type: Webhooks
summary: >-
  Wompi's only asynchronous surface is outbound webhooks ("Eventos") - server-to-server
  HTTP POST callbacks to a merchant-configured Events URL (set per environment in the
  Commerce Dashboard). There is no streaming / SSE / WebSocket transport, so no AsyncAPI
  document is authored; this is the documented webhook catalog. Each event is
  integrity-validated with an asymmetric SHA256 checksum carried both in the
  X-Event-Checksum HTTP header and in the event body's signature.checksum field.
transport: webhook
method_http: POST
config: Set an Events URL per environment (Sandbox and Production) in the Commerce Dashboard.
delivery:
  expected_response: HTTP 200
  retries: Up to 3 retries over 24h (at ~30 minutes, ~3 hours, and ~24 hours) on non-200.
signature:
  header: X-Event-Checksum
  algorithm: SHA256
  method: >-
    Concatenate the values of the fields listed in signature.properties (in order),
    then the signature.timestamp (UNIX), then the events/integrity secret from the
    Commerce Dashboard; SHA256 the concatenation and compare to signature.checksum.
  body_field: signature.checksum
envelope:
  event: string
  data: object
  sent_at: ISO-8601 timestamp
  signature:
    properties: array of field paths hashed
    timestamp: UNIX integer
    checksum: SHA256 hex string
  environment: test | prod
