Application for Bitrix24 (cloud) integration with wayforpay.com

Good afternoon!
There is a system for accepting payments wayforpay.com
She has an open API.
And theres Bitrix24 cloud at the maximum rate.
It is necessary that we can invoic customers in our bitrix by choosing a payment method wayforpay.com. Plus accept payment for the transaction. That is, to appear waiforpei here as on the screenshots attached.

In bitrix now there is no application for integration with waiforpei, and the waiforpei itself is very flexible to quickly make integration...
