Handlebar Helper Function: If

Conditionally renders a block based on whether a value evaluates to true. This built-in helper is provided by the Handlebars.Net library.

This helper is available in the Winter ’26 release of Marketing Cloud Next (API version 65.0).

1{{#if condition}}
2  <!-- Content when condition evaluates to true -->
3{{else if condition2}}
4  <!-- Content when condition2 evaluates to true -->
5{{else}}
6  <!-- Content when condition and condition2 evaluate to false -->
7{{/if}}

The function renders the block template if the condition evaluates to true. If an {{else}} block is provided, it renders that block when the condition evaluates to false. The helper also supports {{else if}} blocks for multiple conditions.
