Offsite Pix payments

Updated: Nov 14, 2025
Payments API also enables businesses to collect payments from their customers via WhatsApp using dynamic Pix codes.
When using this integration, WhatsApp only facilitates the communication between merchants and buyers. Merchants are responsible for integrating with a bank or PSP in order to generate dynamic Pix codes, and confirm their payment.

Before you start

    Familiarize yourself with the Orders API. Orders are the entrypoint for collecting payments in WhatsApp.You will need an existing integration with a bank or PSP to generate dynamic Pix codes and do automatic reconciliation when a payment is made. You must be able to update the order status as soon as a payment is made.

    Integration steps

    The following sequence diagram shows the typical integration with Pix.
