# Resume

The **Resume** action allows you to continue a failed workflow run from the exact point of failure, preserving all successfully completed steps and their results.

This approach is ideal when:

* The workflow has long-running or resource-intensive steps that have already succeeded.
* You want to preserve progress and avoid re-executing successful operations.
* The failure was a temporary issue that can now be resolved.

You can perform this action programmatically as well:

<CodeGroup>
  ```typescript TypeScript theme={"system"}
  import { Client } from "@upstash/workflow";

  const client = new Client({ token: "<WORKFLOW_TOKEN>" });

  await client.dlq.resume({
    dlqId: "dlq-12345",
    retries: 3,
  });
  ```
</CodeGroup>

<Note>
  You can modify workflow code as long as changes occur **after** the failed steps.
  Changes to steps prior to the failure are not allowed and may break the workflow.
