    LINE Login v2.1 released

    We have released LINE Login v2.1 which provides new features to make it easier for you to implement a login feature to your application. The new version adds support for the OpenID Connect 1.0 specification which is an identity layer on top of OAuth 2.0.

    Here are some of the key changes.

    ID tokens

    With LINE Login v2.1, you'll be able to get ID tokens which contain user profile information when you retrieve the access token. This means that you no longer need to send a separate request to retrieve a user's profile information.

    For more information, see ID tokens.

    Login sessions

    In version 2.1, when users are redirected to the authorization endpoint, we'll be able to check the login session to determine if the user is logged in to LINE or not. If users are logged in to LINE and their browsing session is valid, they will not be required to enter their email and passwords to log in.

    For more information, see Authentication and authorization process.

    Updated endpoints

    We have updated our authorization endpoints where you can use the new version 2.1 features. You can find more detailed information on the following pages.

    Note: You'll still be able to use our LINE Login v2 endpoints.

    Introducing the redesigned LINE Developers site

    We are excited to introduce our new, redesigned LINE Developers site. We hope that this update will improve the experience for developers, making it easier to use our products (such as LINE Login and Messaging API) and to find the documentation that you need. Here, we'll take you through some of the key changes to the site.

    LINE Developers console

    Console top

    The new and improved "LINE Developers console" makes it easier to create and manage your channels. You can login to the console to register a developer account, create a provider, and create channels for Messaging API and LINE Login.

    If you have created channels on the LINE Business Center (discontinued on September 21, 2017), you'll be able to see and manage the channels from the LINE Developers console. Note that "Enterprises" on the LINE Business Center are called "Providers" on the LINE Developers console.

    When creating a new Messaging API channel, you no longer need to go to the "Messaging API Settings" page of LINE@ Manager to enable API features and configure settings. Those settings are now available on the "Channel settings" page of the console. However, you will still need to use LINE@ Manager if you want to configure a rich menu and account page for your bot.

    For information on how to create new channels for LINE Login and Messaging API, see the links below.

    Homepage and product overviews

    We've overhauled our homepage and have made it easier to access the console, documentation, and news. We've also added product overview pages for LINE Login and Messaging API to the site.

    Documentation updates

    We have updated our documentation structure, integrated our API reference docs into the site, and revised our existing documentation.


    Our documentation is now organized into the categories listed below, each with their own sidebars. You can also easily browse the documentation available from the Documentation overview page.

    • LINE Login
    • Messaging API
    • LINE SDK for iOS
    • LINE SDK for Android
    • Social API

    In addition, you can find the links to the LINE Social Plugins and LINE Notify websites.

    Reference documentation

    Our API and SDK reference documentation has been updated and integrated into the site. The existing reference documentation at will no longer be updated and discontinued in around one month. For the latest reference information, please use the new pages below.

    New and updated documentation

    We have added various new articles for the Messaging API and have made updates to various other documents. Check out some of the new and updated articles below.

    Enterprise documentation

    Our existing enterprise-facing content (Business Connect, mission stickers, link messages) has been separated from our public-facing content. If you are a partner and require access to the enterprise documentation, please contact your LINE representative for information.


    We have a new frequently asked questions (FAQ) section where you can find answers to questions about LINE Login and Messaging API. Note that the questions from the line-bot-faq GitHub repository have been integrated into the FAQ section.


    We will continue to make improvements to the LINE Developers site and our developer documentation to make it easier for you to develop apps using our products.

    New template message features released

    We have released the following features for the Messaging API.

    Image carousel template

    The image carousel template lets you send multiple images in a single message that users can cycle through like a carousel. You can then set template actions for when an image is tapped.

    For more information, see the image carousel reference.

    Datetime picker action

    With the datetime picker template action, you can provide an easy way for users to pick a date and time without having to type it in manually. The datetime picker action can be used in any type of template message and returns a postback event when the action is tapped.

    Note: The datetime picker action is supported on LINE 7.9.0 and later for iOS and 7.12.0 and higher for Android.

    For more information, see the datetime picker action reference.
