# Execute workflow (/api-reference/workflows/executeWorkflowV2)

`POST /api/v2/workflows/{workflowId}/execute`

## Description
Run the active deployment, or set `run.source: "manual"` to run the saved draft. Deployed execution requires workspace read access and OAuth `api:write` scope or an API key; public deployments also allow anonymous synchronous or streamed runs. Manual runs require personal-key or OAuth write access and cannot be async.

Use `async: true` for a queue receipt, or `stream: true` for SSE. For a synchronous run with both flags false, send `Accept: application/x-ndjson` for heartbeat frames and a final frame containing `data`. Timeouts return `200` with `status: "failed"` and `error.code: "TIMEOUT"`; inspect run status. See [Streaming](/workflows/deployment/api#streaming) for event formats. Input descriptions specify compatible modes; invalid combinations return `400`.

Supply `X-Run-Id` to prevent duplicate execution. Reuse returns `409`, without replaying results. A `503` with `error.details.code: "ASYNC_ENQUEUE_AMBIGUOUS"` omits `Retry-After` because the run may already have started. Reconcile using the returned run ID; do not start another run with a new or omitted ID.

OAuth scope: `api:write`.

## Parameters

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

- **x-run-id** (header) — `string`: Run ID for API-key or OAuth callers; ignored for anonymous requests. Reuse it after an uncertain response: a claimed ID returns `409` with `RUN_ID_CONFLICT`, without replaying results. Check Get workflow run, but `404` can persist while the ID remains claimed and does not establish whether execution started. Do not automatically restart with a fresh or omitted ID; either can start another run.

- **x-sim-via** (header) — `string`: Comma-separated workflow identifiers naming the workflow-to-workflow call chain that led to this request. Each hop appends its own workflow id, and Sim sets it automatically; supply it yourself only when relaying an existing chain. A chain at the maximum depth is rejected with `409` and `error.details.code: "CALL_CHAIN_DEPTH_EXCEEDED"`.

## Request Body

Input, workflow-state selection, and execution-mode options. Input descriptions specify compatible modes; invalid combinations return `400`.
