iOS Chatbot SDK



To integrate YMChatbot into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'YMChat'
Supported iOS versions:

iOS 12, 13 and 14

Basic Usage#

Import the YMChat framework in the Swift file

import YMChat

After the framework is imported the bot can be presented with few lines as below

do {
let config = YMConfig(botId: "x1234567890")
YMChat.shared.config = config
try YMChat.shared.startChatbot(on: self)
} catch {
print("Error occured while loading chatbot \(error)")


YMConfig can be used to set the bot id and other bot related settings. It is recommended to set all appropriate config before starting the bot

Initialize YMConfig#

YMConfig requires botID to initialize. All other settings are optional.

let config = YMConfig(botId: "<bot-id>")

YM AuthenticationToken#

ymAuthenticationToken is used to associate an identity of the user with the chat bot.

Whenever chatbot is launched with ymAuthenticationToken it will load the previous chats associated with this user since inception.

config.ymAuthenticationToken = "your-token"

Note: History will load only when Show history flag is enabled in the channel settings

Push Notifications#

YMChat supports firebase notifications. Assign your FCM token to deviceToken

config.deviceToken = "your-firebase-device-token"

Note: Firebase service account key is required to send notifications. You can share the service account key with us. More info here


Additional information can be passed in the form of key value pair from app to bot using payload.

config.payload = ["name": "", "device-type": "mobile"]

Payload can be used to pass information from host app to bot. The payload dictionary should be JSON compatible else an error will be thrown

For passing data from bot to app refer bot Bot Events

payload security

Payload is securely passed in HTTPS post request to protect the information passed in it

On Premise deployments#

Your on-prem deployment URL can be set to customBaseUrl

config.customBaseUrl = ""

Speech to Text#

Speech to text can be enabled by setting the enableSpeech flag. Default value is false

config.enableSpeech = true

If you are adding Speech recognization, add following snippet to Info.plist of the host app

<string>Your microphone will be used to record your speech when you use the Voice feature.</string>
<string>Speech recognition will be used to determine which words you speak into this device&apos;s microphone.</string>

Start chatbot#

Once the config is set, chat bot can be presented by calling startChatbot() method and passing your view controller as an argument

do {
try YMChat.shared.startChatbot(on: self)
} catch {
print("Error occured while loading chatbot \(error)")

Bot Events#

Bot events are used to pass information from bot to app. For passing events from app to bot refer Payload

Events from bot can be handled using delegate pattern.

YMChat.shared.delegate = self

Once the delegate is assigned define the eventResponse(_:) function. The handler class should conform to YMChatDelegate

func onEventFromBot(_ response: YMBotEventResponse) {
print("Event received \(response)")
if response.code == "code-from-bot" {
print("Even from a bot has been received",

Bot close event#

Bot close event is separetly sent and it can be handled in following way. The handler class should conform to YMChatDelegate

func onBotClose() {
print("Bot closed")

Close bot#

Bot can be programatically closed using closeBot() function



Logging can be enabled to understand the code flow and to fix bugs.

YMChat.shared.enableLogging = true

Demo App#

A demo has been created to better understand the integration of SDK in iOS app
