# Get Query Results

GET https://app.polytomic.com/api/queries/{id}

Fetches the latest status for a submitted query and, once complete, returns fields and paginated results.

This endpoint is the second step of the query-runner flow. First call
[`POST /api/connections/{connection_id}/query`](../../../api-reference/query-runner/run-query),
then poll this endpoint with the returned ID.

Results may be paginated across multiple blobs. When that happens, use the
opaque `links.next` and `links.previous` URLs exactly as returned. Do not try to
construct the `page` token yourself.

If the query is still running, the response may include only status metadata.
The terminal statuses are `done`, `failed`, and `unknown`. An `unknown` status
means execution started, but its durable terminal result was lost or expired.
Stop polling when you receive any terminal status.

If the task is complete but the caller is not the same user that created it,
the endpoint returns `404`.
