Correct answer: One-to-one and one-to-many integrations both need authentication to work..
Why this is the answer
Both integration types require controlled access before data or account actions can be performed. In Amazon Ads workflows, authorization ensures that an application has permission to act on behalf of an advertiser. Authentication confirms the identity of the application or user requesting access. This access control protects advertiser data and limits actions to approved scopes. The integration model changes account coverage, but it does not remove the need for secure access.
