User Overview
App users need to connect to RC services to use the IM service. For RC, a user is an App user who holds a valid Token issued by RC and connects to and uses the IM service.
Register User
The App Server should provide the user ID (userId) of the App user to the RC server to obtain a unique user Token. For RC, this step of obtaining a Token with userId is referred to as Register User, and it must be completed by calling the Server API.
The App client must hold a valid Token to successfully connect to the RC server and use the RC IM service. When an App client user sends a login request to the server, the server will query the database to check if the connection request matches.
User Registration Limit
- The maximum number of registered users in the Development environment? is 100.
- In the Production environment?, there is no limit to the number of registered users after upgrading to the Chat Premium Plan or Chat Ultimate Plan.
Delete User
Deleting a user refers to removing a registered test user in the Development environment through the Console to control the total number of test users in the development environment. This operation is not supported in the Production environment.
Deactivate User
Deactivating a user refers to deleting user data in the RC service. Apps can use this capability to implement their own user deactivation feature to meet App store or compliance requirements.
After RC returns a successful deactivation result, the data related to the user ID is deleted. You can query RC for all deactivated user IDs. If needed, you can reactivate a deactivated user ID (note that user personal data cannot be restored).
Only the IM Server API provides the above capabilities.
User Information
User information generally refers to the user's nickname, avatar, as well as group nicknames, group avatars, and other data. The RC server does not provide user profile hosting and maintenance services.
The IMLib SDK does not provide client-side interfaces related to user information.
Friend Relationship
The friend relationship between App users needs to be maintained by the App Server. RC does not synchronize or save friend relationship data from the App.
If you need to restrict message sending and receiving behavior between client users (for example, if all userIds of the App are leaked, allowing a malicious user to bypass the friend relationship and send messages to any user), you can consider using the User Allowlist service. Once a user enables and sets an allowlist, they can only receive messages from users in that allowlist.
