It works independently, and my intervention is required minimally. I am a tutor, and I have students with regular classes and set prices, so I decided to enable automatic payments for a certain period, which is very convenient for them. I paid an additional thousand rubles for this option, on top of the 10,000 rubles for the setup. This feature significantly simplifies life. It's also convenient for one-time payments — I create a link and send it to the student, and they can pay in any convenient way, even from abroad (although the commission is quite high).
