Dynamic Content
Learn how to use placeholders, system variables, Handlebars, and components to create personalized and reusable content across Fyno templates.
When creating templates in Fyno, dynamic content plays a crucial role in personalizing your notifications. This guide explores the key features that enable dynamic content in templates, including Placeholders, System Variables, Handlebars, and Components. By leveraging these features, you can easily insert dynamic data and enhance the flexibility of your templates. Let’s dive into the details of each feature.
Placeholders
Below the "Channels" section on the left, you can find placeholders. Placeholders help you to add dynamic variables in your template. Placeholders are denoted by {{ }} . You may define the parameters of Placeholders by clicking on it, which opens up a pop-up window where you can define them. Once you add any placeholders in your templates using {{ }} and open the Placeholders popup, you will see an option 'New placeholders detected. Add them here?' . When you click YES, then the placeholder will get automatically added here.

Handlebars within Fyno support features like conditional operations, loops, date time formatting, partial searches, and custom helpers, making it a very helpful tool to use when creating your templates.
