# `OpentelemetryPlug.Propagation`
[🔗](https://github.com/bancolombia/opentelemetry_plug/blob/v1.3.1/lib/opentelemetry_plug.ex#L41)

Adds OpenTelemetry context propagation headers to the Plug response.

### WARNING

These context headers are potentially dangerous to expose to third-parties.
W3C recommends against including them except in cases where both client and
server participate in the trace.

See https://www.w3.org/TR/trace-context/#other-risks for more information.
