Payout to unregistered user with API REST
<p>I use the Paypal REST API to do single payout (<a href="https://developer.paypal.com/docs/api/#payouts" rel="nofollow">https://developer.paypal.com/docs/api/#payouts</a>). As receiver, I give an email address. All works as expected if I give an email corresponding to an existing Paypal sandbox account.</p>

<p>When I give an email that is not registered among my testing sandbox accounts, I would have expected than the receiver targeted by the payout would receive an email and be invited to create his Paypal account to claim his payout.</p>

<p>However, I got a <code>"RECEIVER_UNREGISTERED: Receiver is unregistered (https://developer.paypal.com/webapps/developer/docs/api/#RECEIVER_UNREGISTERED)."</code></p>

<p>To give an email as receiver linked to an existing Paypal is it really mandatory ? If yes, what is your app workflow to send a Paypal Payout to unregistered Paypal users ?</p>

<p>Thanks !</p>
