Intempt uses an open source templating language called Liquid to reference and create personalized content. The Liquid template language provides logical operators to control how you want to include user, product and recommendation content in your templates. You can use Liquid template language to personalize the content of the templates. For emails, you can also personalize the subject line and preheader of the email. 

About Liquid

Liquid templating language supports the use of objects, tags, and filters.

• Objects allow you to insert personalized attributes into your messages.
• Tags allow you to execute programming logic in your messages. For example, you can use tags to include intelligent logic, such as “if” statements, in your campaigns.
• Filters allow you to reformat personalized attributes and dynamic content. For example, you could convert a timestamp, such as 2022-09-07 08:43:50 UTC, into a date, such as September 7, 2022.

Terms to know

These terms are based on Shopify’s documentation.

Liquid personalization variables

While you can access a lot of information with Liquid, there are generally three types of variables you’ll mainly use to personalize messages for your audience: user attributes, account attributes, and products.

User attributes 

The user attribute scope represents attributes associated with customers. You can reference customer variables in any message or action except when working with anonymous users. User attributes can only be created for attributes that have user identifiers associated with them.

Input:

Output

John

Account attributes 

Account attributes use the account scope - that means the information is associated with account or company data. Account attributes can only be created for attributes that have account identifiers assigned.

Input

Output

Intempt technologies

Products will use any product data collected/ingested via Intempt. This can include product catalog data and any collected data item. With collection properties, you can reference catalog variables such as product name, image, URL, and other objects (product. Product data can be accessed only for collections that have product identifiers assigned.

Input

Output

Nike shoes

Liquid Fallbacks

Messages will fail if you attempt to use data that does not exist—like when person doesn’t have an attribute or an event doesn’t have a property you reference. To prevent this kind of error, you should implement an if statement to fallback to a static value when a variable (attribute, event property, etc) doesn’t exist.

You can write your own fallback statements using liquid

For example, a subset of people have a value for an attribute named plan_name, you could create a fall back like this:

That will show, "You are currently on our XYZ plan." for customers who have a value for their plan_name attribute and "Please choose a plan." for customers who do not have a value for their plan_name attribute.

Alternatively, if you would rather not show anything for People who do not have a value for their plan_name attribute you can just leave off the else statement like this:

Copy

That will show, "You are currently on our XYZ plan." for customers who have a value for their plan_name attribute and nothing at all for People who do not have a value for their plan_name attribute.

Filters and tags

Filters and tags make up the foundations of Liquid, and there are a number of them that you can use. In the first-name example, if you wanted to make sure it was capitalized, add a capitalize filter to the tag:

{{ customer.first_name | capitalize }}

If the field was full_name and you wanted to include only the first word/name, you could use:

{{ customer.full_name | split: " " | first }}

Check out the other filters and tags (and how to write them) in the complete Liquid documentation by Shopify.

More examples: what else can you do?

Note: If you are using our drag-and-drop email editor to add user data, if you have code which involves logical or comparison operators (&, >, or <), use our “Add Liquid” option in the text dropdown, rather than typing manually:

Countdown to an event

If your customers subscribe to an event—a webinar, they buy tickets to a movie or concert, etc—you can include a countdown to an event or specific date and time that your audience is interested in!

Copy

{% countdown point:64 font:roboto weight:light fg:000000 bg:f2f6f9 time:"2022-07-04 12:00:00 (GMT)" locale:en looping:true resolution:S frames:2 %}

Countdown timers take several parameters. Your timer must include the font size, the foreground (font) color, the background color, and the time you want to count down to.

Math operations with attributes

Attributes are stored as strings—even if the attribute value is a number or an integer. When you want to use a number/integer attribute in a math operation, or evaluate it against another number, you need to convert the attribute to a number/integer to ensure that your liquid statements evaluate properly. You can do this using plus to add zero to the attribute.

Copy

{% assign my_attribute = customer.my_attribute | plus: 0 %}

{% if my_attribute > 0 %}

  Your attribute is greater than 0!

{% else %}

  Oh no, your attribute is 0 or negative.

{% endif %}

Links

You can include attributes within links as well, in order to send your users to a custom page.

Example:

Copy

Displaying a timestamp as a regular date

Let’s say you have a customer attribute called expiration (for a trial, maybe) that you store as a timestamp. If you wanted to display that expiration date in messages as a human-readable date, you can do so with liquid. There are a few different date filters you can use with this, but here we’re just going to show you month name, day, and year.

Example

If you had a customer attribute called expiration with a timestamp value of 1596153600, you can do the following:

The result in your message would be July 31, 2022.

The spaces, commas, etc between the date filters are included in the output. So if you want 31/07/2022 you’d do %d/%m/%Y.

For the current date, you can use:

{{ 'now' | date: "%B %-d, %Y" }}

Displaying how many days left in a trial

Explanation

1. You can get the current epoch time with 'now' | date: "%s". %s is a formatting option.
2. The customer.trial_end date is in epoch time.
3. Since epoch time is in seconds, we’re dividing by 86400 (number of seconds in a day) to get the number of days. Keep in mind that this is integer division so it’ll be rounded down.

Localizing date

If you want to display the current date formatted like: 06:54 AM Février 21, 2017 you can use this code replacing the months with the proper names for your desired lanuage:

Show a different message based on day of week

Using data containing whitespace

We recommend adding data to Customer.io without spaces. But if you do (for example, if you send us an attribute called current city), here’s how you’d refer to it:

{{ customer["current city"] }}

Filtering out default data or specific data

Copy

{% if customer.first_name contains 'Visitor' %}

{% else %}{{ customer.first_name | capitalize }}

{% endif %}

Logical Operators

Logical operators determine the basic rules for evaluating true or false statements. You can also use `and` and `or` operators to combine logic statements to evaluate multiple conditions.

andEvaluate a statement as true when both conditions are true.
Syntax{% if condition1 and condition2 %}

  // do something if both condition1 and condition 2 are true

{% endif %}

Example

    {% if attribute.user.name == "bugs bunny" and event.episode_start == true %}

      What's up doc?

    {% else %}

      That's all folks!

    {% endif %}

Does not equal (!=)Use != to check that two values are not equal to each other.
Example{% if attribute.user.name != "daffy duck" %}

  Duck season!

{% else %}

  Wabbit season!

{%endif%}

equals (==)Use == to check if two values are equal to each other.
Example{% if attribute.user.name == "daffy duck" %}

  Wabbit season!

{% else %}

  Duck season!

{%endif%}

Greater than and Greater than or equal to (>, >=)Use > to match when one value is greater than another. Use >= to match when one value is greater than or equal to another.
Syntax{% if val1 > val2 %}

  // do something if val1 is greater than val2

{% endif %}

Example

    {% if attribute.user.acct_age_years > 1 %}

      Thanks for being with us these past years

    {% else %}

      Thanks for spending the last year with us!

    {% endif %}

Less than and less than or equal to (<, <=)Use < to match when one value is less than another. Use <= to match when one value is less than or equal to another.
Syntax{% if val1 < val2 %}

  // do something if val1 is less than val2

{% endif %}

Example

    {% if attribute.user.purchases < 5 %}

      Thanks for your support

    {% else %}

      Thanks for spending the last year with us!

    {% endif %}

orEvaluate a statement as true when either of two conditions are true.
Syntax{% if condition1 or condition2 %}

  // do something if either condition1 and condition 2 are true

{% endif %}

Example

    {% if attribute.user.name == "bugs bunny" or attribute.user.group == "looney toons" %}

      That's all folks!

    {% else %}

      See you later!

    {% endif %}

Loops and Conditionals

Loop through an array of items or set conditions determining the content that you want to show.

• caseCreates a set of conditions depending on a variable’s specific value—like a set of if, if-else, else conditions.
  For example, you might use this to display different text depending on if a attribute.user lives in a specific country.
  Syntax

{% case condition %} {% when "value1" %} text when condition is value1. {% when "value2" or "value3" %} text when condition is value2 or value3 {% else %} text when condition does not match other conditions {% endcase %}

for loopRepeatedly executes a block of code, most commonly to perform an operation for each item in an array. You might use a for loop in a message to provide a receipt of purchases (assuming an array of items in a purchase). Find more information about for loops and iteration here.Syntax{% for item in array %}

  {{ item }}

{% endfor %}

Example

    // You can output each item of the array

    {% for member in members_of_band %}

      {{member}}

    {% endfor %}

    // If the items are objects, you can output properties from each object

    {% for product in event.products %}

      - {{ product.title }} x {{ product.price }}

    {% endfor %}

ifExecutes a block of code if a condition is met. Use elsif to add multiple ‘if’ conditions and else for the block of code you want to execute if all conditions are false. Find more information about conditional liquid here.
Example{% if attribute.user.name == "chad" %}

  Hey Chad!

{% elsif attribute.user.name != "chad" %}

  Hey {{ attribute.user.name | capitalize }}!

{% else %}

  Hi Buddy!

{% endif %}

unlessLike an if conditional, but reversed: this tag executes a block of code if your condition is not met.
Example{% unless product.name == "cool beans" %}

  The beans are not cool.

{% endunless %}

Timestamps and Dates

Use these tags to get and manipulate dates and times.

add_dayAdds a day, or multiple days, to a given timestamp.
Syntax{{ <unix_timestamp> | add_day: <int_days> }}

Example

    {{ 1477430251 | add_day: 7 }}

add_monthAdds a month, or multiple months, to a given timestamp.
Syntax{{ <unix_timestamp> | add_month: <int_months> }}

Example

    {{ 1477430251 | add_month: 7 }}

add_yearAdds a year, or multiple years, to a given timestamp.
Syntax{{ <unix_timestamp> | add_year: <int_years> }}

Example

    {{ 1477430251 | add_year: 4 }}

dateFormat a date. Use the Ruby syntax reference for more information about date formatting syntax.
Input{{ 1483272000 | date: '%H:%M, %a, %b %d, %Y'}}

Output

    12:00, Sun, Jan 01, 2017

event_timestampThe UNIX timestamp when a particular event was performed. This time is different from now!
Syntax{{event_timestamp}}

nowThe current time in UTC. You must format time with date.
To modify date or time with add or subtract filters you must convert now into a unix timestamp first using date: '%s'. If you use our built in add_day, add_month, or add_year filters, you must convert the timestamp to an integer first. You can do this by using the plus filter to add 0 as shown in the second example below.
Example{{ 'now' | date: '%I:%M %p %B %d, %Y' }}

{{ 'now' | date: '%s' | plus: 0 | add_day: 1 | date: '%I:%M %p %B %d, %Y'}}

Output

    08:28 AM May 11, 2021

    08:28 AM May 12, 2021

subtract_daySubtracts a day, or multiple days, to a given timestamp.
Syntax{{ <unix_timestamp> | subtract_day: <int_days> }}

Example

    {{ 1477430251 | subtract_day: 7 }}

subtract_monthSubtracts a month, or multiple months, to a given timestamp.
Syntax{{ <unix_timestamp> | subtract_month: <int_months> }}

Example

    {{ 1477430251 | subtract_month: 2 }}

subtract_yearSubtracts a year, or multiple years, to a given timestamp.
Syntax{{ <unix_timestamp> | subtract_year: <int_years> }}

Example

    {{ 1477430251 | subtract_year: 4 }}

timezoneConverts a timestamp to a timezone you specify. You can use now instead of a timestamp. Timezone inputs can be -3 (specify your number) or UTC
Example{{ 1483272000 | timezone: '-8' | date: '%H:%M, %a, %b %d, %Y'}}

Output

    04:00, Sun, Jan 01, 2017

Array Filters

Liquid used to filter and manipulate arrays (lists of values). If your event or another incoming value is an array, you may iterate over the array with a `for` loop or grab items at a particular index of the array, to display information for your audience.

compactRemoves nil (empty) values from an array.
Input{{ "mick, keith, nil, Charlie" | compact }} 

Output

    mick, keith, Charlie

concatConcatenates arrays, joining them end to end. The resulting array contains all of the elements of both original arrays. concat does not remove duplicate entries unless you also use the uniq filter.
Input{% assign stones = "mick, keith, ronnie, charlie" | split: ", " %} 

{% assign beatles = "john, paul, george, ringo" | split: ", " %} 

{% assign rolling_beatles = stones | concat: beatles %} 

{{ rolling_beatles | join: ", " }}

Output

    mick, keith, ronnie, charlie, john, paul, george, ringo

cycleIn a ‘for’ loop, this tag loops through and outputs strings in the order they were passed.
Input

{% assign attribute.user.characters = ["coyote","bugs","tweety"] %} {% for character in attribute.user.characters %} 

• {{ character }}
 

{% endfor %}

Output

    

 

      

• coyote

      

• bugs
 

      

• tweety
 

    

firstReturns the first element of the array.
Inputacme.characters = ["Wile E Coyote", "Road Runner"]

{{ acme.characters | first }}

Output

    Wile E Coyote

joinJoins the elements of an array with the character passed as the parameter.
Inputacme.characters = ["Wile E Coyote", "Road Runner"] 

{{ acme.characters | join: ', ' }}

Output

    Wile E Coyote, Road Runner

lastReturns the last element of the array.
Inputacme.characters = ["Wile E Coyote", "Road Runner"]

{{ acme.characters | last }}

Output

    Road Runner

limitReturn a set number of values from an array or string.

    - 2 

    - 1

sizeReturns the number of characters (the size) of a string (in characters) or the number of elements in an array.
Input{{ "That's all, folks!" | size }}

Output

sortSorts the elements of an array by an attribute of an element in that array. Usually used with a ‘for’ loop. The order of the sorted array is case-sensitive!
Input{% assign beatles = "paul, john, ringo, george" | split: ", " %}

{{ beatles | sort | join: ", " }}

Output

    george, john, paul, ringo

sort_naturalSort the items in an array in case-insensitive order.
Input{{ "mick, keith, Charlie, Ronnie" | sort_natural }}

Output

    Charlie, keith, mick, Ronnie

{{ my_array | uniq | join: ", " }} 

Output

    lions, tigers, bears

whereCreates an array including only the objects with a given property value, or any “truthy” value by default. When using where, you provide two items separated by a comma: the key you want to match on and the value you want to match.
InputAll Players:

{% for player in collection.players %} 

  - {{ player.last_name }} 

{% endfor %}

      - Gretzky 

      - Jordan 

Number and Currency Filters

These are tags and filters that manipulate incoming number, integer, and timestamp values.

Some tags, like the `currency` and `format_number`, take an optional localization parameter, formatting the output for a specific locale. These tags use the format `{{ 10 | currency: "en-us" }}`, which would output `$10.00`.

We support the following localization values:

    af, ar, az, be, bg, bn, bs, ca, cs, cy, da, de, de-AT, de-CH, de-DE, el, el-CY, en, en-AU, en-CA, en-GB, en-IE, en-IN, en-NZ, en-US, en-ZA, en-CY, en-TT, 

    eo, es, es-419, es-AR, es-CL, es-CO, es-CR, es-EC, es-ES, es-MX, es-NI, es-PA, es-PE, es-US, es-VE, et, eu, fa, fi, fr, fr-CA, fr-CH, fr-FR, gl, he, 

    hi, hi-IN, hr, hu, id, is, it, it-CH, ja, ka, km, kn, ko, lb, lo, lt, lv, mk, ml, mn, mr-IN, ms, nb, ne, nl, nn, oc, or, pa, pl, pt, pt-BR, rm, ro, ru,
