User Attributes are pieces of information you know about a user which could be demographics like age or gender, account-specific like plan, or even things like whether a user has seen a particular A/B test variation. It's up to you!. It is basically a customer identity that you can reference across the customer’s whole lifetime.

Implementing Login/Logout

• It's important to set the User Attribute Unique ID when a user logs into your app.
• This is to merge the new user with existing user, if any exists, and will help prevent creating of unnecessary/stale users.
• Setting the Unique ID is a critical piece to tie a user across devices and installs/uninstalls as well across all platforms (i.e. iOS, Android, Windows, The Web). Set the USER_ATTRIBUTE_UNIQUE_ID attribute as soon as the user is logged in. Unique ID can be something like an email ID, a username (unique), or a database ID or any Backend generated ID.
• Do not set this for the user who not logged in.

Login User

import ReactMoE from 'react-native-moengage'
ReactMoE.setUserUniqueID("abc@xyz.com");

Logout User

import ReactMoE from 'react-native-moengage'
ReactMoE.logout();

Updating User Attribute Unique ID

In a scenario where you have to update the User Attribute Unique ID value for a logged in user use setAlias() method as shown below:

import ReactMoE from 'react-native-moengage'
ReactMoE.setAlias("asd@xyz.com");

Tracking User Attributes

Use the following helper methods to set User attributes like Name, Email, Mobile, Gender, etc.

import ReactMoE, {
  MoEGeoLocation,
} from "react-native-moengage";

ReactMoE.setUserName("abc");
ReactMoE.setUserFirstName("abc");
ReactMoE.setUserLastName("xyz");
ReactMoE.setUserEmailID("abc@xyz.com");
ReactMoE.setUserContactNumber(1234567890);
ReactMoE.setUserGender("Male"); // OR Female
// Format - ISO-8601 String
ReactMoE.setUserBirthday("1970-01-01T12:00:00Z");
// For Location use MoEGeoLocation instance
ReactMoE.setUserLocation(new MoEGeoLocation(77.3201, -77.3201));

For setting other User Attributes you can use the generic method setUserAttribute(key,value)

To set custom user attributes, you will have to provide the attribute name as shown below:

import ReactMoE, {
  MoEGeoLocation,
} from "react-native-moengage";

ReactMoE.setUserAttribute("attribute name", "attribute value");

// For Time attribute use ISO-8601 format
ReactMoE.setUserAttributeISODateString(
                  "time attribute name",
                  new Date().toISOString()
                );

// For Location, use MoEGeoLocation instance
ReactMoE.setUserAttributeLocation(
                  "location attribute name",
                  new MoEGeoLocation(10.3223, -88.6026)
                );
