Summary

CloudWatch adds bearer token (API key) authentication for sending OpenTelemetry traces via the OTLP endpoint.
OTLP/HTTP clients can use an Authorization header instead of SigV4, enabling on‑premises, other cloud, CI/CD pipelines, and third‑party tool use cases.
SigV4 remains the recommended default; traces sent with either method receive the same CloudWatch capabilities.
