getInstance getinstance

getInstance returns a visitor ID object for the specified Experience Cloud organization ID. This is required to initialize the visitor ID object provided to AppMeasurement through s.visitor.

Syntax

JavaScript

var visitor = Visitor.getInstance("INSERT-MARKETING-CLOUD-ORGANIZATION-ID-HERE", {
     trackingServer: "INSERT-TRACKING-SERVER-HERE", // same as s.trackingServer
     trackingServerSecure: "INSERT-SECURE-TRACKING-SERVER-HERE", // same as s.trackingServerSecure

     // To enable CNAME support, add the following configuration variables
     // If you are not using CNAME, DO NOT include these variables
     marketingCloudServer: "INSERT-TRACKING-SERVER-HERE",
     marketingCloudServerSecure: "INSERT-SECURE-TRACKING-SERVER-HERE" // same as s.trackingServerSecure
});
CAUTION
Do not instantiate the Visitor function with var visitor = new Visitor. You must use the proper function call noted here. Applies to VisitorAPI.js code library v3.0 or higher.

ActionScript / Flash

import com.adobe.mc.Visitor;
...
var visitor = Visitor.getInstance("INSERT-MARKETING-CLOUD-ORGANIZATION-ID-HERE", {
     trackingServer: "INSERT-TRACKING-SERVER-HERE", // same as s.trackingServer
     trackingServerSecure: "INSERT-SECURE-TRACKING-SERVER-HERE", // same as s.trackingServerSecure

     // To enable CNAME support, add the following configuration variables
     // If you are not using CNAME, DO NOT include these variables
     marketingCloudServer: "INSERT-TRACKING-SERVER-HERE",
     marketingCloudServerSecure: "INSERT-SECURE-TRACKING-SERVER-HERE" // same as s.trackingServerSecure
});

If getInstance doesn’t find an existing instance, an new instance is created and returned. This is similar to the s_gi() functionin AppMeasurement.

Common Use

The Experience Cloud ID service API maintains a list of all instances created for each Adobe Experience Cloud organization ID. If the application using the ID service API isn’t passing around a reference to the instance, it can find that instance by calling getInstance instead of creating a new one. This also provides support for multiple instances for different organizations in the same web page or application.

This is useful for applications that don’t have a clear init phase, but need to call into the ID service API in multiple places. You can call getInstance in all of those places and the first to execute will create the instance. The existing instance will be returned by subsequent calls.
