Which data import option into Braze is most likely to need engineering support?

The correct answer highlights that the Braze SDK is typically the data import option that requires engineering support. This is primarily because the Braze SDK involves integrating Braze functionality directly into the application code, which necessitates a deeper level of technical expertise.

Implementing the SDK requires developers to work with the application's architecture, ensuring that the SDK is correctly integrated for functionalities such as user tracking, messaging, and event reporting. This process often includes writing and testing code, which is a task that generally falls under the scope of engineering rather than marketing or analytics teams.

While data imports through CSV files and partner integrations might also have some level of technicality, they are more straightforward, often handled by non-engineering personnel and do not require as significant a change to the codebase or ongoing engineering support compared to SDK implementation. In contrast, the SDK's implementation is integral to the application's user experience and system performance, thus necessitating engineering involvement for successful integration and maintenance.
