Emet una factura

Emet una factura en esborrany sense enviar-la: li assigna el número definitiu de sèrie, congela les dades de l'emissor i del client, fixa issued_at, dona d'alta el registre VeriFactu quan correspon i emet l'esdeveniment invoice.issued.

No s'envia cap email ni es posa la marca d'enviament (is_sent continua en false); per lliurar-la fes servir POST /v1/invoices/{id}/send, o POST /v1/invoices/{id}/mark-sent amb Factuarea-Version: 2026-10-01 si la vas lliurar per un altre canal.
Només es pot emetre un draft: qualsevol altre estat retorna 422 invalid_status_transition.
Emetre és irreversible i consumeix un número de sèrie, així que envia un Idempotency-Key per reintentar amb seguretat.
Disponible a totes les versions de l'API; la resposta segueix la versió efectiva (abans de 2026-10-01 la factura emesa es publica com a status: sent).

Idempotency-Key*string

Clau opaca generada pel client (fins a 255 caràcters; es recomana UUID v7) que permet reintents segurs: la primera resposta s'emmagatzema i es reprodueix en les repeticions sense tornar a executar la mutació. Reutilitzar una clau amb un cos diferent retorna 409 idempotency_key_reused. Consulta la guia d'idempotència. Obligatòria en aquesta operació: repetir-la produeix un efecte irreversible (un correu enviat, un fitxer generat, una crida a un tercer o un càrrec), per la qual cosa una petició sense aquesta capçalera es rebutja amb 422 idempotency_key_required abans d'executar lògica de negoci.

Longitud1 <= length <= 255

Factuarea-Version?string

Fixa la versió de l'API (YYYY-MM-DD, versionat per data estil Stripe) per a aquesta petició; omet-lo per usar la versió fixada de la clau, o l'última si no n'hi ha cap. Versió no suportada → 400 unsupported_api_version; mal formada → 400 parameter_invalid_format. La versió efectiva es reflecteix a la capçalera de resposta Factuarea-Version. Consulta la guia de Versioning.

Formatdate

X-Active-Profile?string

Opera en nom d'una empresa filla (API key mestra de gestoria): passa el seu id públic (UUID v7) i la petició s'executa contra les dades d'aquella filla sense canviar l'scope, el tier ni l'environment de la clau (omet-lo per usar la pròpia empresa de la clau). UUID no vàlid → 400 parameter_invalid_uuid; id desconegut o no propi → 404 profile_not_found. Consulta la guia d'Acting on behalf.
