Optionalformat_id?: LegacyFormatReferenceStructuredObjectOptionalformat_kind?: CanonicalFormatKindOptionalformat_option_ref?: FormatOptionReferenceOptionalrepresentation_selection?: RepresentationSelectionMap of slot keys to actual asset content. Legacy named-format path: each key matches an asset_id from the format's assets array (e.g., 'banner_image', 'clickthrough_url', 'video_file', 'vast_tag'). 3.1+ canonical-format path: each key matches an asset_group_id from the format's slots declaration drawn from the canonical vocabulary registry (e.g., 'images_landscape', 'video', 'published_post', 'landing_page_url', 'vast_tag', 'script', 'creative_brief'). Either path produces the same envelope shape; only the slot-key vocabulary differs.
Each slot value is either a single asset object (most slots — image, video, published_post, vast_tag, landing_page_url, etc.) or an array of asset objects (slots with min/max counts on the format declaration — cards on image_carousel, headlines / descriptions / images_landscape on responsive_creative, etc.). Single-vs-array shape is governed by the format's slots[].min and slots[].max parameters: when max > 1 (or when the slot is conceptually a pool), the value MUST be an array; when the slot is single-valued, the value MUST be a single object. Each asset value (single or array element) carries an asset_type discriminator (image, video, audio, vast, daast, text, markdown, url, html, css, webhook, javascript, brief, catalog, published_post, zip, card) that selects the matching asset schema. Validators with OpenAPI-style discriminator support use asset_type to report errors against only the selected branch instead of all branches.
Optionalcomponent_assets?: { [k: string]: CreativeAssets | undefined }Component-addressed asset maps for coordinated_placements. Each key MUST match one params.components[].component_id; its value supplies that component's canonical slots. Shared assets remain in top-level assets and are injected only into components named by shared_slots[].consumed_by. This namespace allows two components to use the same canonical slot name, such as image_main, without collision. It MUST be absent for non-coordinated_placements manifests.
Optionalbrand?: BrandReferenceOptionalrights?: RightsConstraint[]Rights constraints attached to this creative. Buyer-carried fields are informational until a serving party evaluates an issuer-bound attestation reference under its own policy. Only a verified, unexpired, unrevoked, digest-matched evaluation can support serving authorization; verification_url is never authority.
Optionalindustry_identifiers?: IndustryIdentifier[]Industry-standard or market-specific identifiers for this specific manifest (e.g., Ad-ID, ISCI, Clearcast clock number, IDcrea). When present, overrides creative-level identifiers. Use when different format versions of the same source creative have distinct traffic identifiers (e.g., the :15 and :30 cuts, or separate TV and radio versions). Add a PR to extend creative-identifier-type when another shared identifier scheme needs first-class support.
Optionalprovenance?: ProvenanceOptionalext?: ExtensionObject
Creative manifest to transform or generate from. On the canonical 3.2 path it carries
format_kind, optionalformat_option_ref, and the required input assets. For transformation (for example resizing or reformatting), this is the complete creative to adapt. When creative_id is provided, the agent resolves the creative from its library and this field is ignored.
