# Otel Traces

`POST /internal/otel/v1/traces`

Forward an OTLP /v1/traces batch to Langfuse with auth swap.

Returns 202 immediately and forwards to Langfuse as a background task.
Starlette runs background tasks only after the response is flushed, so the
worker's OTLP exporter receives the 202 without blocking on the ~10s
Langfuse round-trip. Langfuse errors are swallowed and reported to Sentry
so a downstream outage never breaks worker runs (fire-and-forget tracing).

## Response `202`

Successful Response
