/**
 * A <code>Transfer</code> object is created when you move funds between Stripe accounts as
 * part of Connect.
 *
 * Before April 6, 2017, transfers also represented movement of funds from a
 * Stripe account to a card or bank account. This behavior has since been split
 * out into a <a href="https://api.stripe.com#payout_object">Payout</a> object, with corresponding payout endpoints. For more
 * information, read about the
 * <a href="https://docs.stripe.com/transfer-payout-split">transfer/payout split</a>.
 *
 * Related guide: <a href="https://docs.stripe.com/connect/separate-charges-and-transfers">Creating separate charges and transfers</a>
 *
 * @property string $id Unique identifier for the object.
 * @property string $object String representing the object's type. Objects of the same type share the same value.
 * @property int $amount Amount in cents (or local equivalent) to be transferred.
 * @property int $amount_reversed Amount in cents (or local equivalent) reversed (can be less than the amount attribute on the transfer if a partial reversal was issued).
 * @property null|BalanceTransaction|string $balance_transaction Balance transaction that describes the impact of this transfer on your account balance.
 * @property int $created Time that this record of the transfer was first created.
 * @property string $currency Three-letter <a href="https://www.iso.org/iso-4217-currency-codes.html">ISO currency code</a>, in lowercase. Must be a <a href="https://stripe.com/docs/currencies">supported currency</a>.
 * @property null|string $description An arbitrary string attached to the object. Often useful for displaying to users.
 * @property null|Account|string $destination ID of the Stripe account the transfer was sent to.
 * @property null|Charge|string $destination_payment If the destination is a Stripe account, this will be the ID of the payment that the destination account received for the transfer.
 * @property bool $livemode Has the value <code>true</code> if the object exists in live mode or the value <code>false</code> if the object exists in test mode.
 * @property StripeObject $metadata Set of <a href="https://docs.stripe.com/api/metadata">key-value pairs</a> that you can attach to an object. This can be useful for storing additional information about the object in a structured format.
 * @property Collection<TransferReversal> $reversals A list of reversals that have been applied to the transfer.
 * @property bool $reversed Whether the transfer has been fully reversed. If the transfer is only partially reversed, this attribute will still be false.
 * @property null|Charge|string $source_transaction ID of the charge that was used to fund the transfer. If null, the transfer was funded from the available balance.
 * @property null|string $source_type The source balance this transfer came from. One of <code>card</code>, <code>fpx</code>, or <code>bank_account</code>.
 * @property null|string $transfer_group A string that identifies this transaction as part of a group. See the <a href="https://docs.stripe.com/connect/separate-charges-and-transfers#transfer-options">Connect documentation</a> for details.
