# Get Pipeline Execution

`GET /api/v1/pipelines/executions/{execution_id}`

Poll execution status. Returns per-step status with lookup keys for partial results.

Decision rule: Check PG PipelineExecution.status first.
- If terminal (completed/failed): return from PostgreSQL (post-sync, complete data)
- If running/pending: read Firestore for real-time step status

## Path parameters

- `execution_id` string, required

## Cookies

- `wos-session` string
- `datalab_active_team` string

## Response `200`
