How it works

The online orders API is a mechanism that allows importing online orders from "external system" (such as e-shops or food delivery platforms) to the PORTOS system.

The PORTOS system acts as an "client" initiating HTTP requests targeting the external system, that acts as an "server" and handles the following requests:

1. Fetch unprocessed orders

2. Process order

After unprocessed order is fetched, cashier is requested to process (either accept or reject) the order trough the PORTOS application. After cashier confirms or rejects the order, PORTOS application will initiate second request (process order) to the external system.

The PORTOS system expects that responses from external system follows data format described below.

Fetch unprocessed orders

GET {external-system}{unprocessed-orders-url}

The PORTOS system will periodically fetch the unprocessed orders from the external system, by initiating GET HTTP request to the external system. External system returns the unprocessed orders for given venue. If the collection of orders is paginated by the external system (so response does not contain all unprocessed orders), the most oldest orders should be returned.

• external system process order URL: https://the-foo-bar.sk/process_order

• API key is: my-token

Step 1: Fetching unprocessed orders

The external system returns following payload as an response:

    "totalPrice": 13.96,
    "note": null
  }
]

As we can see, the external systems returns two unprocessed orders.

Step 2: Order acceptation

The PORTOS will mark first order as accepted by requesting following URL:

POST https://the-foo-bar.sk/process_order?version=1&key=my-token&externalId=b478396ad654&status=accepted&estimatedCompletionAt=2021-02-01T13%3A01%3A00.000Z

Please note that all query parameters are URL encoded. In URL above, the estimatedCompletionAt query parameter value 2021-02-01T13:01:00.000Z is URL encoded as 2021-02-01T13%3A01%3A00.000Z.

Step 3: Fetching unprocessed orders

The PORTOS will request unprocessed requests again:

GET https://the-foo-bar.sk/unprocessed_orders?version=1&key=my-token

The external system returns following payload as an response:

[
  {
    "externalId": "6a2ad048e32d",
    "type": "takeAway",
    "delivery": null,
    "createdAt": "2021-02-01T12:01:00.000Z",
    "scheduledAt": "2021-02-01T13:00:00.000Z",
    "customer": {
      "name": "John Doe",
      "phone": "[phone]",
      "email": "[e-mail]"
    },
    "products": [
      {
        "id": "2345",
        "name": "Fries",
        "quantity": 2,
        "baseUnitPrice": 4.99,
        "note": "",
        "additions": [
          {
            "id": "11024",
            "name": "Ketchup",
            "quantity": 1,
            "unitPrice": 1.99,
            "note": ""
          }
        ]
      }
    ],
    "currency": "EUR",
    "payment": {
      "isSettled": false,
      "method": null
    },
    "wrappingFee": 0,
    "packagingDeposit": 0,
    "tip": 0,
    "totalPrice": 13.96,
    "note": null
  }
]

The recently accepted order no longer appears in unprocessed orders collection.

Step 4: Order rejection

The PORTOS will mark remaining order as rejected by requesting following URL:

POST https://the-foo-bar.sk/process_order?version=1&key=my-token&externalId=6a2ad048e32d&status=rejected&rejectionReason=The%20food%20is%20out%20of%20stock.

Please note that all query parameters are URL encoded. In URL above, the rejectionReason query parameter value The food is out of stock. is URL encoded as The%20food%20is%20out%20of%20stock..

Step 5: Fetching unprocessed orders

The PORTOS will request unprocessed requests again:

GET https://the-foo-bar.sk/unprocessed_orders?version=1&key=my-token

All requests has been processed (rejected or accepted). The external system returns empty collection as an response.
