Tencent APM, also known as TAPM, is a monitoring and observability platform that provides a comprehensive view of your application’s performance and behavior. Tencent APM natively supports OpenTelemetry, so you can use OpenLLMetry to trace your applications.
To integrate OpenLLMetry with Tencent APM, you’ll need to configure your tracing endpoint and authentication: 
TRACELOOP_BASE_URL="<TAPM_ENDPOINT>" # Use port `55681` rather than `4317` as the default port.
TRACELOOP_HEADERS="Authorization=Bearer%20<TAPM_TOKEN>" # header values in env variables must be URL‑encoded.
Tencent APM defaults to using port 4317 for the gRPC exporter, and we recommend using port 55681 instead here, which is the HTTP exporter port.
