# Get full step output from instance

client.Workflows.Instances.Step(ctx, workflowName, instanceID, params) (\*[InstanceStepResponse](<https://developers.cloudflare.com/api/go/resources/workflows#(resource)%20workflows.instances%20%3E%20(model)%20InstanceStepResponse%20%3E%20(schema)>), 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.

EventType stringOptional

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

Output unknownOptional

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.
