### Overview

Retrieve a full APM trace by its trace ID, including every span in the trace. Traces are returned from live storage when available and fall back to longer-term storage. This endpoint is rate limited to `60` requests per minute per organization. This endpoint requires the `apm_read` permission.

OAuth apps require the `apm_read` authorization [scope](https://docs.datadoghq.com/api/latest/scopes.md#apm-trace) to access this endpoint.
