summary: >-
  NewStore integrations are delivered through a documented catalog of outbound
  webhooks (provider/adapter callbacks) and an event stream. NewStore calls
  these endpoints on your infrastructure to request data or notify your systems
  of events. No standalone AsyncAPI document is published; this catalog captures
  the webhook surface verbatim from the API documentation.
