How do you track session data using the Braze SDK?

Tracking session data using the Braze SDK is performed automatically based on the app lifecycle, which is why this choice is the correct answer. The Braze SDK is designed to seamlessly manage session tracking without requiring developers to implement additional manual code for session initiation or termination.

When the app moves between the foreground and background states, the SDK automatically tracks these changes, handling session management internally. This allows for accurate collection of session data such as duration, user behavior, and engagement without extra overhead on the developer's part.

In contrast, manually implementing session tracking code requires significant effort and increases the likelihood of errors and inconsistencies. External analytics tools may provide additional insights but are not necessary for basic session tracking within the Braze framework. Lastly, limiting tracking to user login only would not capture the complete user experience or engagement within the app throughout its lifecycle. Thus, the automatic nature of the Braze SDK's session tracking reflects its design philosophy of simplicity and efficiency for developers.
