How it works

From QR to webhook.

One flow, from receipt to confirmation, with an event for every change.

  1. 01

    Charge

    You create the charge through the API and receive the QR or the payment link.

  2. 02

    Payment

    The customer pays the PIX. Confirmation reaches the gateway in real time.

  3. 03

    Confirmation

    The charge status is updated and available in the API and the dashboard.

  4. 04

    Webhook

    A signed webhook notifies your application on every status change.

Developers

Built for your dev team.

Integrate PIX in a handful of REST calls, with predictable responses, clear error messages and a sandbox isolated from production.

  • Straightforward docs

    Quickstart, API reference and ready-to-copy examples.

  • Responsive REST API

    Predictable responses and clear errors, no guessing what went wrong.

  • Sandbox environment

    Isolated from production, with its own credentials.

  • Direct support

    A channel with people who know the integration, not a generic queue.
