Closing Behavior

Mini Apps are intended to handle different, and at times, complex scenarios where the user can navigate deep into the application architecture. It's a common situation when a user is following a specific workflow, such as purchasing an airplane ticket, which involves multiple steps.

Accidentally closing a Mini App with data loss can be a significant disappointment for the user. To prevent this, developers have the option to configure the closing behavior and prompt the user before closing the application.

To enable closing confirmation, Telegram Mini Apps provides a method called web_app_setup_closing_behavior.
