LINE MINI Apps do not automatically require verification, but certain features mandate it for publication. If verification is necessary, LINE meticulously reviews identity consistency, policy compliance, channel configuration, and user flows. To avoid delays, it's crucial to audit the submission thoroughly before requesting a review. Key features requiring verification include production service messages, custom paths, home-screen shortcuts, common profile quick-fill, and verified badges.Before submitting, align organizational identity across the LINE Developers Console, channel information, privacy policy, and channel description. Ensure the company name is consistent in all these locations and languages. Clearly describe the MINI App's workflow, identifying the primary user, core functions, and expected outcomes. Confirm that the Review channel accurately reflects the Published channel's features, transitions, data, authentication, and error states.Prepare comprehensive test scenarios for payments, reservations, and orders, including registration, successful and failed transactions, and data management. Thoroughly check privacy and terms pages for public accessibility, consistent company and service names, and accurate contact information. Verify that the MINI App's business category and content comply with LINE's policies, avoiding restricted categories and prohibited content.Request only necessary API scopes and document their usage. Service messages require a separate approval process and are strictly for confirmations or responses to user actions, not promotions. After verification, many settings become re-review sensitive, so freeze critical configurations like channel identity, legal URLs, and scopes before the initial submission. Plan for the verification timeline, which typically takes one to two weeks, and include a buffer for potential re-reviews. Finally, remember that MINI App verification is distinct from handling inbound customer messages.
