What payment aggregators (payment systems) have an API for withdrawing money?

Question

Payment systems

Hello!
The essence of the issue is as follows, it is necessary to make a fundraising button (do not offer poison), after reaching the collected amount, automatically withdraw money in a predetermined way, to the specified details. In general, the functionality is like that of the "donate" button, the difference is that there the money is credited to the poison and you withdraw it yourself, but you need the money to be withdrawn through the API without user intervention.

Answer 1

POISON, WebMoney, and then only aggregators
