# 遗忘 Actor 事实

> 将 Actor 级别的事实标记为已遗忘而不删除它

```
POST /openapi/memorylake/api/v3/workspaces/{workspaceId}/actors/{actorId}/facts/{factId}/forget
```

将 Actor 级别的事实标记为已遗忘（已过期），而不永久删除它。该事实仍可用于审计目的，但会从未来的检索和搜索中排除。要一次遗忘多个 Actor 事实，请使用[批量遗忘 Actor 事实](/features/memorylake/api-reference/facts/batch-forget-actor-facts)。
