Conditional Messaging Logic (Tags)

Tags allow you to include programming logic in your messaging campaigns.

A tag must be wrapped in {% %}.

Tags can be used for executing conditional statements as well as for advanced use cases, like assigning variables or iterating through a block of code.

Conditional Logic

You can include many types of intelligent logic within messages – one example is a conditional statement. See the following example which uses conditionals to internationalize a campaign:

1
2
3
4
5
6
7
8
9
{% if ${language} == 'en' %}
This is a message in English from Braze!
{% elsif ${language} == 'es' %}
Este es un mensaje en español de Braze !
{% elsif ${language} == 'zh' %}
这是一条来自Braze的中文消息。
{% else %}
This is a message from Braze! This is going to go to anyone who did not match the other specified languages!
{% endif %}

Conditional Logic: Step By Step

In this example, we use tags with “if”, “elsif” and “else” statements to deliver internationalized content.

1
2
{% if ${language} == 'en' %}
This is a message in English from Braze!

If the customer’s language is English, the first condition is met and the customer will receive a message in English.

{% elsif ${language} == 'es' %}
Este es un mensaje en español de Braze !
{% elsif ${language} == 'zh' %}
这是一条来自Braze的中文消息。

You can specify as many conditional statements as you’d like- subsequent conditions will be checked if the previous conditions are not met. In this example, if a customer’s device is not set to English this code will check to see if the customer’s device is set to Spanish or Chinese. If the customer’s device meets one of these conditions, the customer will receive a message in the relevant language.

1
2
{% else %}
This is a message from Braze! This is going to go to anyone who did not match the other specified languages!

You have the option to include an {% else %} statement in your conditional logic. If none of the conditions that you set are met, the {% else %} statement specifies the message that should send. In this case, we default to English if a customer’s language is not English, Spanish or Chinese.

1
{% endif %}

The {% endif %} tag signals that you’ve finished your conditional logic. You must include the {% endif %} tag in any message with conditional logic. If you do not include an {% endif %} tag in your conditional logic, you’ll get an error as Braze will be unable to parse your message.
