Tracking User Information

After you install the SDK to your app, Reteno 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.

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

External User ID

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.

User Attributes

User attributes are attributes you define to describe segments of your user base, such as language preference or geographic location.

Add your custom External User Id and user attributes like phone, email, etc by the following method:

RetenoSDK.SetUserAttributes(string externalUserId, User user);

📘
Note
ExternalUserId must not be null or empty

User model:

{
   "UserAttributes":{
      "Phone":"string",
      "Email":"string",
      "FirstName":"string",
      "LastName":"string",
      "LanguageCode":"string",
      "TimeZone":"string",
      "Address":{
         "Region":"string",
         "Town":"string",
         "Address":"string",
         "Postcode":"string"
      },
      "Fields":[
         {
            "Key":"string",
            "Value":"string"
         },
         {
            "Key":"string",
            "Value":"string"
         }
      ]
   },
   "subscriptionKeys":[
      "string1",
      "string2"
   ],
   "groupNamesInclude":[
      "string1",
      "string2"
   ],
   "groupNamesExclude":[
      "string",
      "string2"
   ]
}

The structure of models (all fields are optional):

public class User
{
	public UserAttributes UserAttributes { get; set; }
	public List<string> SubscriptionKeys { get; set; }
	public List<string> GroupNamesInclude { get; set; }
	public List<string> GroupNamesExclude { get; set; }
}

public class UserAttributes
{
	public string Phone { get; set; }
	public string Email { get; set; }
	public string FirstName { get; set; }
	public string LastName { get; set; }
	public string LanguageCode { get; set; }
	public string TimeZone { get; set; }
	public UserAddress Address { get; set; }
	public List<Field> Fields { get; set; }
}

public class UserAddress
{
	public string Region { get; set; }
	public string Town { get; set; }
	public string Address { get; set; }
	public string Postcode { get; set; }
}

public class Field
{
	public string Key { get; set; }
	public string Value { get; set; }
}

Anonymous User Attributes

Reteno SDK allows tracking anonymous user attributes (no externalUserId required). To set user attributes without externalUserId use method SetAnonymousUserAttributes(User user):

RetenoSDK.SetAnonymousUserAttributes(User user);

📘
Note
You can't provide anonymous user attributes with phone or/and email. For that purpose use SetUserAttributes() method with externalUserId
