Enums

Some fields take one of a fixed set of values. Compare them exactly, including capitals and spaces: the API answers "Not Generated", not "NotGenerated".

paymentStatus

Incomes and expenses. Where a document stands on payment. Nuvio works it out from the payments matched to the document every time you read it, so it is never stale.

Pending 0

Nothing has been paid yet, and the due date has not passed.

PastDue 1

Not fully paid, and the due date has passed.

Paid 2

The matched payments add up to the total.

WaitingPayment 3

Partly paid, and the due date has not passed.

The expense and income list endpoints also accept the index (0–3) when you filter by status.

invoiceStatus

Incomes. Whether an invoice document has been made for the income, and sent.

Not Generated

No invoice document has been made yet.

Generated

The invoice document has been made.

Sent

The invoice has been sent to the customer.

transactionType

Bank transactions. Which way the money moved on the account.

Money In

Money received into the account.

Money Out

Money paid out of the account.
