  title: Event Subscriptions API
  version: 3.0.0
  description: '**BETA** - The Event Subscriptions API allows you to subscribe to parcel events and have them delivered to external endpoints such as webhooks or Klaviyo.


    This API uses a two-part model:

    - **Connections** define _where_ events are delivered (e.g., a webhook URL or a Klaviyo account).

    - **Subscriptions** define _which_ events are routed to a connection.


    All resources are scoped to the authenticated user''s organization.'
