Introduction

LiveChat Customer SDK is a set of tools that helps you build a custom chat widget. Under the hood, it makes use of the LiveChat Customer Chat API. Customer SDK lets you communicate with LiveChat services directly from the browser environment using JavaScript without the need to develop your backend.

Is it for me?

If you need to customize the LiveChat Widget, using LiveChat Customer SDK is
one of the options to do this. If you need a fully customizable solution and you feel
brave, dive into LiveChat Customer SDK. We provide methods and
events for deep integration with the LiveChat environment.

Keep in mind that interacting with this API requires some development skills.

Customer SDK allows you to create frontend apps, so if you're looking for server-side solutions, you should explore the LiveChat Customer Chat API instead.
If you want to dive deeper into the LiveChat Platform, you might find the Platform Overview article handy.

About LiveChat Customer SDK

We provide an asynchronous API. Most methods return a Promise. You can subscribe to the emitted events with the on and off methods.
Not familiar with promises? Read this article to learn more.

We authenticate your sessions with the use of
customer-auth package
and expose the created auth object to the returned SDK instance. In general,
you don't have to worry about it or use the exposed object. If you need to
get the authentication token, you can get it through the SDK like this:

``js
customerSDK.auth.getToken().then(token => {
console.log(token)
})
`

How to start

This tutorial is here to help you get started with LiveChat Customer SDK.

Create an application

First, you need to create an application in
Developer Console (select the _Web app (frontend,
e.g. JavaScript)_ type). Then, you will have to give it the access to the customers:own scope and the correct URI to the Redirect URI whitelist.

Install Customer SDK

You can use the LiveChat Customer SDK in two different ways:

$3

npm install --save @livechat/customer-sdk

Import the SDK in your code:

import * as CustomerSDK from '@livechat/customer-sdk'

Or use the node-style require call:

const CustomerSDK = require('@livechat/customer-sdk')

$3

If you just want to look around and play with the SDK, check out our
sample chat widget implementation.

For the time being you need to register your application in the Developers Console
as a "Web app (frontend, eg. JavaScript)" type. Then, you have to pass the configured redirectUri to the init, along with the regular required properties (organizationId and clientId).

Using the API

To use the API you will first need to create an instance using the init function.
You will need to provide your organizationId and clientId when creating a Customer SDK instance.

Other optional configuration parameters are also available:

| parameters | type | default | description |
| -------------------- | ------------------ | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| organizationId | string | | Your Organization ID, you receive this value when creating a new livechat account. |
| clientId | string | | Your client id, you receive this value when you register your application in the LiveChat Developer Console. |
| autoConnect | boolean | true | Optional; should the library try to reconnect on it's own. |
| groupId | number | 0 | Optional; the id of the group you wish to connect to. |
| uniqueGroups | boolean | false | Optional; by default, the customer's identity is the same for all groups. If you want to create a separate customer identity for each group, set this parameter to true. When set to true, passing a groupId is required. |
| region | 'dal' \| 'fra' | 'dal' | Optional; the server region your license is at. |
| redirectUri | string | | Optional; should only be used inside ReactNative, this is the URI which your webview is redirected to after authorization. |
| customerDataProvider | () => CustomerData | | Optional; should only be used if you need to send customer data during login. In general, updateCustomer() should be prefered for sending customer data. |
| identityProvider | () => CustomerAuth | | Optional; allows for providing own instance of the CustomerAuth object which contains the customer access token handlers. See Custom Identity Provider for more information. |
| page | object | | Optional; customer page information. |
| page.url | string | | Optional; customer page url. |
| page.title | string | | Optional; customer page title. |
| referrer | string | | Optional; page referrer |

CustomerData:

| parameters | type | description |
| ------------- | ------ | ---------------- |
| name | string | Optional |
| email | string | Optional |
| sessionFields | object | Key: value pairs |

CustomerAuth:

| parameters | type | description |
| ------------- | ---------------------- | -------------------------------------------------------------------------------------- |
| getFreshToken | () => Promise | Should resolve with freshly requested customer access token. |
| getToken | () => Promise | Should resolve with currently stored customer access token. |
| hasToken | () => Promise | Should resolve with a boolean value representing if a token has been already acquired. |
| invalidate | () => Promise | Should handle token invalidation and/or clearing the locally cached value. |

The init function will return a Customer SDK instance:

`js
const customerSDK = CustomerSDK.init({
organizationId: ORGANIZATION_ID,
clientId: CLIENT_ID,
})
`

With customerSDK, you can attach events:

`js
customerSDK.on('new_event', newEvent => {
console.log(newEvent)
})
`

Or execute methods:

`js
const chatId = 'OU0V0P0OWT'
customerSDK
.sendEvent({
chatId,
event: {
type: 'message',
text: 'Hi!',
},
})
.then(response => {
console.log(response)
})
.catch(error => {
console.log(error)
})
`

If you want to use LiveChat Customer SDK in React Native, keep in mind that we
use cookies to authenticate your sessions, so we need some sort of browser
environment for that. We've prepared a special wrapper for you to use in React
Native. It opens a WebView component to get an authentication token. All you
have to do is import it from our authentication package (no need to install
it - the SDK depends on it, so you already have it) and mount it in your React
Native application:

`js
import { AuthWebView } from '@livechat/customer-auth'
import { init } from '@livechat/customer-sdk'

export default class App extends React.Component {
customerSDK = null

componentDidMount() {
this.customerSDK = init({
organizationId: ORGANIZATION_ID,
clientId: CLIENT_ID,
redirectUri: REDIRECT_URI,
})
// you can start using customerSDK from now
}

render() {
return (



)
}
}
`

If you are looking for something simpler, you can use a LiveChat for React Native library. This is a React Native component to easily add the LiveChat Widget with basic functionality to your application.

Key Concepts

The LiveChat system includes four basic types of entities - users, chats, threads, and events.

- Chats consist of threads and threads consist of events.
- Threads are parts of chats.
- Users can add events to chats, which then are automatically added to threads.
- Users can participate in many chats at the same time.

Threads are a vital part of the LiveChat architecture.
Grouping events in threads allows us to provide the continuous chat experience (i.e. the Customer always has the option to continue the conversation) while still maintaining smaller, logical chunks of events (e.g. for reporting and caching purposes).
Handling operations such as loading archival events from the chat history can be challenging, but you won't have to worry about managing threads most of the time.
Customer SDK provides wrappers for common tasks and most methods expect to receive chat IDs.
You will only get notified about thread metadata if you explicitly ask for it.

You can read more about key concepts of the LiveChat messaging in the Messaging Overview.

Methods

acceptGreeting

You can use this method to inform that a Customer has seen a greeting. Based on that, the Reports section displays only the greetings seen by Customers instead of all the sent greetings. If a Customer started a chat from a greeting but you didn't execute acceptGreeting method, the greeting counts as seen in Reports anyway.

As arguments to this method you should use uniqueId & greetingId received in the incoming_greeting or connected event.

`js
customerSDK
.acceptGreeting({
greetingId: 7,
uniqueId: 'Q10X0W041P',
})
.then(response => {
console.log(response)
})
.catch(error => {
console.log(error)
})
`

Parameters:

| parameters | type |
| ---------- | ------ |
| greetingId | number |
| uniqueId | string |

$3

- GREETING_NOT_FOUND - a given uniqueId couldn't be found on the server

cancelGreeting

Cancels a greeting (an invitation to the chat). For example, Customers could cancel greetings by clicking close icon on the displayed greeting.

`js
customerSDK
.cancelGreeting({
uniqueId: 'Q10X0W041P',
})
.then(response => {
console.log(response)
})
.catch(error => {
console.log(error)
})
`

Parameters:

| parameters | type |
| ---------- | ------ |
| uniqueId | string |

$3

- GREETING_NOT_FOUND - given uniqueId could not be found on the server

cancelRate

Cancels rate-related thread properties.

`js
customerSDK
.cancelRate({
chatId: 'ON0X0R0L67',
properties: ['score', 'comment'],
})
.then(response => {
console.log(response)
})
.catch(() => {
console.log(error)
})
`

$3

- MISSING_CHAT_THREAD - the targeted chat is empty and has no threads.

connect

autoConnect: false,
})

/ later in the code... /

customerSDK.connect()
`

- You get disconnected for a reason that suspends reconnection attempts (e.g. inactivity_timeout).

`

getChat

Returns the chat data about the requested chat ID together with a single thread's data. If the method is called with the threadId parameter, then this particular thread is being returned. If no threadId is given, the latest thread is automatically returned.

`js
customerSDK
.getChat({

})
.then(chat => {
const { id, access, users, properties, thread } = chat
console.log({ id, access, users, properties, thread })
})
.catch(error => {
console.log(error)
})
`

Parameters:

| parameters | type | description |
| ---------- | ------ | ----------- |
| chatId | string | |
| threadId | string | optional |

Returned value:

| properties | type | description |
| ---------- | -------- | ------------------------------------ |
| id | string | Chat ID |
| access | object | Chat initial access |
| users | object[] | Users objects referenced in the chat |
| properties | object | Chat properties |
| thread | object | |

getChatHistory

Helps loading in historical thread events.

First, call getChatHistory to access the history object of a particular chat.
The returned history object has only one method, next, which gives you a Promise with a { done, value } object.

- done - indicates if there is anything more to load
- value - an object with an array of threads, each containing an array of its events

Then, you can keep calling history.next() multiple times to load previous historical events. They're going to be grouped into threads and might require merging with already loaded events.
This is useful for implementing an infinite scroll or otherwise showing your Customer's archival chats.
Keep in mind, though, that you generally shouldn't call next while the history is loading - we queue those requests, so the previous one must resolve before we proceed with the next one.

The structure such as our history object is called an async iterator.

`js
let wholeChatHistoryLoaded = false

const history = customerSDK.getChatHistory({ chatId: 'OU0V0P0OWT' })

history.next().then(result => {
if (result.done) {
wholeChatHistoryLoaded = true
}

const { threads } = result.value

const events = threads
.map(thread => thread.events || [])
.reduce((acc, current) => acc.concat(current), [])

console.log(events)
})
`

Parameters:
