Supported Personalization Tags

As a convenience, a summary of supported personalization tags are listed below. For more detail on each kind of tag and best practices, continue reading.

Most Recently Used Device Information

You can template in the following attributes for the user’s most recent device across all platforms. If a user has not used your application (e.g., you imported the user via REST API), then these values will all be null.

Because there are such a wide range of device carriers, model names, and operating systems, we advise that you thoroughly test any liquid that conditionally depends on any of those values. These values will be null if they are not available on a particular device.

Targeted Device Information

For push notification and in-app message channels, you can template in the following attributes for the device to which a message is being sent. That is, a push notification or in-app message can include device attributes of the device on which the message is being read. Note that these attributes will not work for Content Cards.

Because there are such a wide range of device carriers, model names, and operating systems, we advise that you thoroughly test any logic that conditionally depends on any of those values. These values will be null if they are not available on a particular device. Furthermore, for push notifications, it is possible that Braze may be unable to discern the device attached to the push notification under certain circumstances such as if the push token was imported via API, resulting in values being null for those messages.

In some circumstances, you may opt to use conditional logic instead of setting a default value. Conditional logic allows you to send messages that differ based on the value of a custom attribute.

Additionally, you can use conditional logic to abort messages to customers with null or blank attribute values.

For example, if you’re sending a rewards balance notification to customers, there isn’t a good way to account for customers with low and null balances using default values.

In this case, there are two options that may work better than setting a default value:

1. Abort the message for customers with low, null and blank balances.

   

2. Send a completely different message to these customers, perhaps something along the lines of:

1
2
3
4
5
{% if ${first_name} != blank and ${first_name} != null %}
Hello {{${first_name} | default: 'there'}}, thanks for downloading!
{% else %}
Thanks for downloading!
{% endif %}

In this example, a user with a blank or null first name will get the message “Thanks for downloading”. You should include a default value for first name to ensure that your customer does not see liquid in the event of a mistake.

Variable Tags

You can use the assign tag to create a variable in the message composer. Once you create a variable, you can reference that variable in your messaging logic or message.

Let’s say that you allow your customers to cash in their rewards points for prizes once they accrue 100 rewards points. So, you only want to message customers who would have a points balance above or equal to 100 if they made that additional purchase:

1
2
3
4
5
6
{% assign new_points_balance = {{custom_attribute.${current_rewards_balance} | plus: 50}} %}
{% if new_points_balance >= 100 %}
Make a purchase to bring your rewards points to {{new_points_balance}} and cash in today!
{% else %}
{% abort_message('not enough points') %}
{% endif %}

This tag comes in handy when you want to reformat content that is returned from our connected content feature. You can read more about variable tags here.

Iteration Tags

Iteration tags can be used to run a block of code repeatedly. This example features the for tag.

Let’s say that you’re having a sale on Nike sneakers and want to message customers who’ve expressed interest in Nike. You have an array of product brands viewed on each customer’s profile. This array could contain up to 25 product brands, but you only want to message customers who viewed a Nike product as one of their 5 most recent product views.

{% for items in {{custom_attribute.${Brands Viewed}}} limit:5 %}
{% if {{items}} contains 'Converse' %}
{% assign converse_viewer = true %}
{% endif %}
{% endfor %}
{% if converse_viewer == true %}
Sale on Converse!
{% else %}
{% abort_message() %}
{% endif %}

In this example, we check the first five items in the sneaker brands viewed array. If one of those items is converse, we create the converse_viewer variable and set it to true.

Then, we send the sale message when converse_viewer is true. Otherwise, we abort the message.

This is a simple example of how iteration tags can be used in Braze’s message composer. You can find more information here.

HTTP Status Codes

You can utilize the HTTP status from a Connected Content call by first saving it as a local variable and then using the __http_status_code__ key. For example:

1
2
3
4
{% connected_content https://example.com/api/endpoint :save connected %}
{% if connected.__http_status_code__ != 200 %}
{% abort_message('Connected Content returned a non-200 status code') %}
{% endif %}

{% alert tip %} Be aware that this key will only be automatically added to the Connected Content object if the endpoint returns a JSON object. If the endpoint returns an array or other type, then that key cannot be set automatically in the response. {% endalert %}

Sending Messages Based on Language, Most Recent Locale, and Time Zone

In some situations you may wish to send messages that are specific to particular locales. For example, Brazilian Portuguese is typically different than European Portuguese.

Here’s an example of how you can use most recent locale to further localize an internationalized message.

{% if ${language} == 'en' %}
Message in English
{% elsif  ${language} == 'fr' %}
Message in French
{% elsif  ${language} == 'ja' %}
Message in Japanese
{% elsif  ${language} == 'ko' %}
Message in Korean
{% elsif  ${language} == 'ru' %}
Message in Russian
{% elsif ${most_recent_locale} == 'pt_BR' %}
Message in Brazilian Portuguese
{% elsif ${most_recent_locale} == 'pt_PT' %}
Message in European Portuguese
{% elsif  ${language} == 'pt' %}
Message in default Portuguese
{% else %}
Message in default language
{% endif %}

In this example, customers with a most recent locale of ‘pt_BR’ will get a message in Brazilian Portuguese, customers with a most recent locale of ‘pt_PT’ will get a message in European Portuguese and customers who don’t meet the first two conditions but have their language set to Portuguese will get a message in whatever you’d like the default Portuguese language type to be.

You can also target users based off of their time zone. For example, send one message if they are based in EST and another if they are PST. To do this, save the current time in UTC, and compare an if/else statement with the user’s current time to ensure you’re sending the right message for the right timezone. You should set the campaign to send in the user’s local time zone, to ensure they are getting the campaign at the right time. See below for an example of how to write a message that will go out between 2PM and 3PM and will have a specific message for each time zone.

{% assign hour_in_utc = 'now' | date: '%H' | plus:0 %}
{% if hour_in_utc >= 19 && hour_in_utc < 20 %}
It is between 2:00:00pm and 2:59:59pm ET!
{% elsif hour_in_utc >= 22 && hour_in_utc < 23 %}
It is between 2:00:00pm and 2:59:59pm PT!
{% else %}
{% abort_message %}
{% endif %}
