# 批量遗忘事实

> 在单个请求中将多个事实标记为已遗忘

```
POST /openapi/memorylake/api/v3/workspaces/{workspaceId}/projects/{projectId}/memories/facts/forget
```

在单个请求中将多个事实标记为已遗忘（已过期）。与[遗忘事实](/features/memorylake/api-reference/facts/forget-fact)类似，这是一种软删除——事实仍可用于审计目的，但会从未来的检索和搜索中排除。

<Note>
  **所需权限：** `project:mem_delete`
