Intro

In-app chat is the mobile component for connecting and interacting with Infobip's LiveChat product. In-app chat is built on top of Mobile Messaging SDK and that's why Mobile Messaging should be included into your application and properly configured. In-app chat requires from you a careful setup, both in your mobile app and in Infobip's portal. The following steps must be prepared in order to ensure the chat communication:

  1. Include and setup Mobile Messaging SDK plugin in your application. If you haven't already, please follow its Quick start guide carefully. Only by being able to receive a pushRegistrationId in your device, you'll be able to successfully connect to In-app chat in the next steps.

  2. Create a LiveChat Widget and link Mobile Messaging application profile you created in step 1 to the widget configuration.

  3. Setup In-app chat for Mobile Messaging SDK plugin, put inAppChatEnabled: true in configuration:

InfobipMobilemessaging.init(Configuration(
        ...
        inAppChatEnabled: true,
        ...
));

Display In-app chat view

By default in-app chat screen will be displayed with toolbar and back button at the left corner for closing the screen.

InfobipMobilemessaging.showChat()
android_chat_screen ios_chat_screen
Examples of Android and iOS in-app-chat
You can configure presenting options for iOS, so that in-app chat screen will be displayed with toolbar and x button for iOS. 
InfobipMobilemessaging.showChat(shouldBePresentedModallyIOS: true);

Customize In-app chat view

You can define your own custom appearance for chat view: It is part of Configuration object passed to InfobipMobilemessaging.init(). If it is undefined, its settings will be taken from web widget configuration (as defined in Infobip Portal). We offer an example on chat customization in the example application.

Handle notification taps

Mobile Messaging Plugin has notificationTapped event, which will be sent when user opens the app by tapping on the notification alert. Note that chat messages may be recognised by chat attribute:

InfobipMobilemessaging.on(
    LibraryEvent.notificationTapped,
    (Message message) => {
          if (message.chat) {print('Chat message tapped')}
        });

In-app chat events

In-app chat library supports all core SDK library events plus following chat specific events: All In-app chat events are currently supported only in Android.

Event Parameters Description
unreadMessageCounterUpdated Unread messages count Triggered when number of unread messages is changed.
chatViewStateChanged In-app chat view name: LOADING, THREAD_LIST, LOADING_THREAD, THREAD, CLOSED_THREAD, SINGLE_MODE_THREAD, UNKNOWN Triggered when when view in InAppChat is changed.
chatConfigurationSynced Triggered when chat configuration is synchronized. (Note: Android only)
chatLivechatRegistrationIdUpdated Livechat registration id Triggered when livechat registration id is updated. (Note: Android only)

Library events can be subscribed on using the following code snippet:

import 'package:infobip_mobilemessaging/models/library_event.dart';

InfobipMobilemessaging.on(
    LibraryEvent.'<event name>',
    (event) => {
        print('Event received: ' + event.toString());
    });

Sending attachments

We've added sending attachments support, more info in iOS SDK docs, Android SDK docs

Attachments preview

For saving attachments to photo library you will need to add additional permissions

Unread chat push messages counter

An API is available to get and reset current unread chat push messages counter. The counter increments each time the application receives chat push message (this usually happens when chat screen is inactive or the application is in background/terminated state). In order to get current counter value use following API:

int counter = await InfobipMobilemessaging.getMessageCounter();

MobileMessaging SDK automatically resets the counter to 0 whenever user opens the chat screen. However, use the following API in case you need to manually reset the counter:

InfobipMobilemessaging.resetMessageCounter();

You can register to the event unreadMessageCounterUpdated with inAppChat.unreadMessageCounterUpdated value, in order to get updates of the counter in runtime.

Changing localization

The predefined messages prompted within the In-app chat (such as status updates, button titles, input field prompt) by default are localized using system locale setting, but can be easily changed providing your locale string with the following formats: "es_ES", "es-ES", "es".

InfobipMobilemessaging.setLanguage("es");

Sending Contextual Data

It is possible to send contextual data / metadata to Infobip’s Conversations via mobile messaging SDK's chat. Data can be sent anytime, several times, with only one restriction: the chat must be already loaded and presented, and the communication should have started (meaning, there are messages visible and not the initial “Start the chat” button). Sent data will be automatically linked to the conversationId and accountId internally.

There are two parameters:

  1. The mandatory data, sent as string, in the format of Javascript objects and values (for guidance, it must be accepted by JSON.stringify())
  2. And optionally, an "all multithread strategy" that can be left empty, and will use false (ACTIVE) as default. Possible values are: metadata sent to "ACTIVE" conversation for the widget (with false), or to "ALL" non closed conversations for the widget (with true).

Usage:

InfobipMobilemessaging.sendContextualData("{ exampleKey: 'InAppChat Metadata Value Example' }", false);

Multiple chat threads

Default LiveChat widget works with single chat thread, one customer can only have one single open conversation. But the LiveChat widget settings page offers option to enable multiple chat threads.

Multithread setting

When the setting above is enabled, the In-app chat UI will automatically offer in mobile:

  • A list (initially empty) of all the unsolved conversation threads the user has opened.
  • A button to "Start new chat" thread.
  • A navigation to each specific conversation thread, to open particular chat view tap on conversation thread in the list.
Threads list

The functionality for multiple chat threads works out of the box: there is no need for extra implementation in the mobile integrator's side.

Authenticated chat

It is possible to authenticate a user before accessing the In-app chat, given you have enabled this feature in the LiveChat widget.

Livechat widget JWT authentication setup

The authentication is accomplished by combining the Mobile Messaging SDK personalisation method with a JWT (JSON Web Token). The token needs to be generated by your end (see instructions here).

The authentication will use a unique identifier for your user, that can be an email address, a phone number, or an external identifier. It is crucial for this identifier to be valid, and to match the identity defined in the UserIdentity you passed in Mobile Messaging SDK personalisation call - there will be an authentication error otherwise.

Mobile messaging provides setJwt() method to give In-app chat the ability to authenticate users. In Android, provided JWT can be used multiple times during In-app chat lifetime, due to various events like screen orientation change, internet re-connection and others. You must ensure JWT expiration time is more than In-app chat lifetime.

/*
1 - The customer authenticate in your system, and you recognise his/her unique identifier
2 - You call personalise (InfobipMobilemessaging.personalize()) with this unique identifier (and optionally, with other attributes such as first name, second name, etc)
3 - Now you can display the chat as an authenticated user by doing the following:
*/

InfobipMobilemessaging.setJwt("your JWT");
InfobipMobilemessaging.showChat();

Chat and push notifications

In-app chat decides automatically when to send push notifications for incoming messages events based on the following rules:

  • If In-app chat is not loaded/disconnected => push notifications will be sent.
  • If your app is in the background or a device is locked regardless of its connection status => push notifications will be sent.
  • If the app is in the foreground and In-app chat is loaded/connected => push notification will NOT be sent.

In Android In-app chat connection is established and stopped based on component lifecycle. Chat connection is active only when Lifecycle.State is at least Lifecycle.State.STARTED. Chat connection is stopped when Lifecycle.State is below Lifecycle.State.STARTED.

In iOS chat could be loaded/connected but your app may have it hidden (e.g. behind another view) we provide you with the flexibility to control its connection. You can still receive push notifications in the foreground with these methods: stopConnection and restartConnection. Usage example:

InfobipMobilemessaging.showChat();
// Hide the chat, e.g., by displaying a new modal on top of it
InfobipMobilemessaging.stopConnection();
// Push notifications for new message events will start coming to the device
// When you detect that a chat is visible again to a user, you can reload the chat and stop push notifications by invoking: 
InfobipMobilemessaging.restartConnection();
