exchange_rate property
The exchange rate used, if applicable, for this transaction. Specifically, if money was converted from currency A to currency B, then the amount in currency A, times exchange_rate, would be the amount in currency B. For example, suppose you charged a customer 10.00 EUR. Then the PaymentIntent’s amount would be 1000 and currency would be eur. Suppose this was converted into 12.34 USD in your Stripe account. Then the BalanceTransaction’s amount would be 1234, currency would be usd, and exchange_rate would be 1.234.
