## Get full step output from instance

`client.workflows.instances.step(stringworkflowName, stringinstanceId, InstanceStepParamsparams, RequestOptionsoptions?): InstanceStepResponse`

**get** `/accounts/{account_id}/workflows/{workflow_name}/instances/{instance_id}/step`

Retrieves the full, untruncated output for a specific step on a workflow instance. Returns a flat status-shaped JSON body with step `status` ('running' | 'waiting' | 'complete' | 'errored'), `error` (nullable), and `output` (the step value, or null while running/waiting/errored). When the step returned a ReadableStream from step.do, the response is served as 'application/octet-stream' with the raw bytes as the body instead of JSON. A `status='running'` response with non-null `error` indicates the step is currently retrying after a prior attempt failed.

### Parameters

- `workflowName: string`

- `instanceId: string`

  Instance identifier. User-created instances match `^[a-zA-Z0-9_][a-zA-Z0-9-_]*$` (max 100 characters); cron-triggered instances can use a longer, system-generated id derived from the cron expression.

- `params: InstanceStepParams`

  - `account_id: string`

    Path param

  - `name: string`

    Query param: Exact step name from the instance logs response, including the generated counter suffix.

  - `type: "step" | "waitForEvent"`

    Query param: Step type to disambiguate step.do and waitForEvent entries that share the same name.

    - `"step"`

    - `"waitForEvent"`

  - `attempt?: number`

    Query param: Specific attempt number to retrieve output or error for.

### Returns

- `InstanceStepResponse`

  - `error: Error | null`

    Error details when status='errored'; null otherwise.

    - `message: string`

    - `name: string`

  - `status: "queued" | "running" | "paused" | 6 more`

    - `"queued"`

    - `"running"`

    - `"paused"`

    - `"errored"`

    - `"terminated"`

    - `"complete"`

    - `"waitingForPause"`

    - `"waiting"`

    - `"rollingBack"`

  - `output?: unknown`

    Full step output or waitForEvent payload without truncation. Sensitive outputs are returned as '[REDACTED]'. Populated when status='complete'. May be a ReadableStream when the step returned one from step.do; stream outputs are served as application/octet-stream rather than JSON.

### Example

```node
import Cloudflare from 'cloudflare';

const client = new Cloudflare({
  apiToken: process.env['CLOUDFLARE_API_TOKEN'], // This is the default and can be omitted
});

const response = await client.workflows.instances.step('x', 'x', {
  account_id: 'account_id',
  name: 'x',
  type: 'step',
});

console.log(response.error);
```
