GetBills

Lists the bills of the API key’s supplier to the key’s company: the same bills the supplier’s external user sees in the portal, including bills the company entered itself. Use it to follow your bills’ status, due dates and payments. How keys, responses and statuses work is on Vendor bills.

`FromDate`, `ToDate`	The range of bill dates, as `yyyy-MM-dd`, both days included. At most 366 days apart. Required unless `BillNumber` is given.
`BillNumber`	One bill number. Capitals and spaces do not matter.
`Status`	Only bills with this status: `Draft`, `Submitted`, `Received`, `Approved`, `Rejected`, `Disputed`, or `Outstanding` for bills with an amount still due.
`Page`	The page to return. The first page is `1`, the default.
`PageSize`	Bills per page, from 1 to 500. The default is 100.

Bills come newest bill date first.

Paging

RetInfo holds the page and the total number of matching bills, so you can tell how many pages there are:

{
  "Code": 1,
  "Info": "",
  "RetInfo": {
    "Page": 1,
    "PageSize": 100,
    "Total": 2,
    "Bills": [
      { "BillID": 109827, "BillNumber": "INV-2026-0042", "Status": "Approved", "...": "..." },
      { "BillID": 109790, "BillNumber": "INV-2026-0038", "Status": "Rejected", "...": "..." }
    ]
  },
  "RowsAffected": 2,
  "Scalar": null,
  "Identity": 0
}

Each entry of Bills is a bill. RowsAffected is the number of bills on this page. A page past the last one returns no bills.
