations that block cookies to validate the functionality

Setup - Domain A

Set the target domain (domain B) in a sequential Top of Page Load rule with a custom third party Javascript on domain A. For example: 

Screenshot 2016-09-20 16.02.25
Screenshot 2016-09-20 16.04.57
//Code on Domain A
var domainB = "";

//Call the ID service
var visitor = Visitor.getInstance ("Insert Marketing Cloud organization ID here",{
   trackingServer: "Insert tracking server here here",  //Same as s.trackingServer
   trackingServerSecure: "Insert secure tracking server here",  //Same as s.trackingServerSecure
   //Other getInstance variables here

//Add the helper function
var domainBWithVisitorIDs = visitor.appendVisitorIDsTo(domainB);

//Redirect to Domain B
window.location = _satellite.getVisitorId().appendVisitorIDsTo(domainB)


To redirect to a more explicit path, then the domain setting needs to reflect that intention. If the redirects require a more dynamic construction, then the custom code could be added to a Data Element or Direct Call Rule. For example: var domainB = ""

Verify - Domain B

Navigate from domain A to domain B. Verify the MID on domain B matches the MID on domain a by calling the following in the developer console:
