Create, delete, and retrieve threads

This page shows how to create, modify, delete, and retrieve a thread by calling Chat RESTful APIs. Before calling the following methods, ensure that you understand the call frequency limit described in Limitations.

Common parameters

The following table lists common request and response parameters of the Chat RESTful APIs:

Request parameters

Parameter	Type	Description	Required
`host`	String	The domain name assigned by the Chat service to access RESTful APIs. For how to get the domain name, see Get the information of your project.	Yes
`app_id`	String	The unique identifier automatically assigned to each project by Agora	Yes

Response parameters

Parameter	Type	Description
`action`	String	The request method.
`organization`	String	The unique identifier assigned to each company (organization) by the Chat service.
`application`	String	A unique internal ID assigned to each app by the Chat service. You can safely ignore this parameter.
`applicationName`	String	The unique identifier assigned to each app by the Chat service.
`data`	JSON	The details of the response.
`timestamp`	Number	The Unix timestamp (ms) of the HTTP response.
`duration`	Number	The duration (ms) from when the HTTP request is sent to the time the response is received.

Authorization

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:

Authorization: Bearer ${YourAppToken}

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. Chat RESTful APIs only support authenticating users using app tokens. For details, see Authentication using App Token.
