How to send email when paying via Yandex Money API?

Question

YuMoney

Hello! I want to connect the acceptance of payments through Yandex money. You need to know the email address of the payer. The client himself specifies the email before payment, and when the button is clicked, this email is sent to Yandex when paying. But this email does not come to the handler.
Is it possible to somehow send this email to the handler?
