# Cancel a pending SNCF Connect train option (pre-reservation)

Automatically cancel a pending SNCF Connect train option (pre-reservation) on sncf-connect.com. Cancels a pending free option (pre-reservation) on SNCF Connect, releasing the hold it placed on a train's price and seat. Defaults to a dry run: it reports the option it would cancel and backs out without touching it. Pass confirm=true to actually cancel, which is irreversible — the blocked price is lost. When more than one option is pending, `match` picks the right one by part of its destination and/or travel date. Requires being signed in to SNCF Connect. Runs only via the local browser extension, not the hosted cloud browser.
