Use this API to send a payment receipt after the payment has been created.
However, please note that the preferred method should always be to send the receipt while creating a payment by passing the email in the "receiptEmail" parameter in the request body of the "Create Payment API". The "Send Payment Receipt" should be used to send a second receipt copy at a later point after the payment has been completed.
