Payment on the site without leaving the site itself (Yandex.Money)

Question

Yandex

Please tell me if it is possible to accept Yandex.Money from project users WITHOUT going to their website.
Any option is interesting from:
1) iframe (it is not safe and most likely closed by Yandex)
2) billing
I’m just interested in the answer - is it possible or not, I will find the subtleties, if possible.
Just someone who has already done this will quickly be able to answer the question.

Answer 1

I don’t have an answer, but rather a comment ...
I don’t trust such things and I’m suspicious.

Answer 2

Impossible, because to pay the user redirects via https to the Yandex page, signed with a Yandex certificate. The certificate is bound to a domain. All this is done so that unscrupulous owners of online stores who shit on our personal data could not collect passwords from users' wallets in this way.
Even if you manage to somehow implement the frame, then Yandex will quickly burn this business and put you on the black list of sellers.

Answer 3

it is possible, but not iframe, but a little differently
