    ]
  }
}

2- second i am completing the order using this api
PUT /admin/api/2023-04/draft_orders/DRAFT_ORDER_ID/complete.json

3- now i wanna make a transaction using this api
POST /admin/api/2023-04/orders/{order_id}/transactions.json

and the payload should be like this

{
  "transaction": {
    "kind": "sale",
    "status": "success",
    "amount": "IQD19,500.000",
    "currency": "IQD",
    "gateway": "manual"
  }
}

what i need more is the parent_id based on the shopify docs

https://shopify.dev/docs/api/admin-rest/2023-04/resources/transaction#post-orders-order-id-transactions
how can i get it ?
