LINE Official Account Settings

The settings screen is where you review and update a connected LINE Official Account's basic information, Messaging API, LINE Login, and more. You can leave day-to-day operations to the agent, but some settings — such as updating account information or removing a connection — can only be done here.

Opening the settings screen

You can open the settings screen for a LINE Official Account by selecting the target account under "Accounts" in the left menu and opening "Settings" in the side menu.

1. Select the target LINE Official Account
2. Click "Settings" in the side menu

A navigation panel appears on the right side of the settings screen, letting you jump quickly to each section.

Basic Information

You can review and update the account's basic information, such as its display name and description in Lumo.

While a paid plan (including a trial) is active, you can't change the country / region of the LINE Official Account. If you need to change it, contact support.

After making changes, click "Save" to apply them. To discard your changes, click "Cancel".

Messaging API

You can manage the Messaging API settings required to connect to your LINE Official Account.

You can find the channel ID and channel secret in the Messaging API settings of the LINE Official Account you are connecting from.

The connection status ("Working" / "Needs attention") appears to the right of the heading, and the "Connection check" panel at the bottom of the card shows what was checked and how to fix it, row by row. See "Checking the connection status" for details.

LINE Login

You can manage the LINE Login settings required to use ID integration with external services (such as Shopify or HubSpot) and the QR Code feature.

If you enter either the channel ID or the channel secret, the other becomes required as well. The LIFF URL must begin with https://liff.line.me/.

The callback URL and the LIFF endpoint URL are shown before you save the channel ID and secret, so you can register them in LINE Developers and create the LIFF app first, then save everything at once.

In addition, set the connected LINE Official Account in the "Linked LINE Official Account" field of the LINE Login channel in the LINE Developers console. With this setting, users who log in via a QR code see the add-friend screen and can finish adding the account as a friend within the login flow, so you won't miss out on new friends. We recommend setting this up.

About the URLs shown here

The callback URL and the LIFF endpoint URL begin with https://i.lmt.cx/. It's a neutral domain with no brand name, so the LINE Login screen doesn't show the dashboard's domain. If you set up LINE Login before September 2026, the previous URLs beginning with https://dashboard.lumo.cx/ are registered in LINE Developers. They keep working, so there's no rush to change them.

To move to the new URLs:

1. In LINE Developers, add the callback URL shown here to the "Callback URL" list of the LINE Login channel. You can leave the previous URL in place
2. Reopen the Lumo settings screen. Once the registration is confirmed, logins switch to the new URL automatically. The "Callback URL" row of the "Connection check" panel shows the result
3. In LINE Developers, replace the "Endpoint URL" of the LIFF app with the LIFF endpoint URL shown here

Logins keep working whichever order you follow.

Checking the connection status

For the Messaging API and LINE Login cards, Lumo checks with LINE whether the settings are registered correctly and shows the result to the right of the heading. The check runs when you open the settings screen and after every save, and you can run it again anytime with "Check again".

The "Connection check" panel at the bottom of the card lists one row per item: the first line says what was checked, the second how to fix it. After fixing things in LINE Developers, click "Check again".

Once the callback URL registration is confirmed, logins automatically switch to the URL shown. The previous URL keeps working.

At the very bottom of each card you'll see who last saved the credentials and when — the first place to ask when it's unclear which account holds the provider or channel permissions.

Importing friends

You can import friends who are already on your LINE Official Account into Lumo all at once. Use this when you want to carry over your past friends right after connecting.

This is only available for verified accounts or premium accounts.

Steps to run an import

1. Click the "Import" button in the import section
2. Click "Start Import" in the confirmation dialog

The import status ("Not run yet" / "Processing" / "Completed" / "Error") appears to the right of the heading, and the "Import status" panel at the bottom of the card shows the result: progress for friends and profiles while a run is going, and the number imported plus the last run time once it's done. If some friends or profiles couldn't be brought in, the panel shows how many and what to do. See "How to import friends" for details.

Removing the account connection

This action disconnects your LINE Official Account from Lumo. When you remove the connection, all features related to the LINE connection — such as sending and receiving messages and automatic syncing — stop.

Steps to remove the connection

1. Click "Disconnect LINE Official Account" at the bottom of the settings screen
2. Click "Delete" in the confirmation dialog

Points to note before removing

• When you remove the connection, all features related to the LINE connection — such as sending and receiving messages and automatic syncing — stop
• If you have any data you need, export it before removing the connection
• If you want to connect again, you can reconnect the LINE Official Account from the account screen
