Route server-side events to third-party analytics and ad platforms

Routing server-side events to third-party platforms produces a live, multi-destination forwarding configuration that delivers enriched, field-selected event data to analytics services, advertising platforms, and cloud infrastructure without client-side overhead. The primary outputs are the destination-specific rule actions within the forwarding property and the confirmation of received payloads at each target system (visible in GCF logs, Kinesis monitoring tabs, or S3 bucket file creation).

The key design decisions are: which fields from the edge payload are relevant to each destination (different platforms need different subsets), whether to use field-level extraction via data elements or full-payload forwarding, and how to handle authentication to each target (public endpoints, signed AWS requests, OAuth tokens). Teams should also consider the fan-out cost implications — each additional forwarding action increases edge processing latency marginally and may incur per-event billing at the destination side.

This task has medium-to-high parallelism across architectures. The AEP Event Forwarding approach is edge-native and operates in sub-100ms latency from the browser interaction. Composable equivalents use stream processors (Kafka with consumers, Kinesis Firehose, Pub/Sub subscriptions) where each consumer handles one destination. The functional result is identical — filtered event data reaching multiple third-party endpoints — but the latency, operational burden, and cost model differ significantly. Teams choosing a composable approach gain full control over field mapping and transformation logic at the cost of managing consumer infrastructure.
