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 update user attributes is right after the user logs into your application.

User ID Management

For optimal performance and data integrity:

• Update user information at login: It’s crucial to update the user information as soon as the user logs in.

• Unique userId: Ensure that each user has a unique userId. Assigning the same userId to multiple users leads to data inconsistencies and is not recommended.

SDK v4.5.0 Update: User Management Changes

As of version v4.5.0, 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:

let user = NetmeraUserIdentify()
user.userId = userId
user.email = email
user.msisdn = msisdn
Netmera.identifyUser(user)

Step 2: Update Profile Attributes

Use updateUserProfile to send user details:

let user = NetmeraUserProfile()
user.name.set("Muhammad Ali")
user.surname.set("Clay")
user.externalSegments.set(["sports", "boxing"])
user.gender.set(.male)
user.maritalStatus.set(.married)
user.numberOfChildren.set(9)
user.country.set("USA")
user.state.set("Kentucky")
user.city.set("Louisville")
user.district.set("West End")
user.occupation.set("Professional Boxer")
user.industry.set("Sports")
user.favoriteTeam.set("favoriteTeam")
user.language.set("English")
user.dateOfBirth.set(Date(timeIntervalSince1970: -915148800))
Netmera.updateUserProfile(userProfile: user)

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

let user = MyNetmeraUser()
user.externalSegments.set(["sports_fans","sports_fans"])
Netmera.updateUserProfile(userProfile: user)

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

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

2. add() – Add New Elements

let user = MyNetmeraUser()
user.externalSegments.add(["black_friday_2025"])
Netmera.updateUserProfile(userProfile: user)

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

let user = MyNetmeraUser()
user.externalSegments.remove(["sports_fans"])
Netmera.updateUserProfile(userProfile: user)

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

let user = MyNetmeraUser()
user.externalSegments.unset()
Netmera.updateUserProfile(userProfile: user)

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.

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 the KVKK law, the sharing of private user data is prohibited. To ensure compliance:

• Private Information Flag: When defining profile attributes or events, the Private Information feature must be selected to ensure that these attributes are not sent to the backend by the Netmera SDK.

• SDK Enforcement: The SDK checks for the Private Information flag during the Netmera.updateUser(user:) call. If the flag is set, the request will not be sent to the backend.

Fetch Coupon

Fetch coupons using the request/response structure and manager:

let filter = NetmeraCouponFilter(page: 1, max: 10)

Netmera.fetchCoupons(using: filter) { result in
    switch result {
    case .success(let coupons):
        print("Coupons fetched: \(coupons)")
    case .failure(let error):
        print("Error fetching coupons: \(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 { [weak self] result in
    DispatchQueue.main.async {
        switch result {
        case .success(let isEmailAllowed):
            self?.updateEmailToggle(isOn: isEmailAllowed)
        case .failure(let error):
            print("Failed to get email permission: \(error)")
        }
    }
}

• 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(isAllowed: true)

1. Disallow Email Subscriptions

Netmera.setEmailPermission(isAllowed: 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 { [weak self] result in
    DispatchQueue.main.async {
        switch result {
        case .success(let isSmsAllowed):
            self?.updateSmsToggle(isOn: isSmsAllowed)
            
        case .failure(let error):
            print("Failed to get SMS permission: \(error)")
        }
    }
}

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(isAllowed: true)

1. Disallow SMS Subscriptions

Netmera.setSmsPermission(isAllowed: 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

Netmera.setWhatsAppPermission(isAllowed: true)
Netmera.setWhatsAppPermission(isAllowed: false)

Check WhatsApp Subscription Status

Netmera.getWhatsAppPermission { result in
    self.whatsAppPermission = try? result.get()
}

Returns: true → The user allows WhatsApp messages false → The user does not allow WhatsApp messages
