Sheet

UUID of the sheet. Pass as `{sheet_id}` on every sheet-scoped endpoint, and as `target_sheet_id` when another sheet routes data here via `send_to_sheet`.

UUID of the parent workflow this sheet belongs to.

Sheet name as set at creation. Not required to be unique within a workflow.

`true` for the workflow's main sheet — auto-created with the workflow, always present, cannot be deleted separately, and has `sheet_id === workflow_id`. `false` for additional sheets added via Create Sheet.

When `true` (default), the sheet's action chain runs automatically whenever new data rows arrive (via Add Data Rows or via a `send_to_sheet` action on another sheet). When `false`, runs must be triggered explicitly with Run Rows.

When `true` (default), a row with input column values identical to a previously-run row reuses the previous row's outputs instead of re-running the action chain. Matching compares every input column value on the row as a string, after variable references are resolved.

Earliest date (`YYYY-MM-DD`, UTC) from which cached runs are considered fresh. Runs performed on or after this date are reusable; runs performed before are ignored even when inputs match. Ignored when `cache_enabled` is `false`. `null` means all cached runs are considered fresh regardless of age.
