Text variables allow you to create dynamic templates where text content can be personalized for each recipient. Instead of creating multiple versions of the same design, you can define variables once and update their values through the API to generate personalized images at scale.

Creating Variables

​
Define Variables

  1. Access the Variables panel in the left sidebar
  2. Click the + button to add a new variable
  3. Select Text as the variable type
  4. Enter:
  • Variable name (e.g., ‘customerName’)
  • Default value for canvas preview

​
Best Practices

  • Use descriptive variable names
  • Set meaningful default values that represent real data
  • Keep names simple and avoid special characters

​
Using Variables in Text Elements

​
Insert Variables

  1. Select any text element in your design
  2. Type {{ in the text input field
  3. Choose from the dropdown of available variables
  4. Variable will appear as {{variable_name}}

​
Editing Text with Variables

  • Mix static and dynamic content freely
  • Example: Hi {{first_name}}, your order #{{order_id}} is ready!
  • Variables update in real-time on the canvas

​
