Optionaladcp_The AdCP major version the buyer's payloads conform to. Sellers validate against their supported major_versions and return VERSION_UNSUPPORTED if unsupported. When omitted, the seller assumes its highest supported version.
Client-generated unique key for at-most-once execution. catalog_id gives resource-level dedup per catalog, but the sync envelope emits audit events and triggers platform review for large feeds — this key prevents those side effects from firing twice on retry. Also serves as a request ID on discovery-only calls (when catalogs is omitted). MUST be unique per (seller, request) pair. Use a fresh UUID v4 for each request.
OptionalcatalogsArray of catalog feeds to sync (create or update). When omitted, the call is discovery-only and returns all existing catalogs on the account without modification.
Optionalcatalog_Optional filter to limit sync scope to specific catalog IDs. When provided, only these catalogs will be created/updated. Other catalogs on the account are unaffected.
Optionaldelete_When true, buyer-managed catalogs on the account not included in this sync will be removed. Does not affect seller-managed catalogs. Do not combine with an omitted catalogs array or all buyer-managed catalogs will be deleted.
Optionaldry_When true, preview changes without applying them. Returns what would be created/updated/deleted.
Optionalvalidation_Optionalpush_OptionalcontextOptionalext
Request parameters for syncing catalog feeds with upsert semantics. Supports bulk operations across multiple catalog types (products, inventory, stores, promotions, offerings). Existing catalogs matched by catalog_id are updated, new ones are created. When catalogs is omitted, the call is discovery-only: returns all catalogs on the account without modification.
