Tracking Events

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() call expects 2 parameters, event name and event attributes using MoEProperties instance which represents additional information about the event. Add all the additional information which you think would be useful for segmentation while creating campaigns. For eg: 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.addDateAttribute("purchase_date", "2020-06-10T12:42:10Z");
properties.addLocationAttribute(
  "store_location",
  new MoEGeoLocation(90.00001, 180.00001)
);
ReactMoE.trackEvent("Purchase", properties);

🚧

Naming Restrictions

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”, “is_not".

Analytics

MoEngage SDK has started tracking user session 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 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 non-interactive call setNonInteractiveEvent method of the MoEProperties instance 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.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);

🚧

Minimum SDK Version

To use Session and Source Tracking you might have to update the native MoEngage Android and iOS SDKs
