How to implement logistics in agnostic API

You will receive this payload in the body; the HTTP method used is POST.

{
  "retailerId": "GLGxxjNrvy",
  "integrationId": "abcd-1234-abc-123",
  "postalCode": "89065010",
  "items": [
    { 
      "id": "13",
      "quantity": 1,
      "productId": "123",
      "seller": "loja teste",
      "productReference": "ean1234567890"
    }
  ]
}

You should respond in this format:

{
    "logisticsInfo": [
        {
            "shippingOptions": [
                {
                    "id": "PAC",
                    "name": "PAC",
                    "price": 5,
                    "deliveryChannel": "delivery",
                    "shippingEstimate": "3 dias úteis",
                },
                {
                    "id": "Expresso",
                    "name": "Expresso",
                    "price": 10,
                    "deliveryChannel": "delivery",
                    "shippingEstimate": "10 dias úteis",
                },
               {
                    "id": "Retirada",
                    "name": "Retirada",
                    "price": 0,
                    "deliveryChannel": "pickup-in-store",
                    "shippingEstimate": "Retirada em até 2h",
                }
            ]
        }
    ]
}

Remember: currently Whizz only calculates the shipping cost and informs the buyer, but Whizz does not select the shipping method; this is a rule of our workflow.
