  • tel: - Phone numbers
  • sms: - SMS/text message links
  • Variables - Dynamic links using bot variables

​
URL Normalization

  • Links without protocols are automatically prefixed with https://
  • External links open in new tabs for better user experience
  • Proper URL validation ensures link functionality

​
Content Organization

​
Multiple Text Elements

  • Rich text content is organized as an array of elements
  • Each element can contain different formatting and content types
  • Empty content is visually indicated with reduced opacity

​
Chaining Text Bubbles

Multiple consecutive text bubbles create smooth animations and natural conversation flow:
  • Each bubble appears with a typing animation
  • Users can process information in digestible chunks
  • Better engagement compared to single long messages

​
Variables and Dynamic Content

Text bubbles fully support variable insertion:
  • Insert variables anywhere in your text content
  • Variables are replaced with actual values at runtime
  • Use variables in links for dynamic navigation
  • Support for both text content and link URLs

​
Best Practices

​
Content Structure

  • Break long messages into multiple text bubbles
  • Use formatting to emphasize important information
  • Keep individual bubbles concise and focused
  • Use descriptive text for links rather than raw URLs
  • Test variable-based links to ensure they resolve correctly
  • Consider using different link types (tel:, mailto:) for better user experience

​
Variable Integration

  • Ensure variables have fallback values or are properly validated
  • Test variable replacement in different contexts
  • Use meaningful variable names that make content self-documenting

​
Troubleshooting

  • Verify the URL format includes proper protocol (http/https)
  • Check that variable-based links contain valid URLs when resolved
  • Ensure special link types (tel:, mailto:) are formatted correctly

​
Variables Not Displaying

  • Confirm variable names match exactly with defined variables
  • Check that variables have values before the text bubble is reached
  • Verify variable syntax and formatting in the rich text editor

​
Empty or Missing Content

  • Text bubbles with no content appear with reduced opacity
  • Ensure rich text content is properly saved and not accidentally cleared
  • Check that rich text elements are properly structured in the data model
