OpenIM is a service platform specifically designed for integrating chat, audio-video calls, notifications, and AI chatbots into applications. It provides a range of powerful APIs and Webhooks, enabling developers to easily incorporate these interactive features into their applications. OpenIM is not a standalone chat application, but rather serves as a platform to support other applications in achieving rich communication functionalities. The following diagram illustrates the interaction between AppServer, AppClient, OpenIMServer, and OpenIMSDK to explain in detail.
**OpenIMSDK** is an IM SDK designed for **OpenIMServer**, created specifically for embedding in client applications. Its main features and modules are as follows:
+ **REST API**: OpenIMServer offers REST APIs for business systems, aimed at empowering businesses with more functionalities, such as creating groups and sending push messages through backend interfaces.
+ **Webhooks**: OpenIMServer provides callback capabilities to extend more business forms. A callback means that OpenIMServer sends a request to the business server before or after a certain event, like callbacks before or after sending a message.
