spec_type: Webhooks
note: >-
  Paysend Enterprise delivers payout outcomes through configurable webhook
  notification (backward notification) callbacks rather than a published AsyncAPI
  document. Notification URLs are supplied in the request; Paysend calls back
  with the transaction outcome. No AsyncAPI/asyncapi.yaml is published.
transport: https
configuration:
  style: per-request callback URL
  fields:
    uri: The notification URL to call back (e.g. "https://example.com").
    method: HTTP method for the callback (e.g. "get").
  note: >-
    Notification endpoints are configured on the request via a uri + method
    pair. Paysend calls the endpoint when the transaction status changes.
payload_formats:
  basic:
    description: Minimal callback carrying only the transaction identifier.
    example_field: transactionId (UUID, e.g. "B8719542-fav4-4902-ab2c-11de595ace30")
  expanded:
    description: Full status-update callback.
    fields:
      - webhookType   # e.g. "TransactionStatusUpdate"
      - invoiceId
      - transactionId
      - status        # e.g. "Completed"
      - statusDateTime
      - errorCode
      - errorDescription
events:
  - type: TransactionStatusUpdate
    description: Sent when a payout transaction changes status.
    status_values_documented: [Completed]
    note: >-
      The webhook example documents the "Completed" status; the full status
      vocabulary is described under the /statuses/ reference
      (request/task statuses and result codes). See conventions/ and errors/.
verification:
  note: >-
    The developer portal's authentication guidance describes X-OPP-Signature
    verification for the API surface; the webhook page itself does not restate a
    signature mechanism. Confirm callback verification details with Paysend
    during onboarding.
