# Async Bulk

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

`POST /v2/dlq/bulkRetry`

Each retry creates a new message with the original body and headers, then removes the original DLQ entry.

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.
