Update a series

Partially update a series: only the fields you send change (name, code, counter_reset, number_format, initial_number, invoice_kind; year_reset is the deprecated alias of counter_reset).

The same fiscal guards as the web app apply, each one as a 422 business_rule_violation with its own subcode and nothing changed: code and number_format only while the series has no documents (series_code_immutable_with_documents, series_format_immutable_with_documents); once AEAT has accepted a record of one of its invoices, code, number_format and initial_number are locked (series_locked_by_verifactu); initial_number cannot open a gap (series_initial_number_creates_gap); invoice_kind is fixed with the first invoice (series_invoice_kind_locked) and the default series of a purpose cannot change purpose (series_default_kind_change).
A code already used by another series of the same document type returns 422 with param=code; document_type cannot be changed.
Returns 200 with the updated series, and 404 series_not_found if it does not belong to your company.

Path Parameters

series*string

Headers

Idempotency-Key?string

Client-generated opaque key (up to 255 characters; UUID v7 recommended) that makes retries safe: the first response is cached and replayed for repeats without re-executing the mutation. Reusing a key with a different body returns 409 idempotency_key_reused. See the Idempotency guide.

Length1 <= length <= 255

Factuarea-Version?string

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.

Formatuuid

Request Body

application/json

TypeScript Definitions

Use the request body type in TypeScript.

name?string

Series name (1-100 characters).

Length1 <= length <= 100

code?string

Series prefix (1-10 characters: letters, digits, - and _). Editable only while the series has no documents (series_code_immutable_with_documents); it cannot repeat the code of another series of the same document type.

Match^[A-Za-z0-9\-_]+$

Length1 <= length <= 10

counter_reset?string

Counter reset policy: never, annual or monthly (monthly requires the {MM} token in the mask). Prospective change: numbers already issued are not renumbered.

Value in"never" | "annual" | "monthly"

year_reset?boolean

DEPRECATED: boolean alias of counter_reset (true = annual, false = never). counter_reset wins when both are sent.

number_format?string

Numbering mask (e.g. {code}-{YYYY}-{000}). Editable only until the first document is issued (series_format_immutable_with_documents).

Lengthlength <= 32

initial_number?integer

Initial counter number (>= 1). With documents in the current year it cannot leave a gap (series_initial_number_creates_gap).

Range1 <= value

invoice_kind?string

Purpose of an invoice series: complete, simplified, corrective or simplified_corrective. Fixed once the series has invoices (series_invoice_kind_locked).

Value in"complete" | "simplified" | "corrective" | "simplified_corrective"

document_type?string

Not accepted: the document type of a series cannot be changed.
