This topic describes how to create an ApsaraVideo Real-time Communication (ARTC) application and obtain the AppId and AppKey parameters for development.
Prerequisites
An Alibaba Cloud account is created and identity verification is complete. To create an Alibaba Cloud account, visit the Alibaba Cloud official website. For more information, see Create an Alibaba Cloud account.
Activate the service
Log on to the ApsaraVideo Live platform and click Buy Now. The service activation page appears.
Click Activate. The ApsaraVideo Live purchase page appears.

On the ApsaraVideo Live purchase page, set the billing method to Pay-by-traffic. For more information, see Standard live streaming pricing.
Read and accept the Terms of Service and Service Level Agreement. Then, click Activate Now. You can now use the console.

Step 2: Create an ARTC application
Go to the ARTC module in the ApsaraVideo Live console and click Create Application.

Enter a custom instance name. Both Chinese and English characters are supported. Read the Terms of Service and click Buy Now.
NoteThis purchase only creates an application and does not incur fees. Actual fees are billed based on your cloud usage. For billing details, see Billing of ARTC.

After the instance is purchased, return to the Applications page and refresh it to view the newly created ARTC application.

Step 3: Obtain development parameters
Click Manage in the Actions column to view the Application ID (AppId) and AppKey. AppId is the unique identifier of the application. These parameters are required when you call APIs to join channels and perform other operations.

Step 4: Obtain a token
A token is a signature-based security credential that authenticates identities and protects your cloud services from unauthorized access.
During development, you can generate tokens on the client side without deploying a token server. Before you publish your application, deploy your own token server. For more information, see Token-based authentication.
What's next
Integrate the ARTC SDK into your application. For details, see the SDK integration guide for your platform.
Configure co-streaming, social chat, or conferencing features for interactive live streaming scenarios.
