Lote de 1 000 facturas

A AEAT acepta ata 1 000 rexistros por envío. Este exemplo envía un lote completo e deixa que o SDK o trocee / respecte o TiempoEsperaEnvio entre chunks cando faga falta.

O script executable vive en examples/batch-1000/.

import { readFileSync } from 'node:fs';
import { VerifactuClient, Environment, type Invoice } from 'verifactu-sdk';

const client = new VerifactuClient({
  environment: Environment.Preproduction,
  mode: 'verifactu',
  certificate: {
    pfx: readFileSync('./cert.pfx'),
    passphrase: process.env.CERT_PASS ?? '',

});

function buildInvoice(index: number): Invoice {
  const seriesNumber = `BATCH/2026/${String(index).padStart(4, '0')}`;
  return {

    ],
    totalTaxAmount: '21.00',
    totalAmount: '121.00',
    generatedAt: new Date().toISOString(),
    billingSystem: {

    },
    chainLink: { first: index === 0 },
    hash: '',
  };
}

const invoices: Invoice[] = Array.from({ length: 1000 }, (_, i) => buildInvoice(i));

const responses = await client.registerInvoiceBatch(invoices);

for (const [idx, response] of responses.entries()) {
  console.log(`Chunk ${idx}: ${response.envelopeState} (${response.records.length} rexistros)`);
}

Que esperar

• O SDK trocea a lista en chunks de 1 000 (aquí non hai trocea — exactamente 1 000 rexistros).
• A cadea de pegadas mantense automaticamente: só o primeiro rexistro do primeiro chunk ten first: true.
• Cada chunk espera o TiempoEsperaEnvio da AEAT antes de despachar o seguinte.

Truco

Executa con VERIFACTU_DEBUG=1 para imprimir cada sobre e resposta a stderr:
