Announcement: Enable Online Identifier-Based Measurement with the Enhanced Client-Side Tag (9/24/21)
Customers now have the chance to capture additional online identifiers (beyond cookies) with the Enhanced Client-Side Tag (eCST), which is now in open beta for measurement use cases. In addition to the capabilities of the standard Client-Side Tag (CST), the eCST can also be placed in mobile web applications, in-app mobile, or CTV environments to capture their corresponding device identifier.
In addition to the cookies that are captured automatically, the eCST can collect the following identifier types:
Mobile device IDs (IDFAs and AAIDs)
Over The Top (OTT) and Connected TV (CTV) IDs
Identity Envelopes (that contain RampIDs)
The eCST can also track authentications on websites or mobile web apps by capturing Identity Envelopes generated using LiveRamp’s Authenticated Traffic Solution (ATS).
This eCST open beta will be strictly for U.S. data and measurement (Measurement Enablement) use cases, where the data captured is returned to you (or a partner) in log files that include the corresponding RampID(s) for the identifier captured.
Note
Stay tuned for more information on an upcoming open beta for eCST for activation use cases, where we create segments in your Connect account, which you can then distribute to your desired destinations.
For more information on the eCST (and the CST), see “LiveRamp's Client-Side Tags”.
