New permission to get users' email address released

Now you can request users who log in using LINE Login to grant your app the permission to get their email address. To do so, you first need to apply for the permission in the console.

For more information, see the sections below in Integrating LINE Login with your web app.

LINE Login v1 to be discontinued

Note: This notice only applies to LINE Login v1 users. These changes do not apply if you are using the latest v2.1 or v2 endpoints.

Starting from March 31, 2018 we will start terminating LINE Login V1 endpoints. Please see the following schedule on the termination date for each endpoint. After an endpoint is terminated, any access to it will result in a 4XX status code as a response.

# Endpoints terminating on March 31, 2018
  • Issue access token: https://api.line.me/v1/oauth/accessToken
# Endpoints terminating on April 30, 2018
  • Get user profile: https://api.line.me/v1/profile
  • Logout: https://api.line.me/v1/oauth/logout
# Endpoints terminating on June 30, 2018
  • Verify access token: https://api.line.me/v1/oauth/verify
  • API endpoints for the LINE SDK for iOS and Android version 3.x or earlier

To avoid any issue related to the termination of LINE Login V1, please make sure to update your service to the latest LINE Login version. Please see the following page for more details on the latest LINE Login version.

Social API overview

Please also notice that the LINE user identifier is different between LINE Login V1 and LINE Login V2 or higher. If you are using the V1 user identifier on your service, you will need to convert the user identifier to use the latest LINE Login version. Please see the following page for more details on how to convert the LINE user identifier.

Converting an MID to a user ID

If you are a partner, we will contact you individually for more details.

New article on converting an MID to a user ID

Users are identified using a user ID in LINE Login v2 or later instead of an MID in v1. If you have integrated LINE Login v1 into your app and want to migrate it to v2 or later, you need to convert MIDs to user IDs.

For more information, see Converting an MID to a user ID.

Property for accessibility released

Now you can specify text to be spoken using the label property for imagemap messages and rich menus when the accessibility feature is enabled on the client device. This feature is supported on LINE 8.2.0 and later for iOS.

For more information, see the updated reference documentation below.

Introducing the Community site for developers

We are excited to introduce our new Community site added to the LINE Developers site.

Community site

You can find knowledge and examples from our developer community on the Community site, including expert tips from third-party developers and information about how to create attractive applications using the LINE APIs. Currently, the site has a Bot Directory, a showcase of chatbots available on LINE, and a Q&A section for development techniques.

Bot Directory and Q&A

New properties for template messages and postback actions released

# Default actions can now be set for template messages

The defaultAction property has been added to the column object for buttons and carousel template messages. As a result, you can indicate a single action to be executed when a user taps anywhere in the image, title, or text area.

For more information, see the updated reference documentation below.

# displayText property for postback actions released

We have released the displayText property and have deprecated the text property for postback actions. We recommend using displayText instead of the text property. Note that the dislayText and text properties cannot both be used at the same time.

For more information, see the Postback action reference documentation.

LINE SDK for Android 4.0.7 released

The LINE SDK for Android version 4.0.7 has been released. You can download the SDK from the following page.


  • Fixed a crash that occurs if the user exits LINE using the home button and then opens the SDK app before LINE finishes the authentication process.

We will continue to provide improvements so that you can code more easily.

Let us announce the LINE API experts of the first quarter of 2018

LINE API Expert is a program that recognizes skilled engineers who have a deep understanding of the APIs provided by LINE and are influential in the community by giving them the title of "LINE API experts". In addition to providing an array of benefits, LINE will also support the various activities of these LINE API experts through this program.

The LINE API expert program was introduced at the LINE DEVELOPER DAY, September last year and a lot of engineers have applied through the LINE Developers site. Our internal review committee reviewed each item with a strict standard and came up with the final result. Please check the detail on the Expert List page or LINE Engineering Blog.

We look forward to see the selected members to actively engage in the developer community through meetups, online forum, SNS or blogs, and other means. LINE will be opened to the range of activities and will support their moves with all means.

For the Q1, a total of 22 qualified engineers have been selected from four Asia countries, including Japan.
