User & Attributes

Managing User Data

The NetmeraUser class allows you to send structured information about your application's users to Netmera. The ideal time to manage user data is immediately after the user logs in.

User ID Management

For optimal performance and data integrity:

• Update at login: Always update the user identifiers immediately after the user logs in.

• Unique userId: Ensure every user is assigned a unique userId. Reusing the same ID across different users will result in data inconsistencies and is not supported.

SDK v4.4.0 Update: User Management Changes

As of version v4.4.0, the updateUser method has been deprecated. Use the following methods instead:

• identifyUser: Sets or updates identifiers such as userId, email, and msisdn.

• updateUserProfile: Updates user profile attributes like name, gender, birthday, occupation, etc.

Updating User Information

Step 1: Identify the User

Use identifyUser after the user logs in:

Kotlin

val user = NMUser()
user.setUserId("the_greatest")
user.setMsisdn("001XXXXXXXXX")
user.setEmail("[e-mail]")
Netmera.identifyUser(user)

Java

NMUser user = new NMUser();
user.setUserId("the_greatest");
user.setMsisdn("001XXXXXXXXX");
user.setEmail("[e-mail]");
Netmera.identifyUser(user);

Step 2: Update Profile Attributes

Use updateUserProfile to send user details:

Kotlin

val profile = NMUserProfile()
profile.name.set("Muhammad Ali")
profile.surname.set("Clay")
profile.externalSegments.set(listOf("sports", "box"))
profile.gender.set(Gender.MALE)
profile.maritalStatus.set(MaritalStatus.MARRIED)
profile.childCount.set(9)
profile.country.set("USA")
profile.state.set("Arizona")
profile.city.set("Scottsdale")
profile.district.set("Old Town Scottsdale")
profile.occupation.set("Professional Boxer")
profile.industry.set("Sports")
profile.favoriteTeam.set("My Team")
profile.language.set("English")
Netmera.updateUserProfile(profile)

Java

NMUserProfile profile = new NMUserProfile();
profile.getName().set("Muhammad Ali");
profile.getExternalSegments().set(Arrays.asList("sports", "box"));
profile.getGender().set(Gender.MALE);
profile.getMaritalStatus().set(MaritalStatus.MARRIED);
profile.getChildCount().set(9);
profile.getCountry().set("USA");
profile.getState().set("Arizona");
profile.getCity().set("Scottsdale");
profile.getDistrict().set("Old Town Scottsdale");
profile.getOccupation().set("Professional Boxer");
profile.getIndustry().set("Sports");
profile.getFavoriteTeam().set("My Team");
profile.getLanguage().set("English");
Netmera.updateUserProfile(profile);

Important Notes

• You should send a single user update request at a time.

• Do not use updateUser—it is deprecated and replaced by the two methods above.

Managing attributes with set, add, remove, and unset

The Netmera SDK supports four core operations for each profile attribute:

Operation	Description	Data Type
set()	Completely replaces the profile attribute	Available for all data types
unset()	Completely deletes the profile attribute	Available for all data types
add()	Adds new element(s) to the profile attribute	Available only for Array-type attributes
remove()	Removes specified element(s) from the profile attribute	Available only for Array-type attributes

For profile attributes defined as arrays, you do not need to manage the entire list at once. You can update them incrementally using add() and remove().

In the following examples, we use externalSegments, which is a predefined array-type profile attribute in the Netmera platform. However, you are free to define and use your own custom profile attributes as needed.

1. set() – Create List from Scratch

Kotlin

val profile = NMUserProfile()
val segments = listOf("sports_fans", "premium_subscriber")
profile.externalSegments.set(segments)
Netmera.updateUserProfile(profile)

Java

NMUserProfile profile = new NMUserProfile();
List<String> segments = Arrays.asList("sports_fans", "premium_subscriber");
profile.getExternalSegments().set(segments);
Netmera.updateUserProfile(profile);

Explanation: This operation clears any existing values in the externalSegments field and assigns the new list containing "sports_fans" and "premium_subscriber". Only the provided segments will be retained.

Use case: Reinitializing the user's profile with a new segment configuration.

2. add() – Add New Elements

Kotlin

val profile = NMUserProfile()
val segments = listOf("black_friday_2025")
profile.externalSegments.add(segments)
Netmera.updateUserProfile(profile)

Java

NMUserProfile profile = new NMUserProfile();
List<String> segments = Arrays.asList("black_friday_2025");
profile.getExternalSegments().add(segments);
Netmera.updateUserProfile(profile);

Explanation: Preserves existing values in the externalSegments list and appends the new segment "black_friday_2025".

Use case: Temporarily adding a user to a campaign-specific segment.

3. remove() – Remove Elements

Kotlin

val profile = NMUserProfile()
val segments = listOf("sports_fans")
profile.externalSegments.remove(segments)
Netmera.updateUserProfile(profile)

Java

NMUserProfile profile = new NMUserProfile();
List<String> segments = Arrays.asList("sports_fans");
profile.getExternalSegments().remove(segments);
Netmera.updateUserProfile(profile);

Explanation: Removes the "sports_fans" value from the user's externalSegments list. Other segment values remain unchanged.

Use case: Reflecting changes in user interests or preferences.

4. unset() – Clear All Data

Kotlin

val profile = NMUserProfile()
profile.externalSegments.unset()
Netmera.updateUserProfile(profile)

Java

NMUserProfile profile = new NMUserProfile();
profile.getExternalSegments().unset();
Netmera.updateUserProfile(profile);

Explanation: Clears all data from the externalSegments field. The user will no longer be associated with any segment.

Use case: When a user account is closed or profile data needs to be reset.

Important Note

To avoid update conflicts, ensure that only one profile update request is sent at a time.

To remove an attribute, set it to null:

Kotlin

val user = NMUser()
user.email = null
Netmera.identifyUser(user)

Java

NetmeraUser profile = new NMUser();
profile.setEmail(null);
Netmera.identifyUser(profile);

Removing Attributes With Unset

Kotlin

val profile = NMUserProfile()
profile.favoriteTeam.unset()
Netmera.updateUserProfile(profile)

Java

NMUserProfile profile = new NMUserProfile();
profile.getFavoriteTeam().unset();
Netmera.updateUserProfile(profile);

Creating Custom Profile Attributes

Step 1: Navigate to the Developers section

Custom profile attributes must be created and configured in the Netmera Panel before they can be used in the application.

• Go to Panel > Developers > Profile Attributes > Create New Attribute.

Step 2: Fill in Attribute Details

Define the following information:

• Name: The unique identifier for the attribute.

• Label: A user-friendly name for the attribute.

• Description: A brief description of the attribute.

• Data Type: Choose the appropriate data type for the attribute.

• Is Array: Define whether the attribute can hold multiple values.

Step 3: Save the Attribute

After clicking Save, the custom attribute will be available for assignment to your users.

Step 4: Generated Code for Custom Attributes

Once the attribute is defined in the Netmera Panel, the generated code can be found at the bottom of the Profile Attribute page, under the Generate Code section. This code must be added to your Netmera Panel under Profile Attributes > User Class.

Private Information Considerations

Under KVKK compliance:

• Mark profile attributes as Private Information in the panel if they are sensitive.

• If flagged, the SDK will not send these fields to the backend during identifyUser or updateUserProfile calls.

Fetching Coupons

Retrieve and display user-earned coupons:

Netmera.fetchCoupons(0, 10, object : NMFetchCouponsResultListener {
    override fun onSuccess(coupons: List<NMCouponDetail>?) {
        // Handle coupons
    }
    override fun onFailure(error: String?) {
        Toast.makeText(context, error ?: "No error message", Toast.LENGTH_SHORT).show()
    }
})

User Update with Listener

To track update status:

Netmera.updateUserProfile(profile, new NMUpdateUserProfileListener() {
    @Override
    public void onSuccess() {
        Log.i("NetmeraApp", "User updated successfully");
    }

    @Override
    public void onFailure(@Nullable String error) {
        Log.e("NetmeraApp", "Update failed: " + error);
    }
});

Email Subscription Preferences

The Netmera SDK provides methods to manage email subscription preferences for your users.

Check Email Subscription Status

Use the following method to check if the user has allowed email subscriptions:

Netmera.getEmailPermission()

• Returns: A Boolean value (true if the user has allowed email subscriptions, otherwise false).

Update Email Subscription Preferences

Set the user's preference for email subscriptions using one of the methods below:

1. Allow Email Subscriptions

Netmera.setEmailPermission(true)

1. Disallow Email Subscriptions

Netmera.setEmailPermission(false)

These methods enable you to respect user preferences for email communications within your application.

SMS Subscription Preferences

The Netmera SDK provides methods to manage SMS subscription preferences for your users.

Check SMS Subscription Status

Use the following method to check if the user has allowed SMS subscriptions:

Netmera.getSmsPermission()

Returns: A Boolean value (true if the user has allowed SMS subscriptions, otherwise false).

Update SMS Subscription Preferences

Set the user's preference for SMS subscriptions using one of the methods below:

1. Allow SMS Subscriptions

Netmera.setSmsPermission(true)

1. Disallow SMS Subscriptions

Netmera.setSmsPermission(false)

These methods enable you to respect user preferences for email communications within your application.

WhatsApp Subscription Preferences

Use these APIs to check or update whether the user allows receiving WhatsApp messages. This permission controls eligibility for WhatsApp-based campaigns.

Update WhatsApp Subscription Preference

// Set WhatsApp permission
Netmera.setWhatsAppPermission(true)
Netmera.setWhatsAppPermission(false)

Get WhatsApp Subscription Status

// Get WhatsApp permission
Netmera.getWhatsAppPermission(object : NMPermissionResultListener {

    override fun onSuccess(isAllowed: Boolean) {
        // Handle current WhatsApp permission state
    }

    override fun onFailure(error: String?) {
        // Handle error
    }
})
