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. User attributes vs. purchase events in our Best Practices section. You should also check out our notes on event naming conventions.

Assigning Standard User Attributes

User attributes will be assigned to the currently active user. The following default fields may be set:

• FirstName
• LastName
• Email
• Gender
• DateOfBirth
• Country
• Language
• HomeCity
• PhoneNumber
• AvatarImageUrl

Implementation Example
This is what setting a first name would look like in code:

1
m.Braze.setFirstName("User's First Name")

Assigning Custom User Attributes

Beyond the default attributes above, Braze also allows you to define custom attributes using several 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.

Settings Custom Attribute Values

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

1
m.Braze.setCustomAttribute("boolAttribute", true)

1
m.Braze.setCustomAttribute("intAttribute", 5)

1
m.Braze.setCustomAttribute("floatAttribute", 3.5)

1
m.Braze.setCustomAttribute("stringAttribute", "stringValue")

dateAttribute = CreateObject("roDateTime")
dateAttribute.fromISO8601String("1992-11-29 00:00:00.000")
m.Braze.setCustomAttribute("dateAttribute", dateAttribute)

stringArray = createObject("roArray", 3, true)
stringArray.Push("string1")
stringArray.Push("string2")
stringArray.Push("string3")
m.Braze.setCustomAttribute("arrayAttribute", stringArray)

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
m.Braze.incrementCustomUserAttribute("intAttribute", 3)

Unsetting a Custom Attribute

Custom atributes can also be unset using the following method:

1
m.Braze.unsetCustomAttribute("attributeName")

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.

Managing Email Subscription Status

You can set the following email subscription statuses for your users programmatically through the SDK.

These types fall under BrazeConstants().SUBSCRIPTION_STATES

The method for setting email subscription status is setEmailSubscriptionState(). 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.

Example usage:

1
m.Braze.setEmailSubscriptionState(BrazeConstants().SUBSCRIPTION_STATES.OPTED_IN)
