# Approval

Pause a workflow until a human (or app) approves or rejects it. Drive from the approval-queue archetype or any UI that calls the gateway resumeRun endpoint. The resume payload (e.g. `{ action: "approve" }`) lands on the wait node's `triggerResult` so downstream `if` nodes can branch.

## Workflow Root Example

```json
{
  "nodes": {
    "root": {
      "type": "approval",
      "payload": {},
      "children": [
        "log_event"
      ]
    },
    "log_event": {
      "type": "log",
      "payload": {
        "message": "Triggered at {{$trigger.triggeredAt}}"
      },
      "children": []
    }
  }
}
```

**Reference trigger output**

Downstream nodes can use `{{$trigger.triggeredAt}}` and any result fields listed above. Event triggers usually expose the raw source payload under a field such as `event`, `body`, `trade`, or `raw`.
