Rules

Only the identificationField is mandatory;
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;
The cutoff time for immediate payments is 6:00 p.m.. Requests made after this time are settled on the next business day. Utility bills, taxes, or payments above BRL 250,000 can only be processed until 4:00 p.m.;
For overdue bills, payment will only be accepted if the issuer allows post-due settlement.
