How to automate the distribution of funds between wallets from different payment systems?

Question

Payment systems

You need a script, a payment aggregator or a payment system that would allow you to:
1. Accept payments (transfer funds) from different wallets of different payment systems to one
2. Redistribute them
3. Return funds back to the specified wallets
or
Withdraw from some wallets and send them to others according to a certain rule.

Answer 1

It is obvious that you need to start your own payment system.
