Void an invoice

Withdraw an issued invoice.

The invoice moves to annulled, voided_at starts reporting when that happened and the status is terminal: voiding is irreversible and there is no way back to sent or draft.
Void or correct? Void when the whole document should never have existed and has not been paid — the invoice is withdrawn as a whole and no amending document is produced.
Issue a corrective (POST /v1/invoices/{id}/corrective) when the invoice was already paid, or when only part of it is wrong (amount, recipient, partial return): a paid invoice can never be voided, and voiding never fixes a figure.
What voiding does not do: the correlative number of the series is neither released nor reused (the series counter only moves forward), the original invoice is not deleted, and its VeriFactu alta record is not withdrawn.
When the company is enrolled in VeriFactu, an AEAT cancellation (anulación) record is queued asynchronously with your reason as its motivo — a 200 means the invoice is annulled on our side, not that AEAT has already processed the cancellation.
With VeriFactu inactive the annulment is purely internal.
Limits: only an invoice in sent or overdue can be voided.
A draft is not voidable (delete it instead), and paid, cancelled and annulled return 422. An invoice that is a corrective can never be voided — to undo a wrong corrective, issue a new corrective of the original.
Note the inverse is allowed: having correctives does not block voiding the original.
Call GET /v1/invoices/{id}/can-annul first if you need to check eligibility without attempting the change.
reason is optional here and a placeholder is persisted when you omit it.
POST /v1/invoices/{id}/annul is the very same operation with reason required — prefer it whenever the reason must be documented.

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. Required on this operation: repeating it delivers an effect that cannot be taken back (an email sent, a file generated, a third-party call, a charge), so a request without this header is rejected with 422 idempotency_key_required before any business logic runs.

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.
