Tracking User Information

After you install SDK to your app, eSputnik begins automatically collect such data:

Information about push message delivery and openings,
Users’ push tokens,
Screen view events,
Statuses of the users’ subscription to push notifications.

eSputnik automatically creates user profiles with all these data, so you can immediately start working with new contacts, for example, sending them a mobile campaign.

When the user logs in or signs up to your app, you have to define a unique customer identifier that cannot be shared by other contacts. We call it External User Id or just User Id. The system will match all previous data with an external ID as the primary identifier and update the user’s profile.

External User ID

Add your custom External User Ids within eSputnik by the following method:

Reteno.updateUserAttributes(externalUserId: "USER_ID", attributes: UserAttributes)

When to send your user ID to eSputnik >

User Attributes

User attributes are attributes you define to describe segments of your user base, such as language preference or geographic location. Before sending specific contact data via API, you must add custom user fields to Reteno. Read more on how to set additional fields.

📘
Note
You can track user attributes only for users with external user IDs.

Add user attributes like phone, email, etc by the following method:

Reteno.updateUserAttributes(externalUserId: "USER_ID", userAttributes: UserAttributes, subscriptionKeys: [String], groupNamesInclude: [String], groupNamesExclude: [String])

📘
Note
groupNamesInclude and groupNamesExclude parameters are available in SDK version 1.0.0 or later.

The UserAttributes object structure:

public struct UserCustomField {
    let key: String
    let value: String
}

public struct Address {
    let region: String?
    let town: String?
    let address: String?
    let postcode: String?
}

public struct UserAttributes {
    let phone: String?
    let email: String?
    let firstName: String?
    let lastName: String?
    let languageCode: String?
    let timeZone: String?
    let address: Address?
    let fields: [UserCustomField]
}

phone
We use Google's libphonenumber library for phone number validation. Send phone numbers in the E164 format. A request with an invalid phone number will not be transmitted. You can validate phone numbers by the link.
languageCode
Data about language in RFC 5646 format. Primary language subtag in ISO 639-1 format is required. Example: de-AT
timeZone
Item from TZ database. Example: Europe/Kyiv

Anonymous User Attributes

Reteno SDK allows tracking anonymous user attributes. To start tracking information about user without identificator, use updateAnonymousUserAttributes() method:

let attributes = AnonymousUserAttributes(
    firstName: user.firstName,
    lastName: user.lastName,
    timeZone: TimeZone.current.identifier,
    fields: [
        UserCustomField(key: "LIST_NAME.FIELD_NAME", value: "Ukraine")
    ]
)
Reteno.updateAnonymousUserAttributes(userAttributes: attributes)

📘
Note
You can't provide to the SDK anonymous user phone and email attributes.

Multi-account Support

Since 2.5.11 it is possible to share push notification token between user accounts.

If it is required to receive push notifications on accounts that aren't currently logged in,
but they share the same device, use the updateMultiAccountUserAttributes method.

/// Update MultiAccount User attributes
  /// - Parameter externalUserId: Id for identify user in a system (optional)
  /// - Parameter userAttributes: user specific attributes in format UserAttributes (firstName, phone, email, etc.) (optional)
  /// - Parameter subscriptionKeys: list of subscription categories keys, can be empty
  /// - Parameter groupNamesInclude: list of group ID to add a contact to, can be empty
  /// - Parameter groupNamesExclude: list of group ID to remove a contact from, can be empty
  /// - Parameter accountSuffix: account suffix which will be used in deviceId. Usually accepts external user ID
  public static func updateMultiAccountUserAttributes(
    externalUserId: String? = nil,
    userAttributes: UserAttributes? = nil,
    subscriptionKeys: [String] = [],
    groupNamesInclude: [String] = [],
    groupNamesExclude: [String] = [],
    accountSuffix: String? = nil
  )
