openUBL - Peruvian SUNAT Electronic Documents Library

Project description

openUBL

PyPI npm

Genera, firma y valida documentos electrónicos UBL 2.1 para SUNAT (Perú) — sin complicaciones.

openUBL es una biblioteca Python con API REST incluida. Genera XML válido para facturas, notas de crédito, notas de débito, comunicaciones de baja, resúmenes diarios, percepciones y retenciones. Firma digitalmente con XMLDSig (RSA-SHA-256 / SHA-256) y valida contra las reglas SUNAT antes de enviar.

¿Por qué openUBL?

  • Sin dependencias externas — todo en Python. No necesitas servicios de terceros para generar XML.
  • API REST lista para usar — levantas FastAPI y generas documentos vía HTTP.
  • SDK TypeScript — tipos generados desde OpenAPI, con autocompletado completo.
  • Firma digital integrada — firma con certificado PEM sin herramientas externas.
  • Validación SUNAT — detecta errores antes del envío, no después.
  • Documentación completa — guías paso a paso en https://darvin2c.github.io/openUBL

Instalación rápida

Python

pip install openubl
from openubl.models import Invoice, Proveedor, Cliente, DocumentoVentaDetalle
from openubl.renderer import render_invoice
from openubl.enricher import ContentEnricher

invoice = Invoice(
    serie="F001",
    numero=1,
    proveedor=Proveedor(ruc="20100066603", razonSocial="Softgreen S.A.C."),
    cliente=Cliente(nombre="Carlos", numeroDocumentoIdentidad="12121212121", tipoDocumentoIdentidad="6"),
    detalles=[DocumentoVentaDetalle(descripcion="Item", cantidad=10, precio=100)],
)

enricher = ContentEnricher()
enricher.enrich(invoice)

xml = render_invoice(invoice)
print(xml)  # XML UBL 2.1 listo para firmar

TypeScript / JavaScript

npm install @openubl/sdk
import { createInvoice, SDK_VERSION, checkApiVersion } from "@openubl/sdk";
import { zInvoice } from "@openubl/sdk/zod.gen";

const invoice = zInvoice.parse({
  serie: "F001",
  numero: 1,
  proveedor: { ruc: "20100066603", razonSocial: "Softgreen S.A.C." },
  cliente: { nombre: "Carlos", numeroDocumentoIdentidad: "12121212121", tipoDocumentoIdentidad: "6" },
  detalles: [{ descripcion: "Item", cantidad: 10, precio: 100 }],
});

const { data, error } = await createInvoice({ body: invoice });
if (error) throw new Error(JSON.stringify(error));
console.log(data.xml); // XML UBL 2.1 generado

Validación de versión

Verifica que tu SDK y la API compartan la misma versión:

from openubl.version import check_api_version

result = check_api_version("http://localhost:8000")
assert result["ok"], f"Desfase: SDK {result['sdk_version']} vs API {result['api_version']}"
import { checkApiVersion } from "@openubl/sdk";

const result = await checkApiVersion("http://localhost:8000");
if (!result.ok) throw new Error(`Desfase: SDK ${result.sdkVersion} vs API ${result.apiVersion}`);
