Initialization

Start the SDK once with your bot key and market, for example when your app launches. start does not load the chat yet: the chat page is created the first time the chat is shown. It does start the SDK's usage metrics and error reports, so if your app needs the user's consent for those, call start once the user has given it, see Privacy and Data

Start the SDK

iOS

Android

Flutter

React Native

import KindlyWebView

KindlyWebViewSDK.start(botKey: "YOUR_BOT_KEY", languageCode: "en", market: "general")

Call it from application(_:didFinishLaunchingWithOptions:), from your SwiftUI App's initializer or wherever your app starts. Every member of KindlyWebViewSDK is static and can be called from any thread

A value in the wrong format is refused with an error in the log, and the call does nothing

import ai.kindly.webview.KindlyWebViewSDK

class App : Application() {
    override fun onCreate() {
        super.onCreate()
        KindlyWebViewSDK.start(
            application = this,
            botKey = "YOUR_BOT_KEY",
            languageCode = "en",
            market = "general",
        )
    }
}

Register the class with android:name=".App" on the <application> element of your manifest. Every function can be called from any thread, and the SDK moves to the main thread itself

A value in the wrong format is refused with an error in the log, and the call does nothing

import 'package:flutter/widgets.dart';
import 'package:kindly_webview/kindly_webview.dart';

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await KindlyWebViewSDK.start(botKey: 'YOUR_BOT_KEY', market: 'general', languageCode: 'en');
  runApp(const MyApp());
}

WidgetsFlutterBinding.ensureInitialized() lets a plugin call run before runApp. A value that is blank or in the wrong format throws an ArgumentError naming it, before anything changes, the auth callbacks included

The auth and link callbacks reach the Flutter engine whose Dart code last called start. An engine that never calls start, such as the background engine a messaging or work manager plugin creates, never receives them. After a hot restart, call start and setDelegate again so the new isolate's callbacks are registered. When the engine that called start goes away, the chat gets no token and links open outside the app until another engine calls start

import { KindlyWebViewSDK } from '@kindly-ai/react-native-webview';

await KindlyWebViewSDK.start({
  botKey: 'YOUR_BOT_KEY',
  market: 'general',
  languageCode: 'en',
});

A value in the wrong format rejects with INVALID_ARGUMENT before anything reaches the native SDK

The package answers the native SDK's requests for tokens and link decisions from the JavaScript runtime that is running. After a reload, call start and setDelegate again, as your app's startup code normally does: until then the chat gets no token and links open outside the app

languageCode defaults to en. The bot key, market and language code are trimmed first. A bot key is 8 to 64 letters, digits and hyphens, a market 1 to 64 letters, digits, _ and -, and a language code looks like en, nb or pt-BR. The market must be one configured for the bot, see Markets

Calling start again

Calling start again with the same bot key and market keeps the live chat and replaces only the language and the auth provider. The language applies to the next chat page; to switch the live chat, pass a language when you Launch Chat. A call without an auth provider leaves the chat without one, so pass it on every call

A different bot key or market closes the chat and starts over. The old conversation stays stored for when you switch back

Authenticated chats

Pass an auth provider to start when the chat should know who your user is, see Authentication
