The React Native SDK surfaces a series of APIs allowing you to manage user-identity state. These client-side APIs work in tandem with mParticle’s Identity API and your configured Identity strategy. Identity management requirements vary by app, so it’s crucial that you use the APIs correctly per your requirements.
| Identity Type | Description |
|---|---|
customerid |
An internal customer ID in your app |
deviceapplicationstamp |
The ID for the user’s device generated by mParticle when the SDK initializes. Learn more in Device ID |
email |
The user’s email address |
facebook |
The user’s Facebook ID |
facebookcustomaudienceid |
The user’s Facebook Custom Audience ID |
google |
The user’s Google ID |
iosadvertiserid |
The user’s iOS advertiser ID |
iosvendorid |
The user’s iOS vendor ID |
microsoft |
The user’s Microsoft ID |
mobilenumber |
The user’s mobile phone number |
other |
The first of 10 possible custom identifiers that can help identify the user. Append a number from 2 to 10 for each identifier in addition to the first. For example, the second custom identifier would be other2. |
phonenumber2 |
The user’s second phone number |
phonenumber3 |
The user’s third phone number |
pushtoken |
An iOS APNS push token, Android FCM Instance ID, or Fire push token that can help identify the user |
twitter |
The user’s Twitter ID |
yahoo |
The user’s Yahoo ID |
The mParticle Identity APIs surface four key operations (identify, login, logout, and modify). identify is called automatically when the mParticle SDK is initialized. When using the React Native SDK, the initial request should be handled in your iOS or Android native code during SDK initialization. See our iOS and Android docs for more info on how to identify a user when the SDK initializes.
Once the SDK has initialized, you can use the login, logout and modify methods supported by the React Native SDK. Each method accepts an optional request object and a callback. Populating the request object correctly is crucial to managing the state of your users.
The IdentityRequest object is a holder for a set of identities that you would like to associate with the user. Populating the request object correctly is crucial to managing the state of your users. When you invoke any of the key Identity APIs with a request object, the identities it holds will be associated with the resulting user.
var request = new MParticle.IdentityRequest();
request.email = 'h.jekyll.md@example.com';The Identify API is treated specially in that it’s called automatically on SDK initialization by the mParticle SDK. The SDK requires this call to succeed in order to establish an identity to associate with all data.
Login and Logout should be invoked at the time of the user performing the matching or applicable actions in your application. These methods accept an Identity Request object and a callback, allowing you to handle errors, or do something with the returned User.
MParticle.Identity.login(request, (error, user) => {
if (error) {
console.debug(error);
} else {
console.debug(user.userAttributes);
}
});MParticle.Identity.logout(null, (error, user) => {
if (error) {
console.debug(error);
} else {
console.debug(user.userAttributes);
}
});Modify also has the identical signature, but note a crucial difference: modify actions will never result in a new user. Modify can only add, remove, or change the identities associated with an existing user. The mParticle SDK will compare the current user’s user identities with those that you supply within the IdentityApiRequest, in order to generate a delta and invoke the underlying Identity HTTP API.
In this example, the SDK will change the email of the current user, or add the email to the user’s profile if the user has no existing email on this device:
var request = new MParticle.IdentityRequest();
request.email = 'ed.hyde@example.com';
MParticle.Identity.modify(request, (error, apiResult) => {
if (error) {
console.debug(error);
} else {
console.debug(apiResult.user.userAttributes);
}
});Once the SDK has successfully called Identify for the first time, you will be able to access the current user via getCurrentUser():
MParticle.Identity.getCurrentUser((currentUser) => {
// Set user attribute
currentUser.setUserAttribute('Test key', 'Test value')
// Set reserved user attribute
currentUser.setUserAttribute(MParticle.UserAttributeType.FirstName, 'Test first name')
// Create an attribute list
currentUser.setUserAttributeArray('Test key', ['Test value 1', 'Test value 2'])
// Create a tag
currentUser.setUserTag('Test key')
// Remove an attribute
currentUser.removeUserAttribute('Test key')
});Always refer to your organization’s data plan when instrumenting user or event attributes. Each unique attribute key becomes a data point in the mParticle UI that can be filtered for each Output, used to drive the calculation of an Audience or become part of a Custom Mapping. This means that your choice of attribute keys can have a system-wide impact. For example, if you have a single attribute key per device that represents a unique User ID or a unique URL, and you have thousands of users, mParticle will see thousands of unique keys, even though you only create one per device.
Creating too many unique attribute keys can have several adverse effects:
You should avoid the following as attribute keys:
A gaming app has ten levels and you want to track which level each user has achieved.
Bad option: Create ten tags - reachedLevel1, reachedLevel2, reachedLevel3, etc.
Better option: Create a single attribute - reachedLevel = 4.
Capturing this data as a single attribute improves the performance of both your app and the mParticle dashboard by reducing the number of unique data points you need to manage. It’s also a much more useful data point. For example, you can easily create a single audience builder condition to target users within a range of levels reached.
An mParticle Workspace can combine data from multiple platforms, for example it can show data from the same app running in iOS and Android. For this reason, you may wish to choose attribute names that you can keep consistent across all platforms for easier management. For example, if you call an attribute levelReached in iOS, LevelReached on Android, and level_reached on web, mParticle will treat these as three separate attributes.
