Clickable links delegate

When a user taps a URL, phone number, or email address sent to a conversation, the SDK handles the event automatically by launching the default app capable of completing the action:

• the default browser for a URL
• the default phone app for a phone number
• the default email app for an email address

Note: Only URLs such as https://www.zendesk.com/ are made clickable in the UI. Other URIs such as zendesk://myapp will not be clickable.

You can customize the behavior and change what happens when the user clicks a URL by setting a MessagingDelegate. The shouldHandleUrl function will be called any time the user clicks a URL.

To prevent the SDK from opening the default browser, you should return false when this happens. In that case, you must handle the completion of the action yourself. The function receives two parameters:

• url: the URL that was clicked
• urlSource: an enumeration that describes where in the UI the url was clicked, such as a text message, a carousel item, and so on.

The following snippets show how you can set a MessagingDelegate in Kotlin and Java:

Kotlin

Messaging.setDelegate(object : MessagingDelegate() {
    override fun shouldHandleUrl(url: String, urlSource: UrlSource): Boolean {
        // Your custom action...

        // Return false to prevent the SDK from handling the URL automatically
        // Return true to allow the SDK to handle the URL automatically, even
        // if you have done something custom
        return false
    }
})

Java

Messaging.setDelegate(new MessagingDelegate() {
    @Override
    public boolean shouldHandleUrl(@NotNull String url, @NotNull UrlSource urlSource) {
        // Your custom action...

        // Return false to prevent the SDK from handling the URL automatically
        // Return true to allow the SDK to handle the URL automatically, even
        // if you have done something custom
        return false;
    }
});

Events

The Zendesk SDK for Android provides an event listener ZendeskEventListener where you can listen for any ZendeskEvent emitted from the SDK.

Available Events

ZendeskEvent is a sealed class with a subclass for each event that can currently be emitted. It has the following events:

• UnreadMessageCountChanged
• AuthenticationFailed

UnreadMessageCountChanged

The number of unread messages has changed.

Name	Type	Comment
currentUnreadCount	Int	The current number of unread messages.

AuthenticationFailed

Invoked when an authentication error has occurred on any of the API calls.

Name	Type	Comment
error	Error	Details about the error that occurred.

EventListener

Kotlin

Here is a code sample showing how the the event listener can be used, added and removed:

// To create and use the event listener:
val zendeskEventListener: ZendeskEventListener = ZendeskEventListener {
    zendeskEvent -> when (zendeskEvent) {
        is ZendeskEvent.UnreadMessageCountChanged ->{
            // Your custom action...
        }
        is ZendeskEvent.AuthenticationFailed -> {
            // Your custom action...
        }
        else -> {
           // Default branch for forward compatibility with Zendesk SDK and its `ZendeskEvent` expansion
        }
    }
}

// To add the event listener to your Zendesk instance: 
// (safe for concurrent use)
zendesk.addEventListener(zendeskEventListener)

// To remove the event listener from your Zendesk instance:
// (safe for concurrent use)
zendesk.removeEventListener(zendeskEventListener)

Java

Below is a code sample showing how the the event listener can be used, added and removed.

This includes the ZendeskEventListenerAdapter, an implementation of the ZendeskEventListener designed to provide better support for Java:

// To create and use the event listener:
ZendeskEventListener zendeskEventListener =
    new ZendeskEventListener() {
        @Override
        public void onEvent(@NonNull ZendeskEvent zendeskEvent) {
            if (zendeskEvent instanceof UnreadMessageCountChanged) {
                // Your custom action...
            } else if (zendeskEvent instanceof AuthenticationFailed){
                // Your custom action...
            }
        }
    };
    
// Or using the ZendeskEventListenerAdapter:
ZendeskEventListenerAdapter listenerAdapter = new ZendeskEventListenerAdapter() {
    @Override
    public void onUnreadMessageCountChanged(@NonNull UnreadMessageCountChanged event) {
        super.onUnreadMessageCountChanged(event);
        // Your custom action
    }
};
    
// To add the event listener to your Zendesk instance:
zendesk.addEventListener(zendeskEventListener);

// To remove the event listener from your Zendesk instance:
zendesk.removeEventListener(zendeskEventListener);

EventFlow

Below is a code sample which shows the usage of the zendesk.eventFlow API:

lifecycleScope.launch {
    zendesk.eventFlow.collect { zendeskEvent -> 
        when (zendeskEvent) {
            is ZendeskEvent.UnreadMessageCountChanged -> // Your custom action
            else -> Unit
        }
    }
}

Authentication

The Zendesk SDK allows authentication of end users so that their identity can be verified by agents using Zendesk. A detailed article on the steps to set up authentication for your account is here. The steps mentioned in this article should be completed before beginning the steps below.

LoginUser

To authenticate a user call the loginUser API with your own JWT.

The JWT can contain the following fields:

Name	Type	Comment
external_id	String	The external id of the user. Required.
name	String	The name of the user. Optional.
email	String	The email of the user. Optional.

Kotlin

Zendesk.instance.loginUser(jwt = "your_jwt_here",
    successCallback = { user -> },
    failureCallback = { error -> }
)

Java

Zendesk.getInstance().loginUser("your_jwt_here", new SuccessCallback<ZendeskUser>() {
    @Override
    public void onSuccess(ZendeskUser value) {
    }
}, new FailureCallback<Throwable>() {
    @Override
    public void onFailure(@NonNull Throwable error) {
        
    }
});

LogoutUser

To unauthenticate a user call the logoutUser API.

This is primarily for authenticated users but calling logoutUser for an unauthenticated user will clear all of their data, including their conversation history. Please note that there is no way for us to recover this data, so only use this for testing purposes. The next time the unauthenticated user enters the conversation screen a new user and conversation will be created for them.

Kotlin

Zendesk.instance.logoutUser(
    successCallback = { },
    failureCallback = { error -> }
)

Java

Zendesk.getInstance().logoutUser(new SuccessCallback<Unit>() {
    @Override
    public void onSuccess(Unit value) {
        
    }
}, new FailureCallback<Throwable>() {
    @Override
    public void onFailure(@NonNull Throwable error) {
    }
});

Authentication Errors

All authentication errors can be observed through Events.

The most common error that will happen here is a HTTP 401 error. In this case a new JWT should be generated and a call made to loginUser.

Visitor Path

The Visitor Path lets agents see what screen the end user had landed on, for better conversation context.

Page View Event

The PageView object encapsulates information related to a user’s interactions and passes it to the Page View Event API. These session-based page view events can be seen in Agent Workspace by support agents using Zendesk.

Kotlin

Below is a code sample showing how to send a Page View Event.

The API accepts a PageView object as a parameter. Pass the location of the screen that the end user is on to url and the name of the screen to pageTitle.

// Create a `PageView` object
val pageView = PageView(url = url, pageTitle = pageTitle)
Zendesk.instance.sendPageViewEvent(pageView) {
    // Your custom result handling...
}, { error ->
    // Your error handling
},

Java

Below is a code sample showing how to send a Page View Event.

The API accepts a PageView object as a parameter. Pass the location of the screen that the end user is on to url and the name of the screen to pageTitle.

PageView pageView = new PageView(url, pageTitle);
Zendesk.getInstance().sendPageViewEvent(pageView, new SuccessCallback<Unit>() {
    @Override
    public void onSuccess(Unit value) {
        
    }
}, new FailureCallback<Throwable>() {
    @Override
    public void onFailure(@NonNull Throwable error) {
    }
});
