Initialization

Before using other features of the SDK, initialization must be performed first.

Obtain App Key

You must have the correct App Key to proceed with initialization.

You can view the App Keys of the applications you have created in the Console. If you have multiple applications, make sure to select the correct application name (labeled as 1 in the image below).

RC provides two sets of independent App Key / Secret for each application to isolate the production and development environments. When obtaining the App Key, please distinguish between the environments (Production / Development, labeled as 2 in the image below).

tip

• If you are not the creator of the application, we recommend confirming whether the data center displayed on the page meets expectations when obtaining the App Key.
• If you have not yet applied for the application to go live on RC, you can only use the development environment.

Initialization

Developers can obtain the IM instance object through the create method.

All interfaces within the SDK need to be called through the RCIMIWEngine object, which can only be obtained through the create method. After obtaining the entity object by calling the create method, developers need to save it themselves for subsequent interface calls.

Parameter Description

Parameter	Type	Description
appKey	string	The Appkey obtained by the developer in the Console
options	RCIMIWEngineOptions	Engine-related configuration

Code Example

let options: RCIMIWEngineOptions = {};
let engine: RCIMIWEngine = RCIMIWEngine.create(appkey, options);
