What is asset_feed_spec?
The Meta API structure that powers flexible and multi-placement ads.
asset_feed_spec is the Marketing API object that holds multiple images, videos, titles, and bodies for a single ad — the engine behind flexible (Advantage+ creative) ads and placement-customized ads. Meta tests combinations and serves the best per user and placement.
It's also how multi-ratio ads map 1:1, 4:5, and 9:16 assets to the right placements. Volume Creatives handles this automatically when you assign an ad format at launch.
