The 6.3.1 release of Cequence Bridge adds Splunk HEC support as a passive, out-of-band ingestion path for API transaction telemetry. Gateway and logging sources (including IBM APIC) send events over HEC to Cequence, which validates, normalizes, and buffers them before forwarding into the Cequence UAP platform pipeline with no added latency or risk to live API traffic. The feature exposes the standard HEC event and health endpoints, handles concatenated JSON event streams with automatic timestamp normalization, and supports gzip-compressed submissions with built-in backpressure handling to protect against overload. Malformed or oversized events are isolated and rejected individually to prevent a single bad event from disrupting an entire batch or taking down the Bridge instance.
