Contact management

Contact management refers to operations such as adding and removing contacts, and adding and removing users from the block list.

This page shows how to call the Chat RESTful APIs to create and manage contacts.

Before calling the following methods, make sure you understand the call frequency limit as described in Limitations.

Common parameters

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

Request parameters

ParameterTypeDescriptionRequired
hostStringThe domain name assigned by the Chat service to access RESTful APIs. For how to get the domain name, see Get the information of your Chat project.Yes
org_nameStringThe unique identifier assigned to each company (organization) by the Chat service. For how to get the org name, see Get the information of the Chat project.Yes
app_nameStringThe unique identifier assigned to each app by the Chat service. For how to get the app name, see Get the information of the Chat project.Yes
usernameStringThe unique login account of the user. The user ID must be 64 characters or less and cannot be empty. The following character sets are supported:
  • 26 lowercase English letters (a-z)
  • 26 uppercase English letters (A-Z)
  • 10 numbers (0-9)
  • "_", "-", "."
  • The username is case insensitive, so Aa and aa are the same username.
  • Ensure that each username under the same app is unique.
  • Do not set this parameter as a UUID, email address, phone number, or other sensitive information.
Yes

Response parameters

applicationNameStringThe unique identifier assigned to each app by the Chat service . This is the same as app_name.
uriStringThe request URI.
pathStringThe request path, which is part of the request URL. You can safely ignore this parameter.
entities JSONThe response entity.
entities.uuidStringThe user's UUID. A unique internal identifier generated by the Chat service for the user in this request. This is used for generating the user token.
