Properties let you save and manage the information you need for each friend as custom fields. Give friends the information your marketing needs — such as job title, membership rank, or number of visits — and use it to narrow down segments and branch workflows. This article explains how to create properties and put them to use.
What Are Properties
A property is a custom field tied to each individual friend. In addition to the basic information available from LINE, such as the display name, you can freely define the information you want to manage yourself.
Whereas a tag is a marker for whether it is "attached or not," a property can hold a value like "Job title = Manager" or "Visits = 5." Properties suit cases where you want to manage friends in detail by the kind or level of a value; tags suit simple classification.
In addition to the built-in properties provided in advance, you can create your own custom properties. Built-in properties cannot have their type or key changed, and cannot be deleted.
Open the Properties Screen
The Properties management screen is in the side menu of your LINE Official Account.
- Open the target LINE Official Account
- Click Properties in the side menu
- The list of properties appears
Create a Property
Use Create Property to define a new custom property.
| Setting | Details |
|---|---|
| Label | The name shown on screen (e.g. Job Title) |
| Key | The system identifier. Enter it in snake_case starting with a lowercase letter (e.g. job_title). It cannot be changed after creation |
| Type | The kind of value. Choose from Text, Number, Date, Email, Phone, Select, or Status |
| Options | For the Select and Status types, defines the selectable values. For Status, the order from top represents the progression of stages |
| Display order | Lower numbers appear first |
A property's account cannot be changed after creation. Set Localized names to show the name in each member's language.
Turning on Show in Friends list by default shows a column for that property in every member's Friends list (each member can still hide it individually).
Set Property Values
Property values can be set by automatic updates from a workflow and by data import.
- Automatic updates from a workflow: The workflow action Set Property automatically updates a friend's property. You can automate operations like "increase the number of visits for friends who used a coupon"
- Bulk setting by data import: Import a CSV to set and update the values of many friends at once
Identity Properties and Data Import
A property with Use as identity property turned on becomes the key for matching friends during a CSV import (for example, identifying and updating a friend by membership ID).
You can choose, per property, how a repeated import behaves under Data import behavior.
| Behavior | Details |
|---|---|
| Update on re-import (last write wins) | Overwrites the value on every import |
| Keep existing — log conflict | Keeps the value if one already exists, and records the difference |
| Manual only — imports skip this | Not updated by import (identity properties are locked to this behavior) |
Put Properties to Use
The values you set can be used to narrow down friends and as conditions for automation.
| Where used | Details |
|---|---|
| Friends list | Choose which columns to show and their order with the property columns, and check the values in the list |
| Inbox | Check the current friend's values in the Properties card on the right-hand panel of the conversation |
| Segment | Choose Lumo Property as a condition, and narrow down the delivery target by value |
| Workflow | The Set Property action updates values automatically |
Where this property is used, on the property's edit screen, shows which segments and workflows it is used in. Check the scope of impact before deleting a property that is in use.
Organize with Folders
Once you have many properties, you can organize them with folders.
- Create a folder with New folder
- Select properties and organize them with Move to folder
- Even if you delete a folder, the properties inside are not deleted — they move to the top level
If Something Goes Wrong
When a property does not behave as expected, check the key, type, and where it is used.
- You want to change the key: The key cannot be changed after creation. Create a new property and migrate the values
- You want to delete a built-in property: Built-in properties cannot be deleted. If you do not need one, remove it from the Friends list display instead
- Values are not updated by import: Check that the property's Data import behavior is not set to "Manual only" or "Keep existing"
- Cannot delete, or worried about impact: Check the usage in segments and workflows under Where this property is used on the edit screen before deleting
