Stripe Treasury のアカウント構造
Treasury のアカウントコンポーネントの連携の仕組みについてご紹介します。
Use this guide to understand the technical components of Financial Accounts for platforms, specifically the different account types.
アカウントタイプ
Your platform must have Stripe Connect to use Financial Accounts for platforms. In its most basic form, a Connect integration includes a platform account with many connected accounts, each owned by a seller or service provider that uses the platform. Both the platform account and its connected accounts are Account objects in the Stripe API.
Financial Accounts for platforms only supports connected accounts that don’t use a Stripe-hosted dashboard and where your platform is responsible for requirements collection and loss liability, including Custom connected accounts. Learn how to create connected accounts that work with Financial Accounts for platforms.
As a platform with connected accounts, you’re responsible for maintaining a minimum API version, communicating terms of service updates to your connected accounts, handling information requests from them, and providing them with support. Because your platform is ultimately responsible for the losses your connected accounts incur, you’re also responsible for vetting them for fraud. To learn more, read the Financial Accounts for platforms fraud guide.

Financial Accounts for platforms includes another type of Stripe account, a financial account. When you onboard your platform to Financial Accounts for platforms, Stripe automatically creates and assigns a FinancialAccount
object to your platform account. As the platform, you request the treasury
capability when requesting the capabilities you need for your connected accounts. After you request it, Stripe updates the connected account’s Account
object to include additional requirements in its requirements hash. You can create financial accounts for your connected accounts, but until you gather the requirements from your connected account owners, the financial accounts aren’t accessible. For more information on using financial accounts, see Working with financial accounts.
アカウント残高
Each account in Stripe Connect (both platform and connected accounts) has an account balance that tracks pending and available funds for that account. With Financial Accounts for platforms, each of these accounts can also have a financial account, which has a balance of its own. You can use Financial Accounts for platforms to transfer funds between the platform account and financial account, but their respective balances always remain separate. However, you can’t transfer funds from a platform end-user’s financial account to their connected account. For more information on platform and connected account balances, see Understanding Connect account balances. For more information on financial account balances, see Working with balances and transactions.

アカウント間での資金の流れ
Although the payments balance and financial account balances are separate, Financial Accounts for platforms supports the flow of funds between the two. Financial Accounts for platforms also enables you to transfer funds from your platform financial account to the financial accounts attached to your platform’s connected accounts. You can use Payouts to send funds from your payment balance to your financial account or to the financial accounts attached to your platform’s connected accounts. To move money between two financial accounts, Financial Accounts for platforms uses OutboundPayment objects.
