Which method is utilized for importing user data into Braze for attributes?

The correct method for importing user data into Braze for attributes is through the CSV User Import. This approach allows you to upload a spreadsheet formatted in CSV, which can contain multiple attributes for users, enabling batch uploading of user information. This is particularly useful for large datasets where manual entry would be impractical. The CSV User Import process supports various user attributes, making it efficient for onboarding or updating user records in Braze.

Other methods mentioned, such as user segmentation, involve categorizing existing users based on specific criteria rather than importing data. API calls, while a robust method for real-time data integration, typically require programming knowledge and are used for dynamic or frequent updates rather than bulk imports. Batch processing refers generally to executing multiple transactions within a scheduled time frame and may not specifically pertain to user data import in the context of Braze.
