In modern customer experiences, it’s critical to unify user identities across devices and channels. This use case demonstrates how to implement identity stitching in Adobe Experience Platform (AEP) by linking a known CRM ID—captured during user login—with the anonymous Experience Cloud ID (ECID) generated by the Adobe Web SDK. By stitching these identities together in real time, AEP can build a more complete customer profile that spans both anonymous behavior and authenticated data. This enables more accurate audience segmentation, personalization, and decisioning within tools like Adobe Journey Optimizer (AJO).
