2016 Release Notes release-notes

Feature releases, updates, or changes to the Experience Cloud Identity Service for 2016.

These changes are also captured in the Experience Cloud Release notes.

Version 1.10 section-7d719b3213344a46858835042e0214ed

November, 2016


Fixes and Improvements

  • Added instructions on how to implement the ID service in a server-side environment.

  • Added Visitor.overwriteCrossDomainMCIDAndAID, a boolean function that lets you overwrite the Experience Cloud and Analytics IDs on other domains that you own. See Overwrite Visitor ID.

  • Added TS = UTC timestamp as a property of the visitor.appendVisitorIDsTofunction. The ID service uses the timestamp to determine if it should use the IDs in the redirect URL based on a 5-minute aging interval. See Append Visitor ID Function.

  • Added Visitor.getLocationHint, a new function that returns a region ID. See Get Region IDs (Location Hint).

  • Added idSyncByURL and idSyncByDataSource, 2 functions that let you manually implement an ID sync in the Destination Publishing iFrame. See ID Synchronization by URL or Data Source.

  • Fixed a bug that blocked the AppMeasurement tracking call if disableThirdPartyCalls:true.

  • Fixed a bug that prevented the ID service from passing the Experience Cloud ID (MID) across different domains.

Version 1.9.0 section-04e1b4d4b10d40468f2116b8119998e7

October, 2016

Fixes and Improvements

  • Fixed a bug that passed Audience Manager unique user IDs (AAMUUIDs) as Experience Cloud IDs to the ID service.
  • If time-to-live (TTL) for an AMCV cookie has expired, the ID service will still return that information to the server as long as the cookie contains a Experience Cloud ID. After this call, the ID service makes an asynchronous call to update the cookie. This helps improve performance because the ID service doesn’t have to wait for a server response. It can use existing AMCV cookie values and then request an update.
  • The ID service automatically synchronizes Experience Cloud IDs (MIDs) with Adobe Media Optimizer and other internal Adobe domains directly on the page. Automatic synchronization is enabled for all existing and new accounts. This helps improve match rates for Media Optimizer. Applies to VisitorAPI.js version 1.8, or higher. See also, Understanding ID Synchronization and Match Rates.

New and Revised Documentation

New: Get Region and User IDs From the AMCV Cookie

Version 1.8.0 section-69f2eb5b246b4c7aafe116b7a2a5448a

September, 2016

Fixes and Improvements

Added disableThirdPartyCalls as an optional, Boolean flag you can set in the Visitor.getInstance function. When disableThirdPartyCalls= true, the ID service will not make calls to other domains. By default, disableThirdPartyCalls= false. See disableThirdPartyCalls.

Version 1.7.0 section-f7d59104de6644fca3691480383d4644

August, 2016

Fixes and Improvements

  • Added idSyncAttachIframeOnWindowLoad as an optional boolean flag you can set in the Visitor.getInstance function. When idSyncAttachIframeOnWindowLoad= true, the ID service loads the ID synchronization iFrame on window load. By default, the ID service loads the iFrame as fast as possible. This flag replaces idSyncAttachIframeASAP, which is deprecated. See Visitor.getInstance Function Variables.

  • Added functionality to support tracking Experience Cloud IDs across domains, native apps and hybrid apps to web transitions. See Append Visitor ID Helper Function.

  • Added functions to visitorAPI.js code that determine if the ID service has generated the visitor Experience Cloud ID client-side or server-side or if ID calls timed out. See Timeout Tracking Functions and Tracking Client-side Visitor ID Generation.

New and Revised Documentation

Revised: Requirements for the Experience Cloud Identity Service

Known Issues

Customers using Audience Manager DIL code and visitorAPI.js code on the same page should set the DIL variable secureDataCollection= false. See secureDataCollection.

Version 1.6.0 section-3faaa14bf3934c6a99b8f79ee06fc0d2

July, 2016

Version 1.6.0 of the Experience Cloud ID service requires AppMeasurement for JavaScript version 1.6.2. If you upgrade to ID service version 1.6.0, please make sure you are using the right AppMeasurement code version.
Cross-Origin Resource Sharing (CORS)

CORS allows browsers to request resources from a domain other than the current domain. The Experience Cloud Identity Service supports CORS standards to enable client side, cross-origin resource requests. The ID service reverts to JSONP requests on browsers that do not support CORS.


Fixes and Improvements

  • Added a d_fieldgroup parameter to ID synchronization calls to dpm.demdex.net. This new parameter is used for internal troubleshooting and debugging purposes.

  • Added a title attribute to the ID service iFrame. An iFrame title helps screen readers provide page information to users who require assistance when interacting with online content. The iFrame title attribute is set to Adobe ID Syncing iFrame.

  • Added idSyncAttachIframeASAP: true as an optional flag you can set in the Visitor.getInstance function. When true, the ID service loads the ID synchronization iFrame as fast as possible. This is designed to help improve ID synchronization match rates. By default, the ID service loads the iFrame on window load. See Visitor.getInstance Function Variables.

  • Fixed a bug with a callback function that caused AppMeasurement to get stuck in an infinite loop.

  • Changed the default loadTimeout interval to 30,000 milliseconds (from 500 milliseconds). See Visitor.getInstance Function Variables.

New and Revised Documentation



Version 1.5.7 section-735b4989a5744a42aeb2d97602dbda62

June, 2016

Changes to the iframe.sandbox attribute

The iFrame is now set so that iframe.sandbox='allow-scripts allow-same-origin'; .

Allowing only these 2 tokens helps improve security and provides the ID service with the basic functionality required for ID synchronization.

The sandbox attribute is not supported in Internet Explorer version 9 or earlier. For more information, see the Attributes section in this iFrame documentation.

Encoding the Experience Cloud ID (MID)
The ID service encodes the MID value returned from the server or when it's set by the visitor.setMarketingCloudVisitorID() function. For more information about the MID, see Cookies and the Experience Cloud ID.


The visitor API no longer forces an extra re-synchronization call with Audience Manager when there is no legacy Analytics visitor ID.

Version 1.5.x section-a62ae48275324058b57edf66ee5a579f

Opt-out support
The Experience Cloud ID service supports visitor opt-out requests.
Change ID synchronization interval
The Experience Cloud ID service now makes ID synchronization calls on every call to the data collection servers. Previously, the ID service made only 1 request on the first call to get a Experience Cloud ID.
