This document describes how to integrate Kakao Talk Channel APIs into your service with the Kakao SDK for Android (hereinafter referred to as 'Android SDK').

Before you begin

Register Android Platform

To use the Android SDK, you must register the Android platform in advance. Go to [My Application] > [Platform] and register the Android platform by specifying its package name and key hashes. If not, an error may occur.

Add modules

To use the features of Kakao Talk Channel, you need to add v2-talk (Kakao Talk module) that provides TalkApiClient in the module-level build.gradle file by referring to Add modules. Because the ReactiveX Android SDK does not provide the Kakao Talk Channel API, you must use the Kakao Talk module that the Android SDK provides.

To use the Checking Kakao Talk Channel relationship API that requires Kakao Login, you must also add the Kakao Login module, v2-user. Implement Kakao Login beforehand. After that, call this API with the access token issued after a user logs in.

Add Kakao Talk Channel

To enable a user to add a specific Kakao Talk Channel as a friend, call the addChannelUrl() method defined in the TalkApiClient class. You must pass the Kakao Talk Channel ID through channelPublicId as an argument.

You can invoke the bridge page URL using the openWithDefault() method in KakaoCustomTabsClient.

This API does not force users to add Kakao Talk Channels but only presents the bridge page to redirect users to Kakao Talk Channel specified with the value of channelPublicId. When this feature is invoked, users can select whether to add the Kakao Talk Channel on the bridge page.

Parameter

// Add URL of Kakao Talk Channel.
val url = TalkApiClient.instance.addChannelUrl("_ABcdE")

// Open through CustomTabs.
KakaoCustomTabsClient.openWithDefault(context, url)

When the user selects the option to add the Kakao Talk Channel on the bridge page, the Kakao Talk app starts through a Custom URL Scheme, and the designated screen of the Kakao Talk Channel is displayed.

This API does not inform you whether the user adds the Kakao Talk Channel. To check the added status, use the Checking Kakao Talk Channel relationship API that shows the relationship between a user and a Kakao Talk Channel.

Start Kakao Talk Channel chat

To allow a user to start a Kakao Talk Channel chat, call the channelChatUrl() method defined in the TalkApiClient class. You must pass the Kakao Talk Channel ID through channelPublicId as an argument.

You can invoke the bridge page URL using the openWithDefault() method in KakaoCustomTabsClient.

Parameter

// Kakao Talk Channel chat URL
val url = TalkApiClient.instance.channelChatUrl("_ABcdE")

// Open through CustomTabs.
KakaoCustomTabsClient.openWithDefault(context, url)

When the user selects the option to start a Kakao Talk Channel chat on the bridge page, the Kakao Talk app starts through a Custom URL Scheme, and the designated screen of the Kakao Talk Channel is displayed.

When the bridge page is invoked, the Kakao Talk Channel sends the user a message saying "Hello, how can I help you?" with the web page URL that the user requested a chat for.

Check Kakao Talk Channel relationship Login required Consent required

To use this API,

• Set the Kakao Talk Channel addition status and details scope to 'Required consent' or 'Optional consent' in [My Application] > [Kakao Login] > [Consent items].
• A user must consent to the scope. Otherwise, an error occurs. In this case, you can request additional consent from the user.
• Add both v2-user (Kakao Login module) and v2-talk (Kakao Talk module) in the module-level build.gradle file. Refer to Add modules and Before you begin.

To check if a specific user has added or blocked your Kakao Talk Channel connected to your service app, call the channels() method defined in the TalkApiClient class.

Make sure that this API only informs the relationship between the user and the Kakao Talk Channel connected to the app that made a request. Thus, you cannot get all Kakao Talk Channels' information that the user has added but the channels related to your service only.

Sample

// Check Kakao Talk Channel relationship
TalkApiClient.instance.channels { relations, error ->
    if (error != null) {
        Log.e(TAG, "Failed to check channel relationship.", error)
    }
    else if (relations != null) {
        Log.i(TAG, "Succeeded in checking channel relationship. \n${relations.channels}")
    }
}

var disposables = CompositeDisposable()

// Check Kakao Talk Channel relationship
TalkApiClient.rx.channels()
    .retryWhen(
        // Request additional consent for InsufficientScope. 
        RxAuthOperations.instance.incrementalAuthorizationRequired(context)
    )
    .subscribeOn(Schedulers.io())
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe({ relations ->
        Log.i(TAG, "Succeeded in checking channel relationship. \n${relations.channels}")
    }, { error ->
        Log.e(TAG, "Failed to check channel relationship.", error)
    })
    .addTo(disposables)

Return data

If the request is successful, channels() returns the Channels object.

Legacy

It is highly recommended to migrate to the new version of Android SDK as soon as possible because the Legacy version may not be supported anymore.
