Issue an invoice

Issues a draft invoice without sending it: assigns its definitive series number, freezes the issuer and customer snapshots, sets issued_at, registers the VeriFactu record when applicable and emits the invoice.issued event.

No email is sent and the delivery mark is not set (is_sent stays false); to deliver it use POST /v1/invoices/{id}/send, or POST /v1/invoices/{id}/mark-sent with Factuarea-Version: 2026-10-01 when you delivered it through another channel.
Only a draft can be issued: any other status returns 422 invalid_status_transition.
Issuing is irreversible and consumes a series number, so send an Idempotency-Key to retry safely.
Available in every API version; the response follows the effective version (before 2026-10-01 the issued invoice is published as status: sent).

Path Parameters

invoice*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. 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.

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.
