# Resume workflow run (/api-reference/workflow-runs/resumeWorkflowRunV2)

`POST /api/v2/workflows/{workflowId}/runs/{runId}/resume`

## Description
Resume one human-in-the-loop pause with workspace write access. The resumed attempt receives a new run ID and returns a synchronous result or queue receipt. A run that originally streamed resumes asynchronously through v2; this endpoint returns no SSE stream.

OAuth scope: `api:write`.

## Parameters

- **workflowId** (path) (required) — `string`: Unique workflow identifier.

- **runId** (path) (required) — `string`: Unique workflow run identifier.

## Request Body

Pause context and optional input used to resume a workflow run.
