# Undo a soft collection delete

> Restores a collection that is still inside its grace window (status=deletion_pending) back to active, cancelling the… (POST /v1/collections/{id}/restore)

Source: https://sightradar.com/docs/api/collections/undo-a-soft-collection-delete

Restores a collection that is still inside its grace window
(`status=deletion_pending`) back to `active`, cancelling the scheduled
purge. The collection keeps the same incarnation, and any batch work that
was paused by the delete resumes. Free and idempotent.

Returns 409 once the purge has actually started (`status=deleting`) —
vectors are being erased at that point, so a restore could not honestly
return the collection intact. Also 409 for a compliance-class erasure,
which is deliberately not restorable.

curl -X POST "https://api.sightradar.com/v1/collections/$ID/restore" \
