What replaced the deprecated PayPal Adaptive payments API

[akheera_baloxh1]

My team and I had the PayPal Adaptive payments API integrated into our web app (which allows a user to withdraw funds, as they can sell items in the market place), and we were testing recently before launching. We began receiving the following error: 

errorId = 580001;
        message = "Invalid request: Unilateral payment is deprecated.";
        parameter =             (
            "Unilateral payment is deprecated.",
            "One or more receiver account is unconfirmed/does not exist."
        );
        severity = Error;

Looking at the documentation it states that it is now deprecated: https://developer.paypal.com/docs/archive/adaptive-payments/integration-guide/APIntro/Olansi

Does anyone know what has replaced this API? Is it the Payouts API? Or does anyone know any alternative APIs for what we are trying to accomplish?
