# Official Account

## Overview

A LINE Official Account (OA) is used as a communication channel for Unifi Apps—for announcements, onboarding, marketing campaigns, and customer support.

For detailed instructions on creating an OA, refer to:

[Create an Account | LINE for Business >](https://www.linebiz.com/jp-en/other/)

## **Types of LINE Official Accounts**

### **Unverified OA (Recommended)**

* No approval required from LINE’s local legal entity
* Immediately usable and easy to integrate with Unifi Apps
* Recommended for all Unifi Apps onboarding cases

### **Verified OA**

* Requires approval from LINE local entities in **Japan, Thailand, or Taiwan**
* Approval process could take a long time (often 3+ months)
* Not recommended unless legally required

## OA Profile (Required)

The profile (name, icon, description) should follow the same style and branding as the Unifi Apps.

### Welcome Message&#x20;

#### Text

* **Default Language:** English\
  (Since OA is globally accessible, English is required as the default language.)
* **Optional Languages:** Japanese, Thai, Chinese
* It is acceptable to include multiple languages within a single welcome message.

#### Rich Message

* Rich messages may include **images or videos** with descriptive text.
* A **CTA URL** is required (e.g., Unifi Apps URL).

### Rich Menu Setup

> Location: LINE Official Account > Home > Chat screen > Rich menus > Menu content setting

#### **Language**

* Default: **English**

#### **Template Guidelines**

The following structure is optimized to increase user conversion into the Unifi Apps:

<table><thead><tr><th width="205.40631103515625">Section</th><th>Description</th></tr></thead><tbody><tr><td>A</td><td>LINE MINI App URL or LINE Login LIFF URL for Unifi Apps</td></tr><tr><td>B &#x26; C</td><td><ul><li><strong>If section A contains the LINE MINI App URL, insert the LINE Login LIFF URL in section B.</strong></li><li><strong>For all other sections, insert URLs for social media, the website, or related channels.</strong></li></ul></td></tr><tr><td>D</td><td><ul><li><p>Unifi URL</p><ul><li>Image: Unifi Icon + Unifi Wordmark (Unifi_Logo_Primary Image)</li><li>URL: <a href="https://liff.line.me/2006533014-8gD06D64">https://liff.line.me/2006533014-8gD06D64</a></li></ul></li></ul></td></tr></tbody></table>
