# Async Bulk

> Delete all matching failed Workflow runs in a bulk action.

`POST /v2/workflows/dlq/bulkDelete`

The request returns after creating the action. Use its `actionId` with [Get a Bulk Action](/workflow/api-reference/bulk-actions/get-a-bulk-action) to check progress.

Identical filters submitted while an action is already in-progress return the existing action.
