This API is dedicated to seller promotion workflows. The important resources are ad_campaign, ad_group, ads, suggest_bids, and suggest_keywords rather than general account settings. The path tree includes "/ad_campaign", "/ad_campaign/find_campaign_by_ad_reference", "/ad_campaign/get_campaign_by_name", and "/ad_campaign/{campaign_id}".

That structure fits teams that want to create or update ad campaigns, fetch suggested bids and keywords for an ad group, and bulk-create ads by inventory reference. The spec lists scopes such as "https://api.ebay.com/oauth/api_scope/sell.marketing", "https://api.ebay.com/oauth/api_scope/sell.marketing.readonly", and "https://api.ebay.com/oauth/api_scope".

Focused on marketing rather than seller policy configuration There are many ad-specific entities to model before integration
