Setting Custom Attributes

Braze provides methods for assigning attributes to users. You’ll be able to filter and segment your users according to these attributes on the dashboard.

Before implementation, be sure to review examples of the segmentation options afforded by custom events vs. custom attributes vs. purchase events in our Best Practices section.

User attributes can be assigned to the current IAppboyUser. To obtain a reference to the current IAppboyUser, call Appboy.SharedInstance.AppboyUser

Assigning Standard User Attributes

The following attributes should be defined as properties of the IAppboyUser:

• FirstName
• LastName
• Email
• Gender
• DateOfBirth
• Country
• HomeCity
• PhoneNumber
• FacebookData
• TwitterData

Example Implementation

1
Appboy.SharedInstance.AppboyUser.FirstName = "User's First Name"

Assigning Custom User Attributes

Beyond the attributes above, Braze also allows you to define custom attributes using a number of different data types: For more information regarding the segmentation options, and how each of these attributes will affect you, see our “Best Practices” documentation within this section.

Setting Custom Attribute Values

• Boolean
• Integer
• Double/Float
• String
• Long
• Date
• Array

1
bool SetCustomAttribute(STRING_KEY, BOOL_VALUE);

1
bool SetCustomAttribute(STRING_KEY, INT_VALUE);

1
bool SetCustomAttribute(STRING_KEY, DOUBLE_VALUE);

1
bool SetCustomAttribute(STRING_KEY, "STRING_VALUE");

1
bool SetCustomAttribute(STRING_KEY, LONG_VALUE);

1
bool SetCustomAttribute(STRING_KEY, "DATE_VALUE");

// Setting a custom attribute with an array value
Appboy.SharedInstance.EventLogger.SetCustomAttributeArray("custom_attribute_array_test", testSetArray);
// Adding to a custom attribute with an array value
Appboy.SharedInstance.EventLogger.AddToCustomAttributeArray("custom_attribute_array_test", testAddString);
// Removing a value from an array type custom attribute
Appboy.SharedInstance.EventLogger.RemoveFromCustomAttributeArray("custom_attribute_array_test", testRemString);

Incrementing/Decrementing Custom Attributes

This code is an example of an incrementing custom attribute. You may increment the value of a custom attribute by any positive or negative integer value.

1
bool IncrementCustomAttribute(STRING_KEY, INCREMENT_INTEGER_VALUE);

Unsetting a Custom Attribute

Custom attributes can also be unset using the following method:

1
bool UnsetCustomAttribute(STRING_KEY);

Setting a Custom Attribute via the REST API

You can also use our REST API to set user attributes. To do so refer to the user API documentation.

Custom Attribute Value Limits

Custom attribute values have a maximum length of 255 characters; longer values will be truncated.

Managing Notification Subscription Statuses

To set up a subscription for your users (either email or push), you can set the subscription statuses below as properties of the IAppboyUser. Subscription statuses in Braze have three different states for both Email and Push:

• EmailNotificationSubscriptionType
  • Users will be set to Subscribed automatically upon receipt of a valid email address, however, we suggest that you establish an explicit opt-in process and set this value to OptedIn upon receipt of explicit consent from your user. Visit our Managing User Subscriptions doc for more details.
• PushNotificationSubscriptionType
  • Users will be set to Subscribed automatically upon valid push registration, however, we suggest that you establish an explicit opt-in process and set this value to OptedIn upon receipt of explicit consent from your user. Visit our Managing User Subscriptions doc for more details.

These types fall under AppboyPlatform.PCL.Models.NotificationSubscriptionType
