How to make a simple payment in Robokassa?

Question

ROBOKASSA

I have a site on WordPress, I sell only one service, I want the client to be able to pay for it directly on the site.
Registered in Robokassa, set everything up. But I don’t understand how to simply shove it into the site. So when installing WooCommerce, I will have to create a product and so on.
I just want the buyer to be able to drive in his full name, enter the amount and click pay. How to implement it?

Answer 1

No programming whatsoever.
