Embedded store purchases

iOS and Android store purchases will be available after D2. This page currently defines boundaries only; it is not an available interface contract and must not be used to implement receipt submission or transaction restore.

Before the formal contract and SDK are published:

• Do not invent purchase endpoints.
• Retain the store_account_token from token exchange and pass it to system store APIs only as directed by the future guide.
• Do not write receipts, store account tokens, or purchase results to logs or analytics.
• For web orders, use the currently published Embedded order endpoints and rely on server order status for the final result.

After D2, this page will cover purchase, restore, repeated notifications, pending transactions, and sandbox testing.
