# client.dlq.resume

The `dlq.resume` method resumes one or more workflow runs from the **Dead Letter Queue (DLQ)** at the point where they previously failed.
This allows you to continue execution from the failed step instead of restarting the workflow from the beginning.

## Arguments

<ParamField body="dlqId" type="string|string[]" required>
  The DLQ entry ID or list of IDs to resume.
  Use the `dlqId` field from messages returned by `client.dlq.list()`.
</ParamField>

<ParamField body="flowControl" type="object" optional>
  An optional flow control configuration to limit concurrency and execution rate
  of resumed workflow runs.

  See [Flow Control](/workflow/features/flow-control) for details.

  <Expandable title="properties">
    <ParamField body="key" type="string">
      A logical grouping key that identifies which resumed runs share the same flow control limits.
    </ParamField>

    <ParamField body="rate" type="number">
      The maximum number of allowed resumption requests per second.
    </ParamField>

    <ParamField body="parallelism" type="number">
      The maximum number of resumed runs that can execute concurrently.
    </ParamField>

    <ParamField body="period" type="string|number">
      The time window used to enforce the defined rate limit. Default is `1s`.
    </ParamField>
  </Expandable>
</ParamField>

<ParamField body="retries" type="number" optional>
  Number of retry attempts to apply when resuming the workflow run.
  Defaults to `3` if not provided.
</ParamField>

## Response

`client.dlq.resume()` returns one or more objects with details of the resumed workflow run(s):

<ResponseField name="workflowRuns" type="object[]">
  <Expandable defaultOpen>
    <ResponseField name="workflowRunId" type="string">
      The ID of the workflow run resumed from the DLQ message.
    </ResponseField>

    <ResponseField name="workflowCreatedAt" type="number">
      The Unix timestamp (in milliseconds) when the resumed run was created.
    </ResponseField>
  </Expandable>
</ResponseField>

## Usage

<CodeGroup>
  ```ts Single theme={null}
  const { messages } = await client.dlq.list();

  const response = await client.dlq.resume({
    dlqId: messages[0].dlqId, // Use the dlqId from the message
    flowControl: {
      key: "my-flow-control-key",
      value: "my-flow-control-value",
    },
    retries: 3,
  });

  ```

  ```ts Multiple theme={null}
  const responses = await client.dlq.resume({
    dlqId: ["dlq-12345", "dlq-67890"],
    retries: 5,
  });
