/**
 * <a href="https://stripe.com/docs/connect">Stripe Connect</a> platforms can reverse transfers made to a
 * connected account, either entirely or partially, and can also specify whether
 * to refund any related application fees. Transfer reversals add to the
 * platform's balance and subtract from the destination account's balance.
 *
 * Reversing a transfer that was made for a <a href="/docs/connect/destination-charges">destination
 * charge</a> is allowed only up to the amount of
 * the charge. It is possible to reverse a
 * <a href="https://stripe.com/docs/connect/separate-charges-and-transfers#transfer-options">transfer_group</a>
 * transfer only if the destination account has enough balance to cover the
 * reversal.
