# Batch Forget Facts

> Mark multiple facts as forgotten in a single request

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

Marks multiple facts as forgotten (expired) in a single request. Like [Forget Fact](/features/memorylake/api-reference/facts/forget-fact), this is a soft delete -- facts remain available for audit purposes but are excluded from future retrievals and searches.
