- Asaas automatically fills in the remaining bill details (amount, due date, bank, etc.) based on the information provided by the issuing bank and our payment partner;
- You don’t need to send fields such as
dueDate, value, interest, fine, or discount — unless they are strictly required due to specific commercial or business rules on your side;

- For overdue bills, payment will only be accepted if the issuer allows post-due settlement.
