We don’t want to collect your payment information before there is something to pay you for.
Therefore, you can only enter or change your payment information (e.g. IBAN, PayPal) when you request a new payout. To do so, you need to have reached the payout minimum of 6 Euros (or your currency equivalent).
Whenever you request a payment, make sure that your payment details are still correct. If they aren’t, create a new payout method.
