Availability
Additional account creation is available only when your organization’s accepted package includes an unused account slot. Eligible organization administrators see Add account in the account selector. When capacity is not available, Interchange does not show a creation or upgrade action, and API requests fail without changing the organization or creating a partial account. Some direct Advertiser packages include one account. Advertisers and connected advertising-platform accounts do not consume organization account slots. When creating an eligible Buyer account, Operator domain means the domain of the organization operating that account. For a Seller account, Company domain means the company operating the storefront; it initially seeds the operator domain and remains separate from the storefront’s public listing domain. For the package-authorized API operation, see the Buyer or StorefrontPOST /api/v2/accounts/create-child reference.
