LiveRamp's IDL Mapper Sidecar

The LiveRamp IDL Mapper Sidecar (or “sidecar”) enables IdentityLinks (IDLs) and other people-based IDs in real-time bidding (RTB) bid requests for Supply-Side Platforms (SSPs). The sidecar allows an SSP to decode the Identity Envelopes LiveRamp has provided them into Demand-Side Platform-specific IdentityLinks and other people-based identifiers that can be utilized for identification purposes of the underlying browser in RTB bid requests. No communication with LiveRamp is required at impression time, enabling low-latency usage of the sidecar.
