Liquid templates

Play

Liquid templates significantly broaden Pushwoosh’s personalization capabilities by implementing sophisticated logic in addition to regular Dynamic Content usage.

Message personalization in Pushwoosh is based on Tags (user data). Pushwoosh offers a variety of default Tags and custom Tags. Using them, you can specify user’s first name, city, purchase history, etc. to send a more personalized message, for example: Hi {First_name}, thanks for ordering {item}.

Liquid templates add more logic to dynamic content. For instance, if a user’s subscription tag contains “free,” you can send them a message: “Grab your 10% discount.”

Modifying the message content according to users’ IDs, behaviors, and preferences is the most efficient way to increase relevance and get more impressive results from your marketing campaigns.

Syntax

Content templates based on Liquid by Shopify use a combination of tags, objects, and filters to load dynamic content. Content templates allow to access certain variables from within a template and output their data without having to know anything about the data itself.

Note

To learn more about the syntax, please refer to Liquid documentation.

Objects

objects define the content that will be displayed to a user. objects should be enclosed in double curly braces: {{ }}

For example, when personalizing a message, send {{Name}} in its body to add the users’ names to the message’s content. The user’s name (Name tag value) will replace the Liquid object in a message the user will see.

Input

Hi {{Name}}! We're glad you're back!

Output

Hi Anna! We’re glad you’re back!

Tags

tags create the logic and control flow for templates. The curly brace percentage delimiters {% and %} and the text that they surround do not produce any visible output when the template is rendered. This lets you assign variables and create conditions or loops without showing any of the Liquid logic to a user.

For example, using the if tag, you can vary the message’s language based on what language is set on user’s device:

Input:

{% raw %}
{% if Language == 'fr' %}
Salut!
{% else %}
Hello!
{% endif %}
{% endraw %}

Output (fr): Salut!

Output (es): Hello!

Tags operators

Operator	Description
==	equals
!=	does not equal
>	greater than
<	less than
>=	greater than or equal to
<=	less than or equal to
or	logical or
and	logical and
contains	checks for the presence of a substring inside a string or array of strings

Note

In tags with more than one and or or operator, operators are checked in order from right to left. You cannot change the order of operations using parentheses — parentheses are invalid characters in Liquid and will prevent your tags from working.

Filters

filters modify the output of a Liquid object or variable. They are used within double curly braces {{ }} and variable assignment, and are separated by a pipe character |. Multiple filters can be used on one output, and are applied from left to right.

Input	Output
{{ Name | capitalize | prepend:"Hello " }}	Hello Anna

Connected content

Connected content is a feature in Liquid templates that allows you to dynamically retrieve and use data from an external source, such as a web service, directly within your email or push notification templates. This feature enables real-time personalization by fetching JSON data from a specified URL and saving it to a variable that can be utilized in your content.

Developer assistance needed

You will need assistance from your development team to use Connected content. Please share this guide with them for proper implementation.

Example usage

Consider a scenario where you have a coupon service that returns a JSON response with a coupon code. The service returns the following JSON:

{
    "code": "coupon code"
}

You can fetch the coupon code and use it in your template as follows:

{% raw %}
{% connected_content https://example.com/couponwebservice.json :save result %}

Your coupon code is {% result.code %}
{% endraw %}

Usage

Liquid templates are available for both messages sent from Control Panel and API requests.

Control panel

In Pushwoosh, Liquid templates are applicable to all content fields of any channel message:

• Push notifications
• Emails

To add a Liquid Template to your message, insert it into the message’s body. You can do it when working with push or email elements, directly from the Customer Journey Builder interface.

Go to Customer Journey Builder > Create Campaign > Drag and drop the following elements to your canvas: Audience-based Entry, Push (or Email), and Exit. Connect the elements. Then click the Push icon, choose Custom content and insert your copy.

To add the Liquid logic, use tag values with the following syntax:

{% if TagName == ‘value’ %} Content to send in this scenario {% else %} Content to send otherwise {% endif %}

Then click Apply.

Template variables (Pushwoosh Tags) should not contain any spaces and have only alphanumeric values and underscores, e.g., my_tag or myTag instead of My Tag.
