Go to your Mercado Pago account, navigate to **Developers > Your Integrations > Production Credentials** (or Sandbox), and copy your **Access Token**. It starts with 'APP_USR-' for production.

Can I generate Pix payments?

Yes! Use the `create_pix_payment` action. It generates a Pix transaction and returns QR Code data that can be displayed for the payer to scan and pay instantly.

Yes! Use the `refund_payment` action with a payment_id. If you omit the amount, it performs a full refund. If you provide an amount, it performs a partial refund.
