Application

This document guides information for the application("app").

Basic information

The basic information contains the app name, icon, and company name (business, corporation, or organization name). The basic information can be modified on [My Application] > [General] > [Basic information] > [Modify].

The app's basic information is presented on the consent screen for Kakao Login, the connected services page, the bottom of the Kakao Talk messages, and is required for Verify business information. To let users recognize the service correctly, register the app's basic information as the same as the actual service.

App key

The app keys are needed for the authorization of Kakao API requests. To check the app keys, go to [My Application] > [App Keys].

The app keys are issued by the platform. If an app key is used on the wrong platform, an error response is returned.

• Native app key: Used to initialize the Kakao SDK for Android or initialize the Kakao SDK for iOS.
• REST API key: Used to call APIs using a REST API.
  Pass this key in the HTTP request header when you send a request in a server environment.
• JavaScript key: Used to initialize the Kakao SDK for JavaScript SDK.
• Admin key: Used to call the APIs intended for administrators using a REST API. Be sure that your app’s Admin key does not get exposed because this key has all permissions.

Reissue

If one of the app keys is revealed, the OWNER can reissue the app keys. Make sure that the reissue is irreversible. After the reissue, the app keys in the service app or website must be changed to the reissued value.

Platform

Kakao APIs are only allowed to the services that registered platform information. To register platform information, go to [My Application] > [Platform].

Note: Error due to incorrect platform information

• iOS: Check if the registered [Bundle ID] is the same as the value of the [Project] > [TARGETS] > [General] > [Identity] > [Bundle Identifier].
• Web: Check if the site domain used to call the Kakao API is registered.
