Interface LegacyCreateMediaBuySuccess

Cooldown period between consecutive exposures to the same entity. Prevents back-to-back ad delivery (e.g. {"interval": 60, "unit": "minutes"} for a 1-hour cooldown). Preferred over suppress_minutes.

Maximum number of impressions per entity per window. For duration windows, implementations typically use a rolling window. campaign applies across the owning field's full flight: the package flight for a targeting overlay, or the MediaBuy flight for a root cap.

Entity granularity for impression counting. Required when max_impressions is set.

Time window for the max_impressions cap (e.g. {"interval": 7, "unit": "days"} or {"interval": 1, "unit": "campaign"} for the full flight). Required when max_impressions is set.

Explicitly use seller/provider automatic bidding at this authored scope. At package scope this is a complete override of a media-buy policy, not inheritance. It MUST be the only field in the block and MUST be preserved on readback.

Manual auction bid denominated in the media-buy currency and expressed per the selected pricing option's auction unit. For example, a CPM option interprets the amount per thousand impressions. This is the amount submitted to the auction, not a promise that the clearing price equals it. Requires an auction-priced pricing option whose currency equals the media-buy currency.

Hard per-auction ceiling denominated in the media-buy currency and expressed per the selected pricing option's auction unit. This is the only canonical hard auction ceiling and MUST NOT be translated into an average outcome-cost control. Requires an auction-priced pricing option whose currency equals the media-buy currency. May stand alone or supplement cost_per/roas only when the relevant scope capability advertises that combination.

Average cost control per result of the scope-bound primary optimization goal. At seller-optimized media-buy scope it binds to budget_allocation.optimization_goals; at package scope it binds to that package's optimization_goals; at fixed media-buy scope it binds independently to each inheriting package and is valid only when their primary-goal result units are compatible. Metric goals are compatible only when metric and every result-defining qualifier match; vendor_metric goals only when vendor and metric_id match; event goals only when the event_type/custom_event_name set and resolved attribution_window match. Primary is the earliest array entry among goals tied for the lowest explicit numeric priority; unprioritized goals follow explicitly prioritized goals; when all priorities are absent, the first entry is primary.

Dimensionless return-on-ad-spend control bound to the same scope-specific primary goal rules as cost_per. The bound goal must be value-bearing; a fixed media-buy default requires a value-bearing primary goal on every inheriting package. Every referenced value-bearing event source MUST declare value_currencies containing the media-buy currency. The seller validates this at buy creation; each buy consumes only exact-currency records, while other declared currencies remain available to other buys. Sellers MUST NOT perform currency conversion.

Seller's unique identifier for the package

ID of the product this package is based on. For packages created from an explicit create_media_buy package request, sellers MUST echo the request package's product_id on every response package object that represents that requested package.

Exact immutable audience-evidence snapshots that affected recommendation, eligibility, or package construction. A confirmed package MUST include a package_construction selection matching every buyer audience_evidence_pin and every snapshot used to satisfy package audience_evidence_requirements; this readback remains mandatory on subsequent package read surfaces. This is decision provenance only; applied targeting remains exclusively in targeting_overlay and targeting_resolution.demographics.

Hard lifetime spend cap for this package in the media-buy currency. Every selected pricing option in an AdCP-authored media buy MUST declare that same currency. In seller-optimized allocation mode this is a ceiling, not a current allocation. May be omitted when the package is bounded only by the shared media-buy total.

Soft lifetime spend target accepted for this package under seller-optimized budget allocation. This is an allocation preference, not a billing or delivery guarantee.

The hard package spend ceiling per shared media-buy cap day, in the media buy's currency. Sellers MUST echo this whenever a package daily cap is set. It is a subordinate ceiling, not a reserved or current allocation; the media buy's budget_cap_timezone defines its day boundary.

ID of the selected pricing option from the product's pricing_options array

Package-authored bidding policy, echoed only when the buyer authored a package override. {automatic:true} is an explicit automatic-bidding override. Omission means the package inherits media-buy bidding or, when both scopes are absent, uses provider automatic delivery. Monetary fields are denominated in the media-buy currency. Sellers MUST NOT materialize inherited media-buy policy here.

Impression goal for this package

Catalogs this package promotes. Each catalog MUST have a distinct type (e.g., one product catalog, one store catalog). This constraint is enforced at the application level — sellers MUST reject requests containing multiple catalogs of the same type with a validation_error. Echoed from the create_media_buy request.

Structured 3.1+ format option references supplied for this package on create_media_buy. Sellers SHOULD echo this field whenever the request included it. Publisher-catalog-backed options are identified by { scope: "publisher", publisher_domain, format_option_id }; product-local options are identified by { scope: "product", format_option_id } and resolve only against this package's target product. Omitted means the request did not carry format_option_refs unless the seller cannot reconstruct legacy requests created before this field was persisted.

Parameters for the direct canonical selector in format_kind, echoed from the create_media_buy request whenever the request included it. Requires format_kind; omitted only when the request did not carry direct canonical params or when the seller cannot reconstruct legacy requests created before this field was persisted.

Agreed performance standards for this package. When any entry specifies a vendor, creatives assigned to this package MUST include corresponding tracker_script or tracker_pixel assets from that vendor.

The binding reporting contract for this package — what the seller has agreed to populate in delivery reports. Each entry carries an explicit committed_at timestamp, so the array also serves as the contract amendment ledger: day-1 commitments share committed_at = create_media_buy.confirmed_at; mid-flight additions carry their own timestamps. When create_media_buy.confirmed_at is null for a provisional buy, sellers MUST omit committed_metrics until commitment. The first response that sets confirmed_at MAY include the initial committed-metrics set, and each such entry's committed_at MUST equal confirmed_at. The missing_metrics field on get_media_buy_delivery reconciles against this list, filtering to entries where committed_at < reporting_period.end (a metric committed mid-flight is only audited from its commitment timestamp forward). Sellers stamp the day-1 set on the create_media_buy response; mid-flight additions are appended via update_media_buy (append-only — sellers MUST reject attempts to modify or remove existing entries with validation_error, suggested code: IMMUTABLE_FIELD). Optional in v1; absence means the seller does not provide an audit-grade contract and missing_metrics falls back to the product's live available_metrics (a known audit gap — buyers SHOULD treat absence as 'no audit-grade contract' rather than 'clean delivery'). Each entry uses an explicit scope discriminator: standard for entries from the closed available-metric.json enum, vendor for vendor-defined metrics anchored on a BrandRef. Standard entries are symmetric with by_package[].metric_values; vendor entries reconcile to by_package[].vendor_metric_values; both use by_package[].missing_metrics for gaps. The atomic key remains (scope, metric_id, qualifier), with vendor identity included for vendor scope. Replaces the parallel-array design that shipped briefly in #3510.

Creative assets assigned to this package, including the committed package-scoped rotation policy. Omitted rotation_mode reads as weighted for backward compatibility; all assignments resolve to one effective mode, and sequential positions are unique within each package-local group.

Immutable canonical creative contracts established for this package. Each entry is a PackageFormatSnapshot of the selected effective Product format declaration. A package whose selected format carries tracker_execution_contract MUST retain and return this checklist even after creative coverage is complete; the live Product is never substituted for the package snapshot.

PackageFormatSnapshot entries from formats_to_provide that do not yet have creative coverage through sync_creatives or inline assignment. Every entry MUST equal its formats_to_provide snapshot after RFC 8785 canonicalization and, when product_snapshot_digest is present, carry the identical digest. An empty emitted array means every required format is covered. Absence means readiness was not reported.

Optimization targets for this package. The seller optimizes delivery toward these goals in priority order. Common pattern: event goals (purchase, install) as primary targets at priority 1; metric goals (clicks, views) as secondary proxy signals at priority 2+.

Flight start date/time for this package in ISO 8601 format. When omitted, the package inherits the media buy's start_time. Sellers SHOULD always include the resolved value in responses, even when inherited.

Flight end date/time for this package in ISO 8601 format. When omitted, the package inherits the media buy's end_time. Sellers SHOULD always include the resolved value in responses, even when inherited.

Whether this package is paused by the buyer. Paused packages do not deliver impressions. Defaults to false.

Whether this package has been canceled. Canceled packages stop delivery and cannot be reactivated. Defaults to false.

Cancellation metadata. Present only when canceled is true.

Agency estimate or authorization number for this package. Echoed from the buyer's request. When present on the package, takes precedence over the media buy-level estimate number.

ISO 8601 timestamp for creative upload or change deadline for this package. After this deadline, creative changes are rejected. When absent, the media buy's creative_deadline applies.

Seller-assigned media buy identifier. Optional on a purchase-phase prepare/check because the service may not assign the identifier until commit; required on modification and delivery lifecycle checks.

Proposal snapshot being executed or currently governing the MediaBuy.

Digest of the proposal commercial_terms. The governance agent compares it to the digest bound during the intent check.

Geographic targeting the seller will apply.

Channels the seller will deliver on.

Actual flight start the seller will use.

Actual flight end the seller will use.

Human-readable summary of the audience the seller will target.

Structured audience targeting the seller will activate. Each entry is either a signal reference or a descriptive criterion. When present, governance agents MUST use this for bias/fairness validation and SHOULD ignore audience_summary for validation purposes. The audience_summary field is a human-readable rendering of this array, not an independent declaration.

Total budget the seller will deliver against.

Hard aggregate daily spend ceiling the seller will enforce. Governance checks compare it with the authorized execution controls; it does not allocate spend to packages.

IANA timezone defining the calendar-day boundary for every daily cap on the planned media buy.

ISO 4217 currency code for the budget. Governance execution checks require it whenever total_budget is present and require it to match the intent-authorized currency.

Seller-accepted cross-package allocation authority and goals. Presence with seller_optimized mode means automatic within-buy reallocations are part of the committed delivery, not separate modification actions.

Seller-interpreted media-buy bidding policy used for governance and delivery transparency. Goal-bound controls follow budget-allocation scope semantics and monetary fields use the planned delivery currency. Package-authored overrides, including explicit automatic overrides, remain on packages rather than being copied into this aggregate field.

Registry policy IDs the seller will enforce for this delivery.

Short human-readable explanation. Treat as untrusted seller text and do not require buyers to parse it for routing.

Optional seller-specific structured diagnostics. AdCP 3.2 defines interoperability through code and affected_resource only; buyers MUST NOT require portable keys inside details. Seller extensions that are not direct diagnostics belong in ext.
