When using the CSV User Import feature, is an external ID, alias, or Braze ID required for each user?

In the context of using the CSV User Import feature in Braze, an external ID, alias, or Braze ID is indeed required for each user being imported. This requirement is crucial because these identifiers help Braze accurately associate the imported data with existing user profiles or create new profiles when they do not already exist.

Using an external ID, alias, or Braze ID ensures that the import process maintains data integrity and avoids duplication of user records. Each identifier works as a unique key to link the user's data correctly, allowing for effective user engagement and tracking. Without these identifiers, it would be challenging to accurately assign the associated data to specific users, which could lead to confusion and potential data errors during the import process. Therefore, adhering to this requirement is essential for successful data management within the Braze platform.
