Get full step output from instance

client.Workflows.Instances.Step(ctx, workflowName, instanceID, params) (*InstanceStepResponse, error)
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.

workflowName string
maxLength64
minLength1
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.

AccountID param.Field[string]

Path param

Name param.Field[string]

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

minLength1
Type param.Field[InstanceStepParamsType]

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

const InstanceStepParamsTypeStep InstanceStepParamsType = "step"
const InstanceStepParamsTypeWaitForEvent InstanceStepParamsType = "waitForEvent"
Attempt param.Field[int64]Optional

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

type InstanceStepResponse struct{…}
Error InstanceStepResponseError

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

Message string
Name string
Status InstanceStepResponseStatus
One of the following:
const InstanceStepResponseStatusQueued InstanceStepResponseStatus = "queued"
const InstanceStepResponseStatusRunning InstanceStepResponseStatus = "running"
const InstanceStepResponseStatusPaused InstanceStepResponseStatus = "paused"
const InstanceStepResponseStatusErrored InstanceStepResponseStatus = "errored"
const InstanceStepResponseStatusTerminated InstanceStepResponseStatus = "terminated"
const InstanceStepResponseStatusComplete InstanceStepResponseStatus = "complete"
const InstanceStepResponseStatusWaitingForPause InstanceStepResponseStatus = "waitingForPause"
const InstanceStepResponseStatusWaiting InstanceStepResponseStatus = "waiting"
const InstanceStepResponseStatusRollingBack InstanceStepResponseStatus = "rollingBack"
Output unknownOptional

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.
