LINE MINI App Verification Review: A Pre-Submission Checklist That Prevents Rework

A successful launch of a LINE MINI App can be a game-changer for developers. However, understanding the verification process is crucial. Today, on August 3, 2026, we will explore how to prepare your LINE MINI App for verification, ensuring you meet all necessary requirements and avoid unnecessary delays.

Understanding Verification Requirements

Not every LINE MINI App needs verification before it can be published. The first question to ask is whether your app relies on features that require a verified status. Certain features do require verification, including:

• Production service messages
• Custom paths
• Home-screen shortcuts
• Common profile quick-fill
• Displaying a verified badge in the header

If your app does not include these features, you may publish it as an unverified MINI App initially. However, if you do need verification, plan for the review process before setting a launch date.

Step 1: Align Organizational Identity

Ensure that the provider name matches the service provider across all relevant documents. This includes:

• LINE Developers Console provider name
• Privacy policy company name
• Channel description

A simple internal record can help keep track of this:

{
  "providerName": "Example Company Ltd.",
  "serviceProviderName": "Example Company Ltd.",
  "privacyPolicyCompany": "Example Company Ltd.",
  "status": "matched"
}

Make sure that all names are consistent and clearly defined.

Step 2: Make the Channel Description Testable

Your channel description should clearly explain what your MINI App does. Instead of vague statements like "This is an online store," use a detailed description: "This LINE MINI App allows customers to select a store, order products, complete payment, and present the pickup code at the selected location."

This clarity helps reviewers understand and test your app effectively.

Step 3: Verify the Review Channel

Before submitting for review, confirm that the Review channel matches the Published channel in features, data, and user experience. Document the endpoints:

• Published endpoint: https://app.example.com/
• Review endpoint: https://review.example.com/

Ensure that both channels provide the same core features and user flows.

Step 4: Prepare Complete Test Scenarios

If your app involves reservations or payments, provide detailed test scenarios. For example:

{
  "scenario": "Complete a store pickup order",
  "account": {
    "username": "PROVIDED_IN_REVIEW_FORM",
    "password": "TEMPORARY_REVIEW_CREDENTIAL"
  },
  "preconditions": ["Test store is available", "Sample product is in stock"],
  "steps": [
    "Open the MINI App",
    "Select the test store",
    "Add the sample product",
    "Complete the test payment flow",
    "Open the order result"
  ],
  "expected_result": "Order confirmation is displayed"
}

Include various scenarios to cover all user flows.

Step 5: Check Privacy and Terms Pages

Review your privacy policy and terms of service pages. Ensure they are accessible, correctly named, and provide clear information about data collection and processing. Check these pages in a logged-out browser to confirm they are publicly reachable.

Step 6: Run a Policy Gate Before Technical Review

Even a technically sound app can be rejected if it violates LINE's policies. Review your content for compliance with restrictions on categories like gambling, dating, and adult content. Ensure that your app does not contain misleading claims or unsafe material.

Step 7: Review API Scopes

Request only the API scopes necessary for your app's functionality. Document each scope and its purpose. For example:

• Profile access: Required for identifying returning customers.
• Checkout: Required for payment processing.

Remove any experimental scopes that are not part of the submitted service.

Step 8: Treat Service Messages as a Separate Approval Gate

While verification allows for production service messages, each message template still requires separate approval. Make sure to follow the guidelines for these messages carefully.
