# Message Notification Overview

> Introduces the different types and use cases of message notifications, the message notification API capabilities, and how to integrate them.

This document introduces the different types and use cases of message notifications, the message notification API capabilities, and how to integrate them.

## Message Notification Types

DingTalk provides the following types of message notifications:

* **Send Work Notifications Using a Template:**

  Message templates are an upgrade to the way Third-party enterprise apps push messages through Work Notifications. They provide simpler and more standardized development and configuration capabilities for message templates, while also offering more secure, manageable, and controllable message notification capabilities on the customer side. For more information, see [Message Template Overview](/zh/open/development/message-template-overview).

  **Note**

  Message templates are supported only for Third-party enterprise apps, not for Internal apps.

* **Work Notification Messages**:

  These are notification messages pushed to employees in the name of a Micro app within your organization's Work Notifications chat, such as birthday greetings and onboarding reminders.

## Message Notification API Capabilities

### List of Open Message Notification APIs

Message notifications offer rich API capabilities. Through the APIs, developers can integrate message notifications with their organization's business systems.

## Glossary

### task\_id

The `task_id` is the unique identifier field of a Work Notification message. It is returned when you call the [Send Work Notifications](/zh/open/development/asynchronous-sending-of-enterprise-session-messages) API.

Use the `task_id` to call the [Get the Sending Progress of a Work Notification Message](/zh/open/development/obtain-the-sending-progress-of-asynchronous-sending-of-enterprise-session) API and the [Get the Sending Result of a Work Notification Message](/zh/open/development/gets-the-result-of-sending-messages-asynchronously-to-the-enterprise) API to query the sending progress and result of a Work Notification message.
