• False
• True

The correct answer is: False

Explanation: The statement “AMC audiences is an API-only feature” is false.

AMC audiences can be managed via both API and the Amazon Ads Console user interface. Advertisers can create, view, and activate AMC audiences in the Amazon Ads console as well as programmatically through API endpoints.

Reference content: From the official Amazon documentation (Rule-based audiences):

“Advertisers can use queries to create custom audiences in AMC for use in Amazon DSP, Sponsored Brands, Sponsored Products, and Sponsored Display … These audiences can be activated and managed in the Amazon DSP console or via API endpoints.”

The documentation describes audience operations, both through API and UI workflow, including steps to view and use custom audiences in advertiser platforms.
