Example

{
  "id": "notify-all",
  "type": "parallel",
  "branches": {
    "email": [
      {
        "id": "send-email",
        "type": "action",
        "action": "colossal/send_email",
        "parameters": { "to": "{{payload.customer_email}}" }
      }
    ],
    "slack": [
      {
        "id": "notify-slack",
        "type": "action",
        "action": "slack/send_message",
        "parameters": { "channel": "#orders" }
      }
    ]
  },
  "next": "continue-after-notifications"
}
Each branch runs independently. If one branch fails, other branches continue to completion. The parallel step’s overall status depends on whether all branches succeed.
