Invoices

Read-only access to a company's invoices, including line items, taxes, linked purchase orders, and files. By default, list results exclude uploads classified as not-an-invoice (NI) or wrong (W); pass status explicitly to include them.

Syncing invoice data: two things to know

1. updatedAt tracks the invoice itself, not its children. Changing a line item, tax row, or invoice-purchase-order link does not bump the invoice's updatedAt. Polling ?updatedAtFrom= alone will therefore miss invoices whose only change was in nested data. Run a periodic full reconcile in addition to incremental polling.
2. File URLs expire after 10 minutes. The url on each file is a presigned link. Download files during the same sync pass; do not store the URLs.
