# Delete a conversation

Requires `query`.

Deleting removes the conversation and all its messages for good. It is gated by the `query` scope, like renaming. It costs no credits.

A person deletes their own chats. An API key deletes the conversations it started, and can send `end_user` as a query parameter to be sure it is that person's. **An API key's conversation also disappears from the workspace's [logs](/docs/platform/logs)** and from their figures: nobody can read it afterwards. To honour a user's request to erase their data, list their conversations with `end_user` and delete each one.

This only deletes your own conversations. The conversations that anonymous visitors had through a widget are kept 90 days and removed with the widget: see [Delete a widget](/docs/api/widgets/delete-widget).

```http
DELETE https://api.lookio.app/v1/conversations/{conversation_id}
```
