Upload your invoice

POST/v1/orders/{id}/invoice

scope orders.write

YOUR fiscal invoice for the goods — Biklo does not issue it. Send a multipart file, or a url we reference without downloading.

Request body#

FieldTypeRequiredDescription
urlstringoptionalA link to your invoice. Required UNLESS you upload the document itself. Must parse as a URL, and is stored as a reference — we never fetch it, so it has to stay reachable for as long as the buyer may look at it. Send either this or a file; with neither you get no_invoice (400).

Accepts Any valid absolute URL

filefileoptionalThe invoice itself, sent as multipart/form-data rather than JSON. Takes precedence over url when both are sent. Stored on the same disk as a dashboard upload.

Accepts pdf · png · jpg · jpeg

Not supported Any other extension is rejected with invalid_invoice_type (400).

Example

{
    "url": "https://erp.example.com/invoices/FCT-2026-001.pdf"
}

Response#

FieldTypeDescription
order_idintegerThe order.
seller_invoicestringWhat was stored — the URL you gave us, or the path of the file you uploaded.

Example

{
    "order_id": 711,
    "seller_invoice": "https://erp.example.com/invoices/FCT-2026-001.pdf"
}

Failures use the shared error envelope — a machine-readable code and a request_id to quote to support. Error handling.
