# Get full step output from instance

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.

##### Security

API Token

The preferred authorization scheme for interacting with the Cloudflare API. [Create a token](https://developers.cloudflare.com/fundamentals/api/get-started/create-token/).

**Example:**`Authorization: Bearer Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY`

API Email + API Key

The previous authorization scheme for interacting with the Cloudflare API, used in conjunction with a Global API key.

**Example:**`X-Auth-Email: user@example.com`

The previous authorization scheme for interacting with the Cloudflare API. When possible, use API tokens instead of Global API keys.

**Example:**`X-Auth-Key: 144c9defac04969c7bfad8efaa8ea194`

##### Query ParametersExpand Collapse 

name: string

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

minLength1

type: "step" or "waitForEvent"

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

One of the following:

"step"

"waitForEvent"

attempt: optional number

Specific attempt number to retrieve output or error for.

##### ReturnsExpand Collapse 

errors: array of object { code, message } 

code: number

message: string

messages: array of object { code, message } 

code: number

message: string

result: object { error, status, event\_type, output } 

error: object { message, name } 

Error details when status=‘errored’; null otherwise.

message: string

name: string

status: "queued" or "running" or "paused" or 6 more

One of the following:

"queued"

"running"

"paused"

"errored"

"terminated"

"complete"

"waitingForPause"

"waiting"

"rollingBack"

event\_type: optional string

The event type the step is waiting on, as supplied to step.waitForEvent. Only present when type=‘waitForEvent’.

output: optional unknown

Contains the full step output or waitForEvent payload without truncation. Uses ‘\[REDACTED\]’ for sensitive outputs. Contains a value when status=‘complete’. May contain a ReadableStream when step.do returns one; the response serves stream outputs as application/octet-stream rather than JSON.

success: true

result\_info: optional object { count, per\_page, total\_count, 3 more } 

count: number

per\_page: number

total\_count: number

cursor: optional string

page: optional number

total\_pages: optional number
