SDK adheres to the MoEngage FUP policies. For more information, refer to the Fair Usage Policy.
Tracking events is how you record any actions your users perform, along with any properties that describe the action. Every trackEvent call records a single user action. We recommend that you make your event names human-readable so that everyone on your team can know what they mean instantly. Every trackEvent() method call expects 3 parameters. They are the event name, event attributes and an account identifier. Event attributes use MoEProperties as an instance that represents attributes of the event. Add all the additional information which you think would be useful for segmentation while creating campaigns.
For example, the following code tracks an Purchase event of a product. We are including attributes like price, quantity, purchase date, and store location which describe the event we are tracking. 
import { MoECapacitorCore, MoEProperties } from 'capacitor-moengage-core'

const properties: MoEProperties = {
      generalAttributes: [
        { name: "quantity", value: 1 },
        { name: "product", value: "iPhone" },
        { name: "currency", value: "dollar" }
        { name: "price", value: 699 }
        { name: "new_item", value: "iPhone" }
      ],
      dateTimeAttributes: [
        { name: "purchase_date", value: "2020-06-10T12:42:10Z" }
      ],
      locationAttributes: [
        { name: "store_location", value: { latitude: 90.00001, longitude: 180.00001} }
      ]
};

MoECapacitorCore.trackEvent({ eventName: "Purchase", eventAttributes: properties, appId: "YOUR_WORKSPACE_ID"});
  • Event names should not contain any special characters other than ”_”. It can contain just spaces and underscore. Also, it should not contain “between”, “greater”, “less”, “in_the_last”, “in_the_next”, “equal”, “contains”, “starts”, or “is_not”.
  • You can not use “moe_” as a prefix while naming events, event attributes, or user attributes. It is a system prefix and using it might result in periodic blacklisting without prior communication.

​
Analytics

MoEngage SDK has started tracking user sessions and application traffic source. Refer to the Sessions in MoEngage Analytics and Source Analysis in MoEngage Analytics to learn more about how user session and application traffic source tracking works. With user session tracking we have introduced the flexibility to selectively mark events as non-interactive.

​
What is a non-interactive event?

Events that do not affect the session calculation in anyways are called non-interactive events. Non-interactive events have the following properties
  • Do not start a new session.
  • Do not extend the session.
  • Do not have information related to a user session.

​
How to mark an event as non-interactive?

To mark an event as a non-interactive set isNonInteractive property of the MoEProperties to true as shown below: 
import { MoECapacitorCore, MoEProperties } from 'capacitor-moengage-core'

const properties: MoEProperties = {
      generalAttributes: [
        { name: "quantity", value: 1 },
        { name: "product", value: "iPhone" },
        { name: "currency", value: "dollar" }
        { name: "price", value: 699 }
        { name: "new_item", value: "iPhone" }
      ],
      dateTimeAttributes: [
        { name: "purchase_date", value: "2020-06-10T12:42:10Z" }
      ],
      locationAttributes: [
        { name: "store_location", value: { latitude: 90.00001, longitude: 180.00001} }
      ],
      isNonInteractive: true
};

MoECapacitorCore.trackEvent({ eventName: "Purchase", eventAttributes: properties, appId: "YOUR_WORKSPACE_ID" });
