  title: Efí Pix Webhook Setup
  summary: Register a Pix webhook for a Pix key and verify it was stored.
  description: >-
    Stands up payment notifications for an Efí Pay Pix key. The workflow
    authenticates, configures (PUT) the webhook callback URL for the supplied
    Pix key, then reads the webhook back to confirm Efí stored the same callback
    URL. Use this once per Pix key so settlement events are delivered to your
    endpoint. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
