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.

We've added an article about the LINE URL scheme to our LINE Login and Messaging API documentation. You can use the URL schemes to help your users navigate to specific content such as the camera, location, or settings screens in the LINE app. The LINE URL scheme can be used in your bot (Messaging API) from within the LINE app or in your native or web apps to automatically open the LINE app.

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 the 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 the 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
  • iOS SDK
  • Android SDK
  • 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.

If you want to keep up-to-date with our latest developments, add the LINE Developers official account as a friend on LINE using the QR code or the button below.
