* The user selects Biometric PIX as the payment method.
* You submit the enrollment and payment details by simply setting the `payment_method` parameter to `IXB`.
* The user is redirected to the provided URL.
* One-time registration with their banking institution:
  * The user registers with the institution.
  * The institution requests biometric validation for confirmation.
  * The user validates their biometrics, and the institution stores the data for future payments.
* After registration, the user is redirected back to your application to complete the payment.
* The payment is authenticated via biometrics, and the user is redirected back to your application.\
  \
  \&#xNAN;*That's it! The entire enrollment and payment process requires just one POST call to our API - our PIX Biometric solution takes care of the rest.*
