How to accept payments to Qiwi wallet without Qiwi merchant?

Question

Payment systems

I want to do this.
It is necessary to accept large payments through the site (6 thousand rubles each, for example). Automation, as in merchants, is not needed.
Because qiwi wallet can be topped up in a very wide network of terminals, through money transfers, etc., I want to make a form in which the client can choose how he will deposit money into my qiwi wallet. The first option is in cash (in Qiwi terminals, in MTS and Megafon stores, etc.). To do this, a map https://qiwi.ru/replenish/map.action is embedded on the site . Another option is through money transfer systems (Leader, for example). When choosing any of the methods, he is given instructions for replenishing my wallet using the selected method.
I do not want to reinvent the wheel, maybe there is a ready-made implementation?
