What is a QR Code?
A QR Code is a feature that generates a QR Code and a short URL for adding Friends so you can track where your friends come from. When a customer scans or clicks the link to add you as a friend, the scan is counted, so you can see which channel your friends came from. A scan can also automatically send a message or start a Workflow.
To use QR Codes, you need to connect your LINE Official Account and also set up LINE Login. If the setup is not complete, a message will appear on the screen letting you know.
What you can do with QR Codes
QR Codes let you see which channels are bringing in friends while automating everything right up to the response after a friend is added. The main things you can do are as follows.
- Generate a QR Code for adding Friends, along with a short URL that measures scan counts
- Send text or an Auto Send Message to friends who scan the code
- Start a Workflow triggered by a scan
- Record the inflow source and URL parameters to analyze acquisition channels
- Automatically update linked HubSpot contacts' properties when the code is scanned
- Link with Shopify, HubSpot, and Klaviyo IDs
- Organize and manage codes with Folders
Just tell the agent your goal, and you can consult on designing QR Codes for your campaign and analyzing inflow all in one place. If you would rather configure everything yourself in detail, refer to the QR Code components and create one from the edit screen.
While HubSpot is connected, the name of the QR Code that prompted the friend add is recorded on the HubSpot contact's "LINE Traffic Source" property. It is recorded only the first time. HubSpot reports can show you which QR Code brought each friend in, too.
How it looks on a phone and on a computer
A short URL looks different depending on the device it is opened on. Either way, the person gets all the way to adding you as a friend.
- Phone: Opening the short URL takes them straight to adding you as a friend
- Computer: A landing page appears with your LINE Official Account's name and a QR Code. Scanning that QR Code with a phone takes them on to adding you as a friend
That means no one hits a dead end when they open your short URL on a computer, even when you put it in an email or on a website. The landing page also lets them copy the link, so they can send it to their phone and carry on from there.
When someone opens a disabled QR Code, a landing page appears on any device with your LINE Official Account's name and the message "This QR code is currently unavailable" — it doesn't turn into an error screen.
QR Code list screen
The QR Code list screen lets you view all the QR Codes you have created and manage them together. Use "Create QR Code" at the top right of the screen to create a new QR Code.
| Item | Description |
|---|---|
| Name | The management name for the QR Code. Click it to open the edit screen |
| QR Code | A preview of the QR Code image |
| Scan count | The number of times the QR Code has been scanned |
| URL | The automatically generated short URL |
| Last updated | The date and time it was last updated |
You can create Folders to organize your QR Codes. You can select multiple QR Codes to move them to a Folder or delete them in bulk, and you can filter by searching with free text. The list contents can be downloaded as CSV.
QR Code components
The QR Code edit screen is made up of the response content, ID linking, options, and output sections. Along with these, you set the QR Code's name and usage status.
Name and usage status
| Item | Description |
|---|---|
| Name | The management name used to identify the QR Code |
| Usage status | Select "Enable" or "Disable" |
Response content
In response content, you set the message that is automatically sent to friends who scan the QR Code.
| Response type | Description |
|---|---|
| Text | Sends the text message you set to the chat |
| Auto Send Message | Sends an Auto Send Message you created in advance |
| No response | Doesn't send a response message. Choose this when you only want measurement or tagging |
ID Linking
In ID linking, you can link people who become friends via the QR Code to customer information in external services. Shopify, HubSpot, and Klaviyo are supported.
| Integration type | Information to link |
|---|---|
| Shopify | Shopify customer ID |
| HubSpot | HubSpot contact information |
| Klaviyo | Klaviyo profile (matched by email address) |
The linking URL appears after you save the settings. Save the settings first, then open this screen again to check the URL.
The linking URL's format and usage differ by integration.
- Shopify: Your store's URL (
https://your-store-domain/apps/lumo/q/…) appears. Link to this URL from your Shopify theme or pages, and logged-in customers add the friend and link their ID at the same time. Logged-out visitors only add the friend - HubSpot: Add
?c={{ contact.hs_object_id }}to the short URL and set it as a link inside your HubSpot emails - Klaviyo: Add
?e={{ person.email|urlencode }}to the short URL and set it as a link inside your Klaviyo emails
Options
In options, you set inflow analysis, friend information updates, and the behavior after a scan.
| Item | Description |
|---|---|
| Category | Classify the QR Code's purpose from "Store," "Event," "Ad," "Web," "Email," "Social," or "Other" |
| Inflow source | Records where the QR Code is placed (Instagram, X, Facebook, website, etc.) |
| URL parameter | Adds a query parameter to the short URL so it can be measured with an external analytics tool |
| Property update | Automatically updates the specified properties of the linked HubSpot contact when the code is scanned |
| Redirect URL | Specifies the URL to navigate to after a scan. If not set, it navigates to the LINE add-friend screen |
| Workflow | Selects the Workflow to run, triggered by a scan |
When you point the redirect URL at your own site, the friend's LINE user ID is added to the destination automatically as a lineid parameter. Pick it up in a hidden field on your own form and you can tie form submissions to LINE friends.
Make the redirect destination an HTTPS URL, and take care not to leave the lineid you receive in logs and the like. Do not use it for authentication — it is only a value for tying friends together.
Output
In output, you check the short URL and QR Code image generated after saving.
When you save a QR Code, a short URL and a QR Code image are automatically generated. You can copy the URL, and you can download the QR Code image to use on print materials or the web.
Common usage patterns
Creating a separate QR Code for each placement makes inflow analysis easier. Here are some typical ways to use them.
- Adding friends in-store: Place a QR Code in your store to guide visiting customers to become friends. Set the category to "Store" and record the inflow source
- Measuring ad performance: Create a QR Code for each ad medium and compare which medium brings in the most inflow
- Adding friends from business cards: Print a QR Code on your business card to measure friend additions from meetings and sales activities
- Integrating with your e-commerce site: Integrate with Shopify, HubSpot, and Klaviyo to automatically link the IDs of people who become friends via the QR Code
