There are cases where you want to tell your API **users** that your app could call *their* app (sending a request) with some data, normally to **notify** of some type of **event**.

This means that instead of the normal process of your users sending requests to your API, it's **your API** (or your app) that could **send requests to their system** (to their API, their app).

This is normally called a **webhook**.

    /**
     * Redirects an authenticated user to the appropriate admin interface based on their roles.
     * Users with admin roles are redirected to the dashboard, while other users are redirected
     * to their designated admin action class or to the root if no specific action is available.
     *
     * @param user the authenticated user bean containing role information

If you need to have two independent FastAPI applications, with their own independent OpenAPI and their own docs UIs, you can have a main app and "mount" one (or more) sub-application(s).

/**
 * Converts Katakana characters to their corresponding Alphabet representations.

 * <p>
 * This class implements the {@link ReadingConverter} interface and provides a method to convert a given

     * The returned list of versions is only dependent on the configured repositories and their contents.
     * The supplied request may also refer to a single concrete version rather than a version range.
     * In this case though, the result contains simply the (parsed) input version, regardless of the

     * @param artifact the artifact for which to resolve the versions
