I’m having issues with this as well. I just tried to trigger an instant payout.. I’ve set up the adaptive payout API and the system told me I need to activate mass pay with paypal.
Failure. User is blocked (10329): We’re sorry, but your PayPal account isn’t currently eligible to send mass payments. Please contact either PayPal Customer Service or your account manager..
Does that make sense? Or do I have a setting wrong somewhere?
