Overview of Common Profile Quick-fill

What is Common Profile Quick-fill

Quick-fill is a feature that automatically fills in the necessary profile information by tapping the Auto-fill button on the LINE MINI App. You can easily use the Common Profile information that a user has set in the Account Center in the LINE MINI App.

By integrating Quick-fill into your LINE MINI App, users can automatically enter an address or phone number with a single tap. For example, when making a reservation at a restaurant or ordering from an online store, users can save themselves the hassle of entering the information manually.

This page explains how to integrate Quick-fill into your LINE MINI App.

For information on how to use Quick-fill on the LINE MINI App, see Set Common Profile to use Quick-fill (only available in Japanese) in the LINE user's guide.

Languages that support Quick-fill

Quick-fill currently supports Japanese only. Therefore, the Quick-fill screen will be displayed in Japanese regardless of the language setting in the LINE app.

How to integrate Quick-fill into the LINE MINI App

To integrate Quick-fill into the LINE MINI App, follow the steps below:

1. Apply to use Quick-fill
2. Specify the scope of Quick-fill in the LINE Developers Console
3. Submit a review request for your LINE MINI App
4. Develop your LINE MINI App

1. Apply to use Quick-fill

To use Common Profile Quick-fill, fill out the usage application form and submit it via the application form. If the same service provider is applying for multiple LINE MINI Apps at once, you can use the application form for multiple applications.

• [Single application] Usage application form (Excel file) (Only available in Japanese)
• [Multiple applications] Usage application form (Excel file) (Only available in Japanese)

After completing the usage application form, submit your application via the following form. We'll notify you via email regarding the receipt of your application and the results of the review.

Application form (Only available in Japanese)

2. Specify the scope of Quick-fill in the LINE Developers Console

After your application has been accepted, specify the scope of the information you want to use. In the LINE Developers Console, select the target LINE MINI App channel, and in the Scope section of the Web app settings tab, check the box for the scope you want to use.

For more information about the types of scope that you can use with Quick-fill, see Types of scope that can be selected in the LINE Developers Console.

3. Submit a review request for your LINE MINI App

Once you have specified the scope, request LINE MINI App review from the Review request tab on the LINE MINI App channel. Once the LINE MINI App has passed the review, you will be able to develop within the specified scope.

4. Develop your LINE MINI App

You can develop your LINE MINI App that integrates Quick-fill. For information on how to develop, see Integrate Quick-fill with the LIFF Plugin.

When developing a LINE MINI App that integrates Quick-fill, follow the instructions below:

• Common Profile Quick-fill design regulations
• LINE MINI App development guidelines
• LIFF app development guidelines
• LINE Login development guidelines

Integrate Quick-fill with the LIFF Plugin

To develop Quick-fill, you need to use the LIFF SDK and the LIFF plugin. For information about the LIFF SDK version that the LIFF plugin works with, see LIFF SDK version.

You can integrate the LIFF SDK into your LINE MINI App in one of two ways:

• Specify a CDN path to integrate Quick-fill
• Use the npm package to integrate Quick-fill

Once you've integrated the LIFF SDK into your LINE MINI App, you can enable the Quick-fill LIFF plugin by passing the Quick-fill LIFF plugin to the liff.use() method as shown below:

liff.use(new LiffCommonProfilePlugin());
await liff.init({ liffId: "xxx" });

const { data, error } = await liff.$commonProfile.get();
liff.$commonProfile.fill(data);

The $commonProfile property is added to the liff object, and the following Quick-fill client API can be used:

• liff.$commonProfile.get()
• liff.$commonProfile.getDummy()
• liff.$commonProfile.fill()

Specify a CDN path to integrate Quick-fill

When specifying a CDN path, by loading the package with the script tag, the liffCommonProfile property is added to the window object. An instance of the LiffCommonProfilePlugin class that exists within liffCommonProfile is passed as an argument to liff.use().

    <meta name="viewport" content="width=device-width, initial-scale=1.0" />

    <title>LIFF App</title>
  </head>
  <body>
    <div id="root"></div>
    <script type="module" src="/index.js"></script>
  </body>
</html>

liff.use(new liffCommonProfile.LiffCommonProfilePlugin());

const { data, error } = await liff.$commonProfile.get();
liff.$commonProfile.fill(data);

For more information, see Specify the CDN path in the LIFF documentation.

Use the npm package to integrate Quick-fill

When using the npm package, import the LiffCommonProfilePlugin class from the package and pass an instance of it as an argument to liff.use().

$ npm install @line/liff-common-profile-plugin

import liff from "@line/liff";
import { LiffCommonProfilePlugin } from "@line/liff-common-profile-plugin";
liff.use(new LiffCommonProfilePlugin());

const { data, error } = await liff.$commonProfile.get();
liff.$commonProfile.fill(data);

For more information, see Use the npm package in the LIFF documentation.

Quick-fill operating environment

Quick-fill only works when the user is using LINE for iOS or LINE for Android.

The following is the operating environment for Quick-fill on your system:

• LIFF SDK version
• Node.js version

LINE MINI Apps use the LINE Front-end Framework (LIFF). For more information about the recommended environment for Quick-fill, see the Recommended operating environment section of the LIFF documentation.

LIFF SDK version

Use LIFF SDK v2.19.0 or later, as the LIFF plugin is used in the development of Quick-fill. For more information on LIFF plugin, see LIFF plugin in the LIFF documentation.

Node.js version

When installing the LIFF SDK using npm, use Node.js version 18.15.0 or later. Note that Node.js isn't required when using the LIFF SDK with a specified CDN path.

For more information on integrating the LIFF SDK into your LIFF app, see Integrating the LIFF SDK with the LIFF app in the LIFF documentation.

Types of scope that can be selected in the LINE Developers Console

You can select the following types of Quick-fill scopes in the LINE Developers Console.

If these scopes don't display on the LINE Developers Console, see 1. Apply to use Quick-fill.

Users cannot select and allow some scopes on the channel consent screen. They can either allow or disallow these scopes as "Management Information (Common Profile) in the Account Center" in bulk.

The scopes parameters that can be specified and its return value

The scopes parameters that can be specified for liff.$commonProfile.get() and liff.$commonProfile.getDummy() and the return values for each are as follows:

The Common Profile for the Account Center is created by combining the profile registered with LINE and Yahoo! JAPAN. If the user doesn't use the Account Center, the profile information from LINE will be filled in automatically.

Dummy data for Common Profile that can be obtained

You can use liff.$commonProfile.getDummy() to get dummy data for Common Profile. You can specify the dummy data to get with caseId from the 10 types provided.

Options for getting Common Profile information

When getting Common Profile information using liff.$commonProfile.get(), you can specify the following options for each scope. These options are all set to true by default, so specify false to disable them.

API reference
