Common questions about managing a LINE Official Account — connections, settings, and how Folders work — are answered below.
Can I manage multiple LINE Official Accounts in a single Workspace?
You can connect and manage multiple LINE Official Accounts in a single Workspace, though the maximum number you can connect depends on your plan.
The LINE Official Account list screen shows your connected accounts as cards. Each card displays the following metrics.
| Item | Description |
|---|---|
| Target reach | The number of friends you can deliver messages to |
| Messages sent this month | The heading for the two rows below. Each row reads "messages sent this month / limit" |
| LINE Official Account | "Messages sent this month as tallied by LINE / the LINE Official Account's limit". Messages sent from LINE Official Account Manager or other tools are included, and it updates every hour. When the LINE-side numbers can't be fetched, "Unavailable" is shown |
| Lumo | "Messages sent through Lumo this month / your plan's free allowance" |
When 20% or less of the LINE limit is left, the sent count turns amber. When the limit is reached, it turns red and the "LINE limit reached — sending paused" badge appears. On the Free plan and in test environments, the Lumo allowance works the same way, and the "Lumo limit reached — sending paused" badge appears once it is used up. On paid plans, messages beyond the Lumo allowance are billed as additional messages and sending does not stop (the sent count turns amber).
Clicking the "Messages sent this month" heading row takes you to the "Usage & Billing" screen. Clicking anywhere else on the card takes you to the Friends list screen for that account. To connect a new one, open the connection wizard from the "Connect LINE Official Account" button on the list screen.
On the Free plan, you can connect only one LINE Official Account. If you want to connect more than one, you will need to upgrade your plan.
What if a card shows "Connection error"?
"Connection error" means LINE is rejecting the channel authentication, so sending and syncing for that account are paused.
A banner also appears at the top of the screen, saying that LINE API calls are paused because of a LINE channel authentication error. Click "Open account settings" in the banner to go to the settings screen, where a "LINE channel authentication error" notice appears in the Messaging API section.
To resolve it:
- Check the account status (such as suspension) in LINE Official Account Manager
- On the settings screen, re-enter the Messaging API channel ID and channel secret and save. Saving verifies them again right away
- Lumo also re-checks automatically every hour, so once the account recovers on the LINE side, everything resumes within an hour
Broadcasts fail because a limit was reached
When the LINE Official Account reaches its monthly message limit, broadcasts for that month fail regardless of your Lumo plan.
When the limit is reached, admins receive an in-app notification titled "LINE message limit reached". The broadcast details also show a warning with the number of undelivered messages, and test sends show "The LINE Official Account has reached its monthly message limit".
To resolve it, change the plan or purchase additional messages in LINE Official Account Manager. The limit resets the following month. For recurring broadcasts, the broadcast itself stays scheduled and only that run fails.
Note that this is the LINE Official Account plan's limit — it's separate from your Lumo plan's free message allowance.
What happens if I disconnect a LINE Official Account?
When you disconnect, all LINE-related features stop, including sending and receiving messages and the automatic syncing of friends.
Disconnecting doesn't delete your data right away, but while disconnected you can't add friends or send broadcasts. If there is data you need, export it before you disconnect. If you connect the same LINE Official Account again, you can resume broadcasting and management.
You disconnect from that account's "Settings" screen. Selecting "Delete" in the confirmation dialog disconnects the account.
I changed a setting but can't find the save button
When you change a value on a settings screen, a save bar appears automatically at the bottom of the screen.
This bar has a "Save" button and a "Cancel" button. If you try to move to another page without saving your changes, a dialog appears letting you know that you have unsaved changes. To avoid losing changes unintentionally, choose whether to save before you move away.
Where can I check the Webhook URL?
You can check the Webhook URL in the "Set Webhook URL" step of the LINE Official Account connection wizard.
As you progress through the connection wizard, the Webhook URL is displayed and you can copy it with "Copy URL". Paste the copied URL into the Webhook URL field on LINE's settings screen. For details on the connection steps, see the article on connecting a LINE Official Account.
What happens to the contents of a Folder when I delete it?
When you delete a Folder, the contents inside the Folder are deleted along with it.
When you delete a Folder for Rich Menus, Segments, QR Codes, and the like, all of the contents inside it are deleted at the same time. Deleted Folders and their contents cannot be restored, so be sure to check what is inside before you delete one.
Note that what gets deleted here is strictly the Folder and the contents inside it. The "tag" you apply to friends and the "Segment" you use to narrow down friends are separate concepts and are handled differently from deleting a Folder.
Which features can I organize with Folders?
You can create Folders to organize Segments, Rich Menus, and QR Codes together.
On the list screen for each feature, create a Folder from "Create Folder", then select items and group them with "Move to Folder". When the number of items grows, dividing them into Folders by purpose or by campaign makes them easier to find.
