+ * plugin:
+ *
+ * * **isRequestEcommerce**: If `true`, the request is for an ecommerce goal conversion.
+ *
+ *                           Set in `processRequestParams()`.
+ *
+ * * **isGoalAnOrder**: If `true` the request is tracking an ecommerce order.
+ *
+ *                      Set in `processRequestParams()`.
