PIX

PIX in MuPag starts as an authenticated charge and finishes through asynchronous confirmation.

What to store

• charge_id
• pix_emv_code
• expires_at
• request_id

Good practices

• Show the expiration time to the buyer.
• Treat paid, expired and canceled as distinct terminal states.
• In reconciliation, use charge_id and the webhook event as the source of truth.

If you only need to validate the technical path quickly, use the sandbox quick charge before wiring real checkout.
