Placement Asset Customization

Updated: Jun 28, 2026

Use Placement Asset Customization to customize the creative assets displayed in different ad placements. Maintain control over each creative asset, while using several different placements.

Placement Asset Customization is one of three APIs that use asset customization rules. Learn more about Asset Customization Rules.

Get started

Step 1: Create an ad campaign and ad set
Step 2: Provide creative and customize assets
Step 3: Create your ad
Optional Step 4: Get insights and analyze results
Optional Step 5: Read Ad Creative

Placement Asset Customization with existing posts is no longer supported via the API. You can only use this option in Ads Manager.

Step 2: Provide creative

Use asset_feed_spec to provide your creative. You can specify multiple creative assets for each asset type, including images, videos, carousels, headlines, and body text. Only provide one link description, since the link description cannot be customized per placement.

To apply customization:

Set asset_customization_rules inside your asset_feed_spec.
For each rule, add customization_spec and asset labels.

For Placement Asset Customization, every asset_feed_spec needs to have more than one customization rule attached to it.

See Asset Customization Rules.
