# Async Bulk

> Delete all matching QStash DLQ messages in a bulk action.

`POST /v2/dlq/bulkDelete`

The request returns after creating the action. Use its `actionId` with [Get a Bulk Action](/qstash/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.
