+# ASP.NET Core MVC / Razor Pages UI: JavaScript Notify API
+
+Notify API is used to show toast style, auto disappearing UI notifications to the end user. It is implemented by the [Toastr](https://github.com/CodeSeven/toastr) library by default.
+
+## Quick Example
+
+Use `abp.notify.success(...)` function to show a success message:
+
+````js
+abp.notify.success(
+    'The product "Acme Atom Re-Arranger" has been successfully deleted.',
+    'Deleted the Product'
+);
+````
+
+A notification message is shown at the bottom right of the page:
+
+![js-message-success](D:/Github/abp/docs/en/images/js-notify-success.png)
+
+## Notification Types
+
+There are four types of pre-defined notifications;
+
+* `abp.notify.success(...)`
+* `abp.notify.info(...)`
+* `abp.notify.warn(...)`
+* `abp.notify.error(...)`
+
+All of the methods above gets the following parameters;
+
+* `message`: A message (`string`) to show to the user.
+* `title`: An optional title (`string`).
+* `options`: Additional options to be passed to the underlying library, to the Toastr by default.
+
+## Toastr Configuration
+
+The notification API is implemented by the [Toastr](https://github.com/CodeSeven/toastr) library by default. You can see its own configuration options.
+
+**Example: Show toast messages on the top right of the page**
+
+````js
+toastr.options.positionClass = 'toast-top-right';
+````
+
+> ABP sets this option to `toast-bottom-right` by default. You can override it just as shown above.
