Implementing LiveRamp's Real-Time CID Delivery Tag

The Real-Time CID Delivery Tag enables you to receive a CID (your platform’s custom ID) in real time when you pass us a user’s cookie via a tag you implement on your website. This allows you to recognize a website user from anonymous site activity, and can be used for retargeting, site personalization, or measurement.

When the tag fires with the user’s cookie, LiveRamp uses the anonymized PII (personally identifiable information) we have associated with that cookie and a mapping you provide that maps your CIDs to your users’ personal information to find the CID associated with that cookie and then pass that CID back to you. All PII is anonymized during the matching process.

Real-Time CID Delivery Tags can be implemented via iframe or gif.
