How to set up social connection with LINE


Adding social connection with LINE to your app with Clerk is done in a few steps - you only need to set the Client ID, Client Secret and Authorized redirect URI in your instance settings.

To make the development flow as smooth as possible, Clerk uses preconfigured shared OAuth credentials and redirect URIs for development instances - no other configuration is needed.

Clerk preconfigured shared OAuth credentials are using Japan as the LINE region

For production instances, you will need to generate your own Client ID and Client secret using your LINE account.

The purpose of this guide is to help you create a LINE account and a LINE OAuth app - if you're looking for step-by-step instructions using Clerk to add social connection (OAuth) to your application, follow the Social connection (OAuth) guide.

Before you start

  • You need to create a Clerk Application in your Clerk Dashboard. For more information, check out our Set up your application guide.
  • You need to have a LINE developer account. To create one, click here.

Configuring LINE social connection

First, you need to create a new provider. Fill in a name and click Create.

Creating a new provider

The next step is to create a new LINE Login channel. You will have to select the provider you created before, the region to provide your LINE service, a channel name, and description and finally select Web app as the App type.

In the next screen, after the app has been created, you will find the Basic settings of the application. If you want to also make email address available for your application, you will have to apply for Email address permission in the bottom of your app's Basic settings.

You also need to add the OAuth Redirect URLs. Go to the Social Connections page of your Clerk Dashboard and enable LINE. In the modal that opened, ensure Use custom credentials is enabled and copy Authorized redirect URI. Paste the value into the LINE login → Callback URL input.

Once all the above are complete, copy the Channel ID and Channel secret. Go back to the Clerk Dashboard and paste them into the respective fields.

Pasting value into LINE dashboard

Don't forget to click Apply in the Clerk dashboard. Congratulations! Social connection with LINE is now configured for your instance.
