# Run Query

POST https://app.polytomic.com/api/connections/{connection_id}/query
Content-Type: application/json

Submits a query for asynchronous execution against the connection.

This endpoint returns immediately with a query task ID. It does not wait for
the query to finish. Poll [`GET /api/queries/{id}`](../../../../api-reference/query-runner/get-query) until `status`
reaches `done`, `failed`, or `unknown`. These statuses are terminal.

Only the user who created the query can fetch its results later. Query results
are stored temporarily and may expire; use the `expires` field from the result
endpoint to understand how long they will remain available.
