How to differentiate a local pickup vs. local delivery in the fulfillment process?

How do we tell the difference between a local pickup and a local delivery? As you can see below this is a pickup:

json
{
  "id": 3737786155157,
  "code": "SantaVenera",
  "phone": null,
  "price": "0.00",
  "title": "SantaVenera",
  "source": "shopify",
  "price_set": {
    "shop_money": {
      "amount": "0.00",
      "currency_code": "EUR"
    },
    "presentment_money": {
      "amount": "0.00",
      "currency_code": "EUR"
    }
  },
  "tax_lines": [
    {
      "rate": 0.18,
      "price": "0.00",
      "title": "MT VAT",
      "price_set": {
        "shop_money": {
          "amount": "0.00",
          "currency_code": "EUR"
        },
        "presentment_money": {
          "amount": "0.00",
          "currency_code": "EUR"
        }
      },
      "channel_liable": false
    }
  ],
  "discounted_price": "0.00",
  "delivery_category": null,
  "carrier_identifier": "650f1a14fa979ec5c74d063e968411d4",
  "discount_allocations": [
  ],
  "discounted_price_set": {
    "shop_money": {
      "amount": "0.00",
      "currency_code": "EUR"
    },
    "presentment_money": {
      "amount": "0.00",
      "currency_code": "EUR"
    }
  },
  "requested_fulfillment_service_id": null
}

And this is a local delivery, which is identical with no way to tell the two apart.
