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() API expects 2 parameters, event name, and event attributes i.e. instance of MoEProperties.  Add all the additional information which you think would be useful for segmentation while creating campaigns. For example, the following code tracks a 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 ReactMoE, {
  MoEGeoLocation,
  MoEProperties,
} from "react-native-moengage";
let properties = new MoEProperties();
properties.addAttribute("quantity", 1);
properties.addAttribute("product", "iPhone");
properties.addAttribute("currency", "dollar");
properties.addAttribute("price", 699);
properties.addAttribute("new_item", true);
properties.addAttribute("models", ["iPhone15", "iPhone14"]);
properties.addDateAttribute("purchase_date", "2020-06-10T12:42:10Z");
properties.addLocationAttribute(
  "store_location",
  new MoEGeoLocation(90.00001, 180.00001)
);
ReactMoE.trackEvent("Purchase", properties);
  • Event names should not contain any special characters other than ”_”. It can contain just spaces and an 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.
  • You can not use “user_id” to name custom attributes. It is a reserved system field, and using it might result in an error.

Analytics

MoEngage SDK tracks user sessions and application traffic sources.To learn more about how user session and application traffic source tracking works, refer to the following docs: 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 below 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 call setNonInteractive() of the MoEPropertiesinstance as shown below: 
import ReactMoE, {
  MoEGeoLocation,
  MoEProperties,
} from "react-native-moengage";
let properties = new MoEProperties();
properties.addAttribute("quantity", 1);
properties.addAttribute("product", "iPhone");
properties.addAttribute("currency", "dollar");
properties.addAttribute("price", 699);
properties.addAttribute("new_item", true);
properties.addAttribute("models", ["iPhone15", "iPhone14"]);
properties.addDateAttribute("purchase_date", "2020-06-10T12:42:10Z");
properties.addLocationAttribute(
  "store_location",
  new MoEGeoLocation(90.00001, 180.00001)
);
//Marking it as Non Interactive
properties.setNonInteractiveEvent();
ReactMoE.trackEvent("Purchase", properties);
