facturapi

FacturAPI

This is the official HTTP client for https://www.facturapi.io

FacturAPI makes it easy for developers to generate valid Invoices in Mexico (known as Factura Electrónica or CFDI).

If you've ever used Stripe or Conekta, you'll find FacturAPI very straightforward to understand and integrate in your server app.

Compatibility

• Node.js 12.x or higher
• Browsers with Fetch API support
• React Native

Install

npm install --save facturapi

Getting started

Authenticate with your API Key

Make sure you have created your free account on FacturAPI and that you have your API Keys.

// ES6
import Facturapi from 'facturapi';
// CommonJS
const Facturapi = require('facturapi').default;

const facturapi = new Facturapi('YOUR_API_KEY', {
  apiVersion: 'v2', // Optional, say what API version you want to use. Defaults to the latest version.
});

Create a customer

facturapi.customers
  .create({
    legal_name: 'Walter White', // Razón social
    tax_id: 'WIWA761018', // RFC
    email: '[e-mail]', // Optional but useful to send invoice by email
    address: {
      street: 'Av. de los Rosales',
      exterior: '123',
      neighborhood: 'Tepito',
      zip: '06800',
      // city, municipality and state are filled automatically from the zip code
      // but if you want to, you can override their values
      // city: 'México',
      // municipality: 'Cuauhtémoc',
      // state: 'Ciudad de México'
    },
  })
  .then((customer) => {
    // Remember to store the customer.id in your records.
    // You will need it to create an invoice for this customer.
  })
  .catch((err) => console.log(err)); // Handle the error.

Create a product

facturapi.products
  .create({
    product_key: '4319150114', // Clave Producto/Servicio from SAT's catalog. Log in to FacturAPI and use our tool to look it up.
    description: 'Apple iPhone 8',
    price: 20000, // price in MXN.
    // By default, taxes are calculated from the price with IVA 16%
    // But again, you can override that by explicitly providing a taxes array
    // taxes: [
    //   { type: Facturapi.TaxType.IVA, rate: 0.16 },
    //   { type: Facturapi.TaxType.ISR, rate: 0.03666, withholding: true }
    // ]
  })
  .then((product) => {
    // Remember to store the product.id in your records.
    // You will need it to create an invoice for this product.
  })
  .catch((err) => console.log(err)); // Handle the error.

Create an invoice

facturapi.invoices.create({
  customer: 'YOUR_CUSTOMER_ID',
  payment_form: Facturapi.PaymentForm.TRANSFERENCIA_ELECTRONICA, // Constant from SAT's catalog. Check out our documentation to learn more.
  items: [{
    quantity: 1, // Optional. Defaults to 1.
    product: 'YOUR_PRODUCT_ID' // You can also pass a product object instead
  }] // Add as many products as you want to include in your invoice
}).then(invoice => { ... });

Download your invoice

// Once you have successfully created your invoice, you can...
const fs = require('fs');
facturapi.invoices.downloadZip(invoice.id) // or downloadPdf or downloadXml
  .then(zipStream => {
    // stream containing the PDF and XML as a ZIP file
    // Save your invoice to a folder
    const myZipFile = fs.createWriteStream('/path/to/destination/folder');
    zipStream.pipe(myZipFile);
    myZipFile.on('finish', () => {
      // Finished downloading, Yay!
    });

Send your invoice by email

// Send the invoice to your customer's email (if any)
facturapi.invoices
  .sendByEmail(invioce.id) // Also returns a Promise
  .then(() => {
    // Successfully sent
  })
  .catch((err) => console.log(err)); // Handle the error.
