Submitting LINE MINI App
When you create a LINE MINI App channel, the LINE MINI App is an unverified MINI App, and some features are restricted. To make the developed LINE MINI App a verified MINI App, it's necessary to undergo a review by LY Corporation. This page explains how to submit the review.
Things to check prior to requesting review of your LINE MINI App
Prior to requesting review, check the following:
- Check whether your LINE MINI App adheres to all of the guidelines and rules.
In particular, check these guidelines and rules: - Check whether your LINE MINI App adheres to the LINE MINI App Policy
- Check whether the information you enrolled for the LINE MINI App Channel on the LINE Developers Console is accurate and up-to-date.
- The provider name must be the same as the "service provider".
- The correct service description must be provided in the Channel description.
- In the privacy policy, the company for which user data is acquired must be set to the same company as the provider name.
- Check whether the the LIFF URL of the Published channel and the LIFF URL of the Review channel reflect the same service.
- During review, LY Corporation checks the LIFF URL of the Review channel. The various settings within the channel and LIFF are automatically copied and reflected on the Review channel. However, make sure in advance that the LIFF URL of the Review channel reflects the same service as the LIFF URL of the Published channel.
Review period
It takes approximately 1-2 weeks for LY Corporation to complete its review process. If your application is rejected, it may take a few more days to re-apply and re-review. You can't specify the completion date of the review. Allow time to proceed with the review request.
When requesting review for multiple LINE MINI Apps
When requesting review for multiple LINE MINI Apps (multiple for the same package, or multiple for the same brand, etc.) at the same time, we recommend following this workflow to avoid duplicating efforts and reduce review time:
- First, request review for one LINE MINI App.
- Once your LINE MINI App has been approved, make a request for batch review.
Review Process
The general review process is as follows.
1. Submit an application for review in the LINE Developers Console
Enter the required information on the LINE Developers Console Review request tab and submit a request for review.
Once LY Corporation completes the review process, the review results will be displayed on the LINE Developers Console, as well as being sent to the email address you've registered on the LINE Developers Console.
If you've restricted access to your LINE MINI App, which is the subject of the review, by using basic authentication, inform us of the username and password in the Reference materials for the review on Review request tab when you request a review. For more information, see Use basic authentication to restrict access to your LINE MINI App before it is released.
Important points about the review
- After requesting the review, you may cancel it from the Cancel review request button on the Review request tab, as long as the review process hasn't already begun.
- Once LY Corporation begins the review process, you can't cancel your request or make changes to the information you entered.
- Once the review has begun and the status is "Reviewing", you can access the LIFF URL on the Review channel.
Services that include actions such as reservations, payments, and orders
For services that include actions such as reservations, payments, and orders, when submitting an application for review, you must enter test scenarios (accounts, products, stores, etc.) in Reference materials for the review.
Channel description
The review by LY Corporation will be based on the information provided in the Channel description on the Basic settings tab in the LINE Developers Console. For this reason, refer to the following example to provide the correct service details:
| Channel name | Channel description | |
|---|---|---|
| Bad example | LINE FRIENDS STORE | LINE FRIENDS STORE is a store for LINE character goods. |
| Good example | LINE FRIENDS STORE | This is a mobile ordering service at the LINE FRIENDS STORE. You can order and pay in advance and receive your merchandise at the store. |
For more information on Channel description, see Channel description.
When using in-app purchase
If you are using in-app purchase, you must first apply to use in-app purchase.
Once your application for in-app purchase has been approved, turn on the Apply to publish in-app purchase toggle button in the Review request tab to submit for review. If your application for in-app purchase is not yet approved, you can't submit for review to become a verified MINI App even if you turn on the toggle button.
While your in-app purchase application is under review, you can't submit an application for verification review.
Also, during the verification review, you can't apply to use the in-app purchase feature.
2. After your LINE MINI App has been approved
The workflow after being approved by the review depends on whether it's your LINE MINI App's first submission or your LINE MINI App has already been published as a verified MINI App.
When submitting your LINE MINI App for the first time
Once your LINE MINI App has been approved, the status of your channel will automatically change to "Approved" and immediately to "Reflected". Using the Search enable button from the Review request tab on the LINE Developers Console, the user will be able to search for your LINE MINI App within LINE.
Even if your status becomes "Reflected", users won't be able to search for your service yet because search hasn't been enabled within LINE.
When you want to make your service searchable, click the Search enable button and users will be able to immediately search for your LINE MINI App in LINE. However, if Search enable isn't activated within 30 days (including weekends and holidays) after the status becomes "Reflected", search will automatically be enabled at 9:00 AM JST on the 31st day.
For example, if your LINE MINI App status became "Reflected" on August 1, the "Search enable" feature will be automatically activated on 9:00 AM of August 31.
Once the search for your LINE MINI App is enabled, the status of the LINE MINI App channel will return to "Not yet reviewed" and you'll be able to change the settings and resubmit for review. At this point, any changes to the settings won't affect the currently published LINE MINI App until it passes the review process again and the Publish changes button is clicked.
Although the status is supposed to be automatically changed at 9:00 AM JST on the 31st day, there may be a 1-2 hour delay.
When your LINE MINI App has already been published as a verified MINI App
If the LINE MINI App is already published, the workflow is slightly different.
Once your LINE MINI App has been approved, the status of your channel will change to "Approved". Using the Publish changes button from the Review request tab on the LINE Developers Console, you will have to manually change the status of your channel to "Reflected".
Once your status becomes "Reflected", changes made at the time of the review request are updated in the Published channel and LIFF of the Published channel (e.g. LINE MINI App name, Channel settings, LIFF Settings, etc.).
When you want to publish your LINE MINI App, click the Publish changes button and the status will immediately change to "Reflected". However, if Publish changes isn't activated within 30 days (including weekends and holidays) after status becomes "Approved", the changes will automatically be reflected on 9:00 AM JST on the 31st day.
For example, if your LINE MINI App status became "Approved" on August 1, the new changes will be automatically activated on 9:00 AM of August 31.
Once the new changes are activated, the status of the LINE MINI App channel will return to "Not yet reviewed" and you'll be able to change the settings and resubmit for review. At this point, any changes to the settings won't affect the currently published LINE MINI App until it passes the review process again and the Publish changes button is clicked.
Although the status is supposed to be automatically changed at 9:00 AM JST on the 31st day, there may be a 1-2 hour delay.
Provider of a LINE MINI App channel that has passed review
If "Japan" is set to the Region to provide the service in the Basic settings tab on the LINE Developers Console, when the LINE MINI App channel passes review, the provider will be a certified provider.
