What is the main purpose of the SDK in a Canvas app?

The main purpose of the SDK in a Canvas app is to facilitate Canvas app functionality. The SDK (Software Development Kit) provides developers with the necessary tools, libraries, and documentation to create and integrate applications within the Salesforce platform effectively. This includes the ability to interact with Salesforce data, handle events, and integrate app features seamlessly within the Salesforce user interface.

By using the SDK, developers can focus on building the core logic and user experience of the Canvas app without having to manage the underlying complexities of the Salesforce environment. This results in a smoother development process and a more cohesive user experience within Salesforce.

While managing user authentication, data visualization, and session management are certainly important aspects of an application, they are not the primary focus of the SDK itself in the context of Canvas apps. These functionalities can be addressed separately, but the SDK's role is to enable the overall functionality and integration of the app within Salesforce.
