# Confirm a Reservation

Confirms a reservation by assigning an available charging station and locking a connector. Charge usually calls this automatically about 30 minutes before the preferred charging window, but you can call it manually when needed.

  ```bash cURL theme={null}
  curl -X POST https://api.chargeapi.co/v1/reservations/res_lcrRzkcv6cLEFu2g1iGk7DSkZA1yskj6/confirm \
    -H "Authorization: Bearer ch_sk_test_..." \
    --json '{
