When your back-end server receives an ID token originating from LINE Login v2.1 or the LINE SDK, you should verify that the ID token is authentic.

Previously, you had to use a JWT library or write your own decoding and verification code.

After this release, you merely have to send an HTTP request to the verification endpoint to determine if an ID token is authentic.

For instructions on verifying ID tokens, read Transfer ID token to back-end server.

December 12th, 2019 marks the end-of-life date for LINE SDK v4.0 for Android and LINE SDK v4.1 for iOS (from hereon collectively called LINE SDK v4.x). On that date, we'll remove from this site the following things:

• Download link for LINE SDK v4.0 for Android
• Guides for LINE SDK v4.0 for Android
• Reference documentation for LINE SDK v4.0 for Android
• Download link for LINE SDK v4.1 for iOS
• Guides for LINE SDK v4.1 for iOS
• Reference documentation for LINE SDK v4.1 for iOS

Why we're doing this

To ensure a consistent, secure, up-to-date experience for LINE users, our partners' apps and services should use the latest version of our technology. We already marked LINE SDK v4.x as deprecated some time ago, but continued to offer documentation and download links as a courtesy to partners who couldn't upgrade on short notice. Now we're taking the next logical step: declaring LINE SDK v4.x end-of-life and removing all references from our site.

Upgrading to a new SDK version

What you need to do to upgrade depends on what version you're currently using.

From	To	Notes
LINE SDK v4.x for iOS Objective-C	LINE SDK v5.2 for iOS Swift	The old and new versions use different programming languages, which makes migrating a big task. We hope the migration instructions in Upgrading the SDK will make it easier.
LINE SDK v4.x for Android	LINE SDK v5.1 for Android	There are minor differences between the old and new version, particularly with relation to how login works. The page Integrating LINE Login with your Android app explains how to integrate the latest version.
LINE SDK v3.x for iOS Objective-C	LINE SDK v5.2 for iOS Swift	There are major differences between the old and new version, meaning you'll have to redo your integration from scratch. See Integrating LINE Login with your iOS app for instructions.
LINE SDK v3.x for Android	LINE SDK v5.1 for Android	There are major differences between the old and new version, meaning you'll have to redo your integration from scratch. See Integrating LINE Login with your Android app for instructions.

Changes

LINE Login v2.1 and Social API v2.1 are supported

You can set permissions to be granted to your app as scopes when users log in to your app with LINE Login. By setting scopes, you can get ID tokens when you get access tokens. Those tokens contain user information according to the scopes you set with the login request.

You can display an option to add your bot as a friend to users logging in to your app. You can get the friendship status between users and your bot with login responses and the Social API.
