Configuring Custom Path

This feature can only be used for verified MINI Apps

This feature is only available for verified MINI Apps.

Custom Path is a unique string that is set in the LIFF URL of published channel. The Custom Path feature allows you to set your own string in the LIFF URL as follows:

Example URL with LIFF ID	Example of setting Custom Path
https://miniapp.line.me/123456-abcdefg	https://miniapp.line.me/cony_coffee

For example, by setting a unique name as a Custom Path, users will be able to identify which brand or shop's LINE MINI App from the URL. Even when Custom Path is set, the URL by LIFF ID can still be accessed as before.

How to apply

If you use the Custom Path feature in your LINE MINI App, an application is required. The application differs depending on the area where the service is provided.

• If your service area is Japan
• If your service area is Taiwan or Thailand

You will be notified of the confirmation of your application and the result of the review by email. It'll take 1-2 weeks from the time of application until the URL by Custom Path becomes available.

Notes on applying for Custom Path

Even if a Custom Path is set, the LIFF URL with the Custom Path set won't be displayed on the LINE Developers Console.
