Use initializeCustomer whenever a user logs in, registers, or you need to refresh their profile. This lets Gameball attach events, rewards, and notifications to the correct customer.
Before calling initializeCustomer, make sure you have already initialized the SDK using Initialize SDK.

​
Basic Customer Initialization

val customerRequest = InitializeCustomerRequest.builder()
    .customerId("customer-123")
    .email("customer@example.com")
    .mobileNumber("+1234567890")
    .deviceToken("fcm-device-token")
    .pushProvider(PushProvider.Firebase)
    .build()

GameballApp.getInstance(context).initializeCustomer(
    customerRequest,
    object : Callback<InitializeCustomerResponse> {
        override fun onSuccess(response: InitializeCustomerResponse) {
            // Customer initialized successfully
        }

        override fun onError(error: Throwable) {
            // Handle error
        }
    }
)

// With session token override
GameballApp.getInstance(context).initializeCustomer(
    customerRequest,
    callback,
    sessionToken = "custom-token"
)
Call initializeCustomer immediately after a successful login or registration flow so the customer profile stays up to date.

Validation Rules

InitializeCustomerRequest requires:
  • customerId cannot be empty
  • If pushProvider is set, deviceToken is required
  • If deviceToken is set, pushProvider is required
Choose an Unchangeable Customer ID: customerId should be a permanent identifier that never changes.

​
Enriching Profiles with Customer Attributes

Use the CustomerAttributes builder to send richer profile data to Gameball. 
val attributes = CustomerAttributes.builder()
    .displayName("John Doe")
    .firstName("John")
    .lastName("Doe")
    .email("john@example.com")
    .mobileNumber("+1234567890")
    .gender("male")
    .dateOfBirth("1990-01-15")
    .joinDate("2024-01-01")
    .preferredLanguage("en")
    .channel("mobile")
    .addCustomAttribute("favoriteCategory", "electronics")
    .addAdditionalAttribute("segment", "premium")
    .addAdditionalAttribute("city", "New York")
    .addAdditionalAttribute("country", "USA")
    .build()

val customerRequest = InitializeCustomerRequest.builder()
    .customerId("customer-123")
    .email("john@example.com")
    .mobile("+1234567890")
    .customerAttributes(attributes)
    .referralCode("REF123")
    .isGuest(false)
    .build()
