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

The application needs to notify the MoEngage SDK whenever the user is logged out of the application. To notify the SDK, call the API whenever the user is logged out of the application.

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

Updating User Attribute Unique Id

Use the method setAlias() to update the user attribute unique id instead of setUniqueId() with a different value. Using the method setUniqueId() with a new value creates unintended users in MoEngage.

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