Create a PIX charge with your SDK

Choose your language and call mupag.charges.create or the equivalent SDK method:

Installationnpm install mupag-sdk@0.2.0

import { MuPag } from 'mupag-sdk';

const mupag = new MuPag({
  apiKey: process.env.MUPAG_API_KEY,
  env: 'test',
});

const charge = await mupag.charges.create({
  amount_cents: 1290,
  payment_method: 'pix',
  customer: {
    name: 'Ana Silva',
    email: 'ana@example.com',
    tax_id: '12345678909',
  },
}, { idempotencyKey: 'order_123_charge_1' });

console.log(charge.charge_id);

Keep the secret key on the backend. The SDK generates an Idempotency-Key; for distributed retries, provide and persist one stable key for the same intent.

Public artifacts and source

• Public OpenAPI for generation and validation
• Postman collection published on this portal, limited to the public OpenAPI, with no filled-in secrets
• llms.txt and llms-full.txt for AI tooling
• Source, tests, examples, and releases for the Go and PHP SDKs in their dedicated public repositories

The remaining source and issue trackers stay internal. Public metadata points to this documentation, and the Java POM keeps the private SCM allowed by Maven Central while using this public portal as its project URL.

When you mention a package

Always use the coordinate and version shown on this page. Do not replace pinned versions with latest in production or agent configurations.
