Blueshift’s custom Liquid filters

Blueshift provides custom Liquid filters that you can use in the messaging templates.

aes

This is an AES 256 Encrypt/Decrypt filter. This filter returns a hex encoded AES 256 ciphertext of the input based on a given key, initialization vector and cipher name.

Example for encryption:

{{ 'testuser@getblueshift.com' | aes256_encrypt_v2: '9cc25c7879fc94d5a19eeb8e47573b8423becb608a9a4e9d3c25c20aa7e04357','7bdc922b354cc8fa8d3f2910ba7cc411' }}

Returns the following cipher text:

9be4086dd0f2592273dbe6e0000377ef94ab6aa3573f9344b4abbbbcf47088b7

Example: The Cipher text can also be decrypted as follows:

{{ '9be4086dd0f2592273dbe6e0000377ef94ab6aa3573f9344b4abbbbcf47088b7' | aes256_decrypt_v2: '9cc25c7879fc94d5a19eeb8e47573b8423becb608a9a4e9d3c25c20aa7e04357','7bdc922b354cc8fa8d3f2910ba7cc411' }}

Returns:

testuser@getblueshift.com

Example: The default cipher used is aes-256-cbc, but you can also use aes-256-ecb by passing the cipher name as the 3rd option. Note that the initialization vector is null for ecb mode.

{{ 'hamburger' | aes256_encrypt_v2: '9cc25c7879fc94d5a19eeb8e47573b8423becb608a9a4e9d3c25c20aa7e04357', null, 'aes-256-ecb' }}

Returns:

14d60bd236617adc84e23587f46addd1

any_contains

Check whether a reference string is present in a string or array.

Example:

{{ "ola" | any_contains:"a"}}

Returns: true

Example:

{% assign people = "fred, john, mary" | split: ", " %}
{{ people | any_contains: "m"}}

Returns: true

base_64

Base64 encoding is used to encode binary data for storage or transfer over media that can only deal with ASCII text. This ensures that the data that you send remains intact without modification during the transfer.

The base64_encode filter accepts string data and returns a character string that contains the base64-encoded version of the source string.

The base64_decode filter accepts a base64 encoded character string and returns the base64-decoded version of the encoded string.

base64_encode

Returns the Base64-encoded version of a string.

Example:

{{ "lorem ipsum" | base64_encode }}

Returns:

bG9yZW0gaXBzdW0=

For longer strings, line feeds are added to every 60 encoded characters.

Example:

{{ "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec molestie gravida" | base64_encode}}

Returns:

TG9yZW0gaXBzdW0gZG9sb3Igc2l0IGFtZXQsIGNvbnNlY3RldHVyIGFkaXBp c2NpbmcgZWxpdC4gRG9uZWMgbW9sZXN0aWUgZ3JhdmlkYQ==

base64_strict_encode

Similar to base64_encode except that no line feeds are added.

Example: 

{{ "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec molestie gravida" | base64_strict_encode}}

Returns:

TG9yZW0gaXBzdW0gZG9sb3Igc2l0IGFtZXQsIGNvbnNlY3RldHVyIGFkaXBpc2NpbmcgZWxpdC4KICAgIERvbmVjIG1vbGVzdGllIGdyYXZpZGE=

base64_decode

Returns the Base64-decoded version of an encoded string.

Example:

{{ "bG9yZW0gaXBzdW0=" | base64_decode }}

Returns:

lorem ipsum

For longer strings, new lines are ignored when the string is decoded.

Example:

{{ "TG9yZW0gaXBzdW0gZG9sb3Igc2l0IGFtZXQsIGNvbnNlY3RldHVyIGFkaXBp c2NpbmcgZWxpdC4gRG9uZWMgbW9sZXN0aWUgZ3JhdmlkYQ==" | base64_decode}}

Returns:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec molestie gravida

base64_strict_decode

Similar to base64_decode but any new lines in the string result in an error.

Example:

{{ "TG9yZW0gaXBzdW0gZG9sb3Igc2l0IGFtZXQsIGNvbnNlY3RldHVyIGFkaXBp c2NpbmcgZWxpdC4gRG9uZWMgbW9sZXN0aWUgZ3JhdmlkYQ==" | base64_strict_decode}}

Returns:

Liquid error (line 63): invalid base64

between

Checks whether a given number is between 2 numbers.

Example:

{{ 10 | between: 5, 15 }}

Returns: true

Example:

{{ 10 | between: 10, 15 }}

Returns: false

Example:

{{ 10 | between: 5, 10 }}

Returns: false

Example:

{{ 10 | between: 5.9, 10.1 }}

Returns: true

camelcase

Removes underscores and returns the camelcase version of the input string.

Example:

{{ "Foo_bar lorem_ipsum" | camelcase }}

Returns:

FooBar LoremIpsum

catalog

Use the Catalog Liquid function to include item information in your templates without using a recommendation scheme. The Catalog function provides direct access for pulling data from user input, events, related catalogs, and more for specific item ids.

For more information and examples, see Include Catalog without recommendations in templates.

catalog_items Catalog function to access catalog items.
product_list Variable to access a catalog item and its attributes.
catalog_item_id

The item_id for the catalog item. 

This can be a single item, multiple items, or a dynamic variable that represents an array of items.

Accessing a single item:

{% catalog_items product_list 'item_id1' %}
<p><b>Title:</b> {{product_list[0].title}}</p>
<p><b>Price:</b> {{product_list[0].price}}</p>
<p><b>Description:</b> {{product_list[0].extended_attributes.description}}</p>

catalog_liquid_singleItem.png

Accessing multiple items:

In this example, we are accessing three items. They are assigned to the product_list variable in the form of an array. The first item ‘item_id1’, is referenced as product_list[0], the second item ‘item_id2’ as product_list[1], and so on.

{% catalog_items product_list 'item_id1' ‘item_id2’ ‘item_id3’ %}
<p><b>Title1:</b> {{product_list[0].title}}</p>
<p><b>Price1:</b> {{product_list[0].price}}</p>
<p><b>Description1:</b> {{product_list[0].extended_attributes.description}}</p>
<p><b>Title2:</b> {{product_list[1].title}}</p>
<p><b>Price2:</b> {{product_list[1].price}}</p>
<p><b>Description2:</b> {{product_list[1].extended_attributes.description}}</p>
<p><b>Title3:</b> {{product_list[2].title}}</p>
<p><b>Price3:</b> {{product_list[2].price}}</p>
<p><b>Description3:</b> {{product_list[2].extended_attributes.description}}</p>

You can also use a for loop to access the catalog items:

{% for item in product_list %}
<p><b>Title: {{ item.title }}</b></p>
<p>Price: ${{ item.price }}</p> 
<p>Description: {{ item.extended_attributes.description }}</p>
{% endfor %}

escape_url

Escapes URL using the CGI specs.

It is similar to the Liquid replace filter, except that it accepts regex matches as well. If multiple matches are found, this filter replaces all occurrences with the replacement string.

The following examples show the replace and regex_replace filters. 

Example:

{{ "Take my protein pills and put my helmet on" | replace: "my", "your" }}

Example:

{{ "Take my protein pills and put my helmet on" | regex_replace: "\smy\s", "-your-" }}

Returns:

Take-your-protein pills and put-your-helmet on

shuffle

Shuffle items in an array.

Example:

{% assign shuffled_products = products | shuffle %}

sms_shorten_link (for Cloud App templates only)

Shortens long URLs, making them suitable for payloads with character limits, such as SMS or other services configured using Cloud App Studio.

  Note

  • This filter is only applicable to Cloud App templates.
  • When applying the sms_shorten_link Liquid filter in Cloud App templates, use single quotes to enclose strings.

Example:

{"url": "{{'https://www.example.com/a-very-long-url-for-shortening-and-optimization' | sms_shorten_link }}"}

Returns:

{"url": "https://bsft.io/z/tiYwlQDtQWhW"}

time_zone

Format ISO 8601 compliant dates into a given timezone. Here's a list of Time Zones this filter supports.

Here are some examples:

Example:

{% assign sign_up_date = "Thu Nov 29 2001 14:33:20 UTC" %}
{{ sign_up_date | time_zone: 'Hong Kong' }}

Returns:

2001-11-29 22:33:20 +0800

Example:

{% assign sign_up_date = "29/11/2001 00:00:00 -0900" %}
{{ sign_up_date | time_zone: 'Hong Kong' }}

Returns:

2001-11-29 17:00:00 +0800

The time_zone filter returns a date and hence the output can be chained with a date filter to format the date value.

Example:

{% assign sign_up_date = "Thu Nov 29 2001 14:33:20 UTC" %}
{{ sign_up_date | time_zone: 'Hong Kong' | date: '%d/%m/%Y %H:%M:%S %Z' }}

Returns:

29/11/2001 22:33:20 HKT

You can also offset time by the hour value passed. In this example, the original time value is offset by -7 hours.

Example:

{% assign sign_up_date = "2015-12-01 10:00" %}
{{ sign_up_date | time_zone: -7 | date: '%d-%m-%Y %H:%M' }}

Returns:

01-12-2015 03:00
