mixvel-ndc-client

This module facilitates the work with MixVel API. Currently, it supports XML request generation for basic operations like search, book, and ticket issuing.

Installation

To start using the module, install it via npm

1npm i mixvel-ndc-client

Usage

Currently, you can use the module for XML request generation. Here is the list of supported actions:

• search flights (OW, RT, and complex routes are supported)
• price selected flight and receive alternative pricing options
• book a flight (adult, child, infant, and subsidized categories are supported)
• issue tickets for a booked flight
• cancel an unpaid booking
• view a booking
• request a refund calculation
• perform a full refund
• list fare rules for a chosen flight

For every action listed above, you can generate a valid request containing XML body and endpoint, ready to send to the MixVel server.

At the moment, sending out requests and handling responses is out of the module's scope.

Request object

Each of the available methods returns a MixvelRequest object looking like following:

1MixvelRequest = {
2    "headers": {}, // HTTP request headers
3    "body": string, // request payload, i.e. XML 
4    "options": {
5        "method": "GET" | "POST",
6        "endpoint": string // relative endploing path, e.g. "api/order/Create" 
7    }
8}

Headers

To add headers you may use addHeader method:

1MixvelRequest.addHeader("Content-Type", "application/xml")

Basic flow

• Normally, you would start with a search request. Provide a route (either one-way, return, or complex), travelers, and optionally service class and desired airlines.
• Once you've got the offers list, you may request a price for any of these, using OfferID and OfferItemID list from the response.
• Now, you may create a booking providing travelers info for selected offers. Note that travelers' count must equal the number of travelers you searched.
• Booking has its mixvel order id, which you can use for a tickets issue, cancel or retrieve requests.

Examples

Create a search request

MOW LED return flight for 2 adults 1 child and 1 infant on lap

1getSearchRequest({
2    travelers: [
3        {ptc: 'ADULT', age: "30", id: "1"},
4        {ptc: 'ADULT', age: "30", id: "2"},
5        {ptc: 'CHILD', age: "5", id: "3"},
6        {ptc: 'INFANT', age: "1", id: "4"},
7    ],
8    originDestinations: [
9        {from: "MOW", to: "LED", dateRangeEnd: new Date("2021-12-12"), dateRangeStart: new Date("2021-12-12")},
10        {from: "LED", to: "MOW", dateRangeEnd: new Date("2021-12-15"), dateRangeStart: new Date("2021-12-15")}
11    ],
12    cabin: "ECONOMY",
13    preferredCarriers: null
14})
15    .body // return XML payload ready to send

7        {from: "LED", to: "MOW", dateRangeEnd: new Date("2021-12-15"), dateRangeStart: new Date("2021-12-15")}
8    ],
9    cabin: "BUSINESS",
10    preferredCarriers: ["SU"]
11})
12    .body // return XML payload ready to send

Price selected offer

Having received an offer id and per passenger offer items, you may create a price request.

1getPriceRequest({
2    offerId: 'SOME-OFFER',
3    offerItemIds: ['ADULT-OFFER-ITEM', 'CHILD-OFFER-ITEM']
4})

Book an offer

Book an offer for 1 ADT RT

1getBookRequest({

2    offerId: 'SOME-OFFER',

3    offerItemIds: [{id: 'OFFER-1', ptc: "ADULT"}],

4    passengers: [
5        {

6            ptc: "ADULT",

7            personalInfo: {

8                firstName: 'Test',

9                middleName: 'Test',

10                lastName: 'Test',

11                gender: "M",

12                dob: new Date('1999-02-15'),
13            },

14            identityDocument: {

15                type: "PASSPORT",

16                dateOfIssue: new Date('2015-02-15'),

17                dateOfExpiry: new Date('2025-02-15'),

18                issuingCountry: 'RU',

19                number: '12345'
20            },

21            contacts: {

22                email: 'test@test.test',

23                phoneNumber: '89112311441'
24            }
25        }
26    ]
27})

JSON vs XML

To provide convenient request handling the module utilizes JSON for the request generation and converts JSON to XML document at the end of a generation process. Currently, conversion is handled by xml2js module.
