Update Vendor Bill

PATCH /accounting/vendor-bills/{id}

Group: Accounting › Vendor Bills · Operation ID: updateVendorBill

Updates the vendor bill with the given identifier. Only the fields in the request body change.

Only the fields in the request body change. Lines change through three arrays, applied in the order delete, then update, then create in one transaction, so one call can retire a line and add its replacement. updateLines and deleteLines address lines by the id the bill publishes, and a line id belonging to another bill is refused with LINE_NOT_FOUND. Omit all three to leave the lines untouched. currency governs the amounts on any line the call writes, and the stored currency is used when it is omitted. The response is empty. Read the record with GET accounting/vendor-bills/:id.

Parameters

Name In Type Required Description
Api-Version header "v1" yes The API version this request targets, named by its public identifier. Required on every request; omitting it, or naming a version this company does not have, is answered with 400. This document describes version v1.
Idempotency-Key header string no An opaque caller-chosen string (1-255 characters) that makes this request safe to retry. Repeating the same key with an identical request body replays the original response instead of re-executing - but only once that original request succeeded; a failed attempt re-executes on retry. Repeating the key with a different body is answered with 422. A key still in flight is answered with 409 - as is a key whose original request was interrupted before it finished, for a few minutes afterwards, until that attempt is presumed dead. A completed response stays replayable for 24 hours. The key is scoped to the caller, not to the action: reusing it for a different action is answered with 409 or 422 rather than treated independently. On read actions this header is ignored. On write actions that cannot offer the guarantee it is answered with 400 IDEMPOTENCY_NOT_SUPPORTED rather than silently ignored.
id path string yes The unique identifier for the vendor bill to update.
