Kakao Talk Message

Android

This document describes how to integrate Kakao Talk Message APIs into your service with the Kakao SDK for Android ("Android SDK").

The Kakao Talk Message API only supports sending messages between users within the same service, and the Kakao Talk Social API permission is required to provide the message sending feature to friends. For more details, see Message sending features and How to use.

Before you begin

Choose implementation method

1. Select message sending feature

Kakao Developers provides two types of message sending features: Kakao Talk Share and Kakao Talk Message. Refer to Message sending features to select the feature to use. If you want to use Kakao Talk Message, perform the following steps.

2. Select message type and configuration method

Refer to Template types to decide which message template to use.

Refer to Configuration method comparison to decide how to configure messages. You can use default templates based on predefined templates in object form, or custom templates configured directly for your service.

3. Select message target

Note that for Kakao Talk Message, the APIs used are distinguished according to the message targets.

Target	Description
Send to me	Sends a message to the "Me" chat in Kakao Talk of the currently logged-in user. This feature cannot send messages to other users and can only send messages to the logged-in user themselves.
Send to friends	Sends a message to friends in Kakao Talk of the currently logged-in user. Important: Additional feature request is required. You must implement a process to receive recipient information through Retrieve friends through picker API or Retrieve friends through picker API. You can send messages to up to 5 friends at once. Daily and monthly quotas are set, so refer to Quota.

Note: Permission Required

If you want to send messages to friends, you must request permission. See Usage policy.

Set Custom URL Scheme

Kakao Talk messages include links that execute specified web pages or apps. Buttons in messages execute apps using Custom URL Scheme (Custom URL Scheme) composed of URI schemes and parameters.

To allow users to execute your app using buttons in Kakao Talk messages, you must configure custom URL scheme settings in the AndroidManifest.xml file. For detailed setup instructions, see Custom URL scheme configuration.

Send me message with default template

Basic information

Reference	App setting
[SDK, RxSDK] `sendDefaultMemo()` [SDK] `DefaultTemplate` [SDK] `MessageSendResult` [SDK] `MessageFailureInfo`	Install Initialize Set Custom URL Scheme

Permission	Prerequisite	Kakao Login	User consent
-	Register platforms Activate Kakao Login Manage consent items	Required	Required: Send message in Kakao Talk (talk_message)

This is an API that sends a message to me by defining components as objects according to predefined template formats. For detailed message configuration methods, see Default template.

Request

To create a message, implement the DefaultTemplate interface, then use one of the following classes according to the desired template type to configure template objects.

Feed template: FeedTemplate
List template: ListTemplate
Location template: LocationTemplate
Commerce template: CommerceTemplate
Text template: TextTemplate
Calendar template: CalendarTemplate

When calling sendDefaultMemo(), pass the template object as the template parameter.

Response

When message transmission fails, it returns a response code. See Error code to identify the cause of failure with code and msg.

Example

Kotlin

RxKotlin

TalkApiClient.instance.sendDefaultMemo(defaultFeed) { error ->
    if (error != null) {
        Log.e(TAG, "Failed to send me a message.", error)
    } else {
        Log.i(TAG, "Succeeded in sending me a message.")
    }
}

var disposables = CompositeDisposable()

TalkApiClient.rx.sendDefaultMemo(defaultFeed)
    .retryWhen(
        // Retry the request to send a message after requesting additional consent to resolve the InsufficientScope error.
        RxAuthOperations.instance.incrementalAuthorizationRequired(context)
    )
    .subscribeOn(Schedulers.io())
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe({
        Log.i(TAG, "Succeeded in sending me a message.")
    }, { error ->
        Log.e(TAG, "Failed to send me a message.", error)
    })
    .addTo(disposables)

Send me message with custom template

Basic information

Reference	App setting
[SDK, RxSDK] `sendCustomMemo()` [SDK] `MessageSendResult` [SDK] `MessageFailureInfo`	Install Initialize Set Custom URL Scheme

Permission	Prerequisite	Kakao Login	User consent
-	Register platforms Activate Kakao Login Manage consent items Message template	Required	Required: Send message in Kakao Talk (talk_message)

This is an API that sends messages using custom templates directly configured in [Tools] > [Message Template]. For message configuration methods, see Custom template.

Request

When calling sendCustomMemo(), you must pass the template ID confirmed in the message template tool as the templateId parameter.

To include variable information in messages, add user arguments to the corresponding custom template, then pass keys and values as the templateArgs parameter. If you do not use this parameter even though the custom template includes user arguments, the part specified as user arguments will be exposed in the message as ${KEY} format.

Response

When message transmission fails, it returns a response code. See Error code to identify the cause of failure with code and msg.

Example

Kotlin

RxKotlin

// Template ID of the custom template.
//  * Refer to the guide: https://developers.kakao.com/docs/latest/en/message-template/custom
val templateId = templateIds["customMessage"] as Long

TalkApiClient.instance.sendCustomMemo(templateId) { error ->
