The trace is summarized as a tree of spans rooted at the trace root and reduced in size to keep rendering large traces in the UI practical. 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. ### Arguments #### Path Parameters | Name | Type | Description | | -------------------------- | ------ | ------------------------------------------------------------------------------------------------------------------------- | | trace_id [*required*] | string | The trace ID. Accepts either a 32-character hexadecimal string (128-bit trace ID) or a decimal string of up to 39 digits. | #### Query Strings | Name | Type | Description | | ------------------------ | ------- | ---------------------------------------------------------------------------------------------------------------------------------- | | expand_span_id | integer | Span ID to expand and preserve in the pruned tree even when its branch would normally be summarized. | | time_hint | integer | Optional Unix time hint, in seconds, used to optimize the lookup of the trace in long-term storage. | | force_source | string | Force the trace to be loaded from a specific source. When unset, the API picks the source automatically. | | include_path | array | Restrict the pruned tree to spans matching the given `key:value` pairs. Values may be passed as repeated query parameters. | | tag_include | array | Regex patterns of tag keys whose values must be included in the pruned spans. Values may be passed as repeated query parameters. | | tag_exclude | array | Regex patterns of tag keys whose values must be excluded from the pruned spans. Values may be passed as repeated query parameters. | | only_service_entry_spans | boolean | When set to `true`, only service entry spans are included in the pruned tree. | ### Response {% tab title="200" %} OK {% tab title="Model" %} Response containing a single pruned trace. | Parent field | Field | Type | Description | | -------------------- | ------------------------------------------ | --------- | ------------------------------------------------------------------------------------------------------------------------------ | | | data [*required*] | object | A pruned trace resource document. | | data | attributes [*required*] | object | The attributes of a pruned trace returned by the Get pruned trace by ID endpoint. | | attributes | is_truncated [*required*] | boolean | Indicates whether the underlying trace was truncated because its size exceeded the maximum that can be retrieved from storage. | | attributes | size_bytes [*required*] | int32 | The size, in bytes, of the original (non-pruned) trace before summarization. | | attributes | summarized_trace [*required*] | object | A summarized, hierarchical view of a trace. | | summarized_trace | root [*required*] | object | A node in the pruned trace tree. | | root | children [*required*] | [object] | The child spans of this node in the pruned tree. | | root | durationSeconds [*required*] | double | The duration of the span, in seconds. | | root | endTime [*required*] | date-time | The end time of the span, in RFC3339 format. | | root | error [*required*] | enum | Error flag for a span. `1` when the span is in error, `0` otherwise.
