Every order: charged, invoiced, shipped, notified.

// Prerequisites: CODESPAR_API_KEY set to a test key (csk_test_…), a Pix
// provider (Asaas, for instance) and Melhor Envio connected to the project.
// NFe.io and Z-API have no test environment: codespar_invoice (NF-e) and
// codespar_notify (WhatsApp) need a live key, and then issue and send for real.
import { CodeSpar } from "@codespar/sdk";

const session = await new CodeSpar().create("user_0000", { preset: "brazilian" });
const buyer = { name: "Ana Souza", email: "ana@example.com", document: "12345678909", phone: "+5511999990000" };

// 1 · charge the order by Pix (amount in reais)
const charge = await session.charge({ amount: 219.8, currency: "BRL", method: "pix", description: "Order #4821", buyer });
console.log(charge.status, charge.pix_copy_paste);

// 2 · buy the shipping label at Melhor Envio
const label = await session.ship({
  action: "label",
  origin: { postal_code: "01310-100" },
  destination: { postal_code: "20040-002" },
  items: [{ description: "Order #4821", weight_g: 800, width_cm: 15, height_cm: 10, length_cm: 20 }],
});
console.log(label.status, label.tracking_code);

Example with the published SDK (@codespar/sdk 0.16.11). Its prerequisites are in the comments. Compiling does not prove the integration: run it in test mode first.
