tip:

The assign tag can be combined with HTML to save you time and effort when creating multiple hyperlinks.

{% assign url = "https://www.examplelink.com" %}
<a href='{{url}}'>Click this Link!</a>

filter name	filter description
`property_accessor`	Takes a hash and hash key and returns the value in that hash at that key

Example hash : {“a” => 42, “b” => 0}

Example input: {{hash | property_accessor: 'a'}}

Example output: 42

Additionally, the property accessor filter allows you to template a custom attribute into a hash key to access a particular hash value.

note:

There is no way to instantiate a hash as a variable (i.e. expression) in Liquid within Braze.

`number_with_delimiter`	Formats a number with commas	`{{ 123456 \| number_with_delimiter }}`	123,456

This filter should always be used when personalizing a string in a JSON dictionary and is useful for webhooks in particular.
