# Create dataset items from traces

POST http://localhost:5173/api/v1/private/datasets/{dataset_id}/items/from-traces
Content-Type: application/json

Create dataset items from traces with enriched metadata

Reference: https://www.comet.com/docs/opik/reference/rest-api/datasets/create-dataset-items-from-traces

## Servers

- `http://localhost:5173/api` (Local server, default)
- `https://www.comet.com/opik/api` (Opik Cloud)

## Request

### Path parameters

- `dataset_id` (string, required)

### Body (application/json)

This endpoint expects a CreateDatasetItemsFromTracesRequest.

- `trace_ids` (list of string, required) — Set of trace IDs to add to the dataset
- `enrichment_options` (TraceEnrichmentOptions, required) — Options for enriching trace data
- `evaluators` (list of EvaluatorItem, optional) — Optional evaluators to apply to the created items
- `execution_policy` (ExecutionPolicy, optional)
- `field_mappings` (map from string to string, optional) — Optional mapping of dataset item field name to a path into the trace, e.g. 'input.input_text'. Takes precedence over the fields produced by enrichment_options. Ignored for test suite datasets.
