# Undo a board import

Roll one import batch back: delete exactly the rows that run CREATED and nothing else — never a row it merely updated, and never a row somebody typed. Answers `{run, removed, kept}`. Refused with 409 `import_running` when the run never settled and 409 `already_undone` when the batch has been rolled back before, because "they were gone before you asked" and "I removed them" are different answers. Get the runId from GET /v1/boards/:id/imports.

Access class: `board:write`.

## Endpoint
