When a payout to an organization declines, you should receive a notification with a long error code. At the very beginning of the notification you'll see the name of the organization for which the payout declined. Within the error message there will be both an authorization amount and a three character return or response code. The authorization amount helps you verify which payout declined and the response code clarifies the reason for the failed payout.
R03 - No Account | The account is closed or doesn't match the name entered by the organization with their payment info.
R04 - Invalid Account Number | The account number structure entered by the organization is invalid.
U02 - Account Not Approved | Occurs when a payout has had three consecutive payouts return due to an R03 or R04. No more payouts will be attempted by the system until the organization corrects their bank account information.

In each of these cases, the solution is to have the organization correct their bank account information in the Payment tab of their Organization Settings. The system will then reattempt any previously declined payouts that night.
