Client-Server API

Understanding the Matrix Client-Server API

What is the Client-Server API?

The Matrix Client-Server API is the primary interface between Matrix clients (like Element, FluffyChat, etc.) and your homeserver. It handles user authentication, message sending/receiving, room management, and all other client operations.

Technical Reference: The Client-Server API is defined in the Matrix Client-Server API Specification. Your homeserver must implement this API for clients to connect.

This page is a Work in Progress and therefor missing deeper explanations for endusers. For technical users please refer to the Matrix Client-Server API Specification.
