getAnalyticsVisitorID

Returns the legacy Analytics ID (if any) that was stored in the s_vi cookie before the Experience Cloud Identity Service was implemented. It returns an empty string if a visitor was never assigned an Analytics ID.

Syntax var analyticsID = visitor.getAnalyticsVisitorID()

Typically, this function is used with custom solutions that require reading the visitor ID. It is not used by a standard implementation. getAnalyticsVisitorID also works with callback functions to read Analytics IDs and bring them in to your system or application.

Sample Code

//callback function 
var useAnalyticsVisitorID = function(id){ 
     //whatever your function does with the Experience Cloud ID 
}; 
 
//get Analytics ID and pass it to the function 
var analyticsID = visitor.getAnalyticsVisitorID(useAnalyticsVisitorID)
TIP

If you’re an Analytics customer, also check for and send the Analytics ID to your function. For example, you would want both identifiers when passing the visitor ID in a hidden form element to a server-side application that uses the data insertion API. In this case, you should collect and return the Experience Cloud and Analytics visitor IDs. See getMarketingCloudVisitorID.

The “aid” Parameter is a Legacy Value

The aid parameter appears in a query string under 2 different sets of conditions.

Case 1

You will see the aid parameter in a query string when:

  • The Experience Cloud ID service is deployed correctly.
  • The user visiting a site has a pre-existing Analytics ID stored in their s_vi cookie.

Case 2

You will see the aid parameter in a query string when your organization is using a grace period before fully implementing the ID service. If the user visiting your site is new, and you’re not using a grace period, the visitor will get the mid ( Experience Cloud ID) parameter.
