Find an invoice by number

Looks up a single invoice by its number.

A number can repeat for two independent reasons — series recycle numbering across fiscal years, and two series of the same company each issue their own F-2026-001 — so both year and series_id are accepted as optional discriminators.
Returns 404 if not found, and 422 if the number still matches more than one invoice; the error message enumerates the series found (with their identifier) and the fiscal years, so that a second request can resolve it.

Pin the API version (YYYY-MM-DD, Stripe-style date versioning) for this request; omit to use the key's pinned version, or the latest if none. Unsupported version → 400 unsupported_api_version; malformed → 400 parameter_invalid_format. The effective version is echoed in the Factuarea-Version response header. See the Versioning guide.

Formatdate

X-Active-Profile?string

Operate on behalf of a child company (gestoría master key): pass its public id (UUID v7) and the request runs against that child's data without changing the key's scope, tier or environment (omit to use the key's own company). Invalid UUID → 400 parameter_invalid_uuid; unknown or non-owned id → 404 profile_not_found. See the Acting on behalf guide.
