Full list of events and their payload schemas. The Colossal app emits events when things happen in your project: orders placed, products published, payments processed. These events trigger [automations](/automations/overview). Some event payloads are privacy-safe snapshots. Customer name and email fields can be blank, and checkout payloads may omit shopper details when the event does not need them. Each event follows a consistent envelope format: The event type identifier Organization ID Project ID Primary entity identifier Type of entity (e.g. `"order"`, `"product"`, `"invoice"`) Event-specific payload (see below) Optional trace/correlation ID One of `"user"`, `"workflow"`, or `"system"` ISO 8601 UTC timestamp ### Orders Cart converted into an order during checkout, before payment.
