  CloudWalk publishes no AsyncAPI document for InfinitePay — /asyncapi.yaml and /asyncapi.json
  were probed on every host and the CloudWalk GitHub organization was searched, with no
  result. It does document a real, single-event webhook surface for the Integrated Checkout,
  captured here as a webhook catalogue. There is no webhook management API, no signature
  scheme, and no event-type envelope: the merchant supplies a webhook_url per checkout link
  and receives one POST when that link is paid.
delivery:
  transport: HTTPS POST
  content_type: application/json
  subscription: >-
    Per-link. The receiving URL is supplied as the optional `webhook_url` field on
    POST /links. There is no webhook registration endpoint and no account-wide endpoint
    configuration in the published API.
  acknowledgement:
    success: '200 OK'
    failure: '400 Bad Request'
    expected_latency: 'The reference asks receivers to respond in under ~1 second.'
  retries: >-
    Documented behaviour: responding 400 causes InfinitePay to attempt delivery again. The
    reference does not publish a retry schedule, a maximum attempt count or a backoff policy.
  signing: >-
    None published. The reference documents no signature header, no shared secret and no
    replay window. The reference's own guidance is to validate that the received `order_nsu`
    corresponds to a real order in your system.
  ordering: not specified
  idempotency: >-
    Not specified. Because retries are documented but delivery semantics are not, receivers
    should treat the webhook as at-least-once and de-duplicate on `transaction_nsu`.
events:
- name: payment_approved
  description: Sent when a payment against a checkout link is approved.
  trigger: Buyer completes payment on the InfinitePay-hosted checkout page.
  operation: openapi/cloudwalk-infinitepay-checkout-openapi.yml#/webhooks/paymentApproved
  payload:
  - {field: invoice_slug, type: string, description: The InfinitePay invoice code for the link.}
  - {field: amount, type: integer, description: Original amount in Brazilian cents.}
  - {field: paid_amount, type: integer, description: Amount actually paid in cents.}
  - {field: installments, type: integer, description: Number of installments.}
  - {field: capture_method, type: string, description: 'credit_card or pix'}
  - {field: transaction_nsu, type: string, description: Unique transaction identifier (UUID format).}
  - {field: order_nsu, type: string, description: The merchant order identifier supplied when the link was created.}
  - {field: receipt_url, type: string, description: Link to the buyer's payment receipt.}
  - {field: items, type: array, description: The items the link was created with (quantity, price, description).}
  example:
    invoice_slug: abc123
    amount: 1000
    paid_amount: 1010
    installments: 1
    capture_method: credit_card
    transaction_nsu: UUID
    order_nsu: UUID-do-pedido
    receipt_url: https://comprovante.com/123
    items:
    - {quantity: 1, price: 1000, description: Produto de Exemplo}
polling_alternative:
  description: >-
    The documented pull-based alternative to the webhook, for merchants that cannot expose a
    public endpoint.
  operation: openapi/cloudwalk-infinitepay-checkout-openapi.yml#checkPaymentStatus
  endpoint: POST https://api.checkout.infinitepay.io/payment_check
redirect_callback:
  description: >-
    Not a webhook, but the third documented completion signal: after paying, the buyer clicks
    "Continuar" and is returned to the merchant's `redirect_url` with query parameters.
  parameters: [receipt_url, order_nsu, slug, capture_method, transaction_nsu]
  caveat: >-
    Browser-supplied and therefore untrusted — the reference itself steers integrators toward
    the webhook or payment_check for confirmation.
gaps:
- No AsyncAPI or other machine-readable event contract.
- Single event type only; no refund, chargeback, dispute or settlement events published.
- No webhook signing or authentication mechanism published.
- No published retry schedule or delivery guarantees.
