Chat RESTful API overview

Chat provides RESTful APIs through the REST platform. You can send HTTP requests to the Agora server through your business server to realize real-time communication on the server side.

The Chat REST platform provides a multi-tenant architecture to manage resources in the form of a Collection. A Collection contains the following:

• Database
• Organizations (orgs)
• Apps (apps)
• Users (users)
• Chat groups (chatgroups)
• Chat messages (chatmessages)
• Chat files (chatfiles)

The user data of different orgs is isolated from each other. Under the same org, the user data of different apps is also isolated from each other. The data structure of an org is as follows:

Ensure that you meet the following requirements before calling the Chat RESTful APIs:

• You have enabled and configured Chat in the Console.
• You have retrieved an app token from the app server. For details, see Authentication with App Token.

This group of methods enable you to implement user system management, including user registration, retrieving users, modifying user attributes, and deleting users.

The Chat RESTful APIs require Bearer HTTP authentication. Every time an HTTP request is sent, the following Authorization field must be filled in the request header:

_1

Authorization: Bearer ${token}

In order to improve the security of the project, Agora uses a token (dynamic key) to authenticate users before they log in to the chat system. The Chat RESTful APIs only supports authenticating users using app tokens. For details, see Authentication using App Token.

Under the same project, all requests are sent to the same domain name. For how to get the domain name, see Get the information of the Chat project.

To ensure communication security, the Chat RESTful APIs only support the HTTPS protocol.

• Request: See the sample code of each API for the data format of the request.
• Response: The format of the response is JSON.

All request URLs and request bodies are case sensitive.
