I'm trying to setup a PayPal Payout. I've got my API calls going through but in the sandbox I keep getting: Sender has insufficient funds. How can I add funds to my application? I can't seem to find an option to specify an account to send from.
For the mass payments you must have the PayPal balance . For the sandbox while creating the account it prompt you to specify the amount to show in the PayPal balance . But if you have missed that , you can create the new sandbox account and specifying the amount this time .
Otherwise you can provide your sandbox email address I can transfer you the money from my sandbox account to continue with the same sandbox account .
