Carousel Messages
Definition
A carousel is a rich media message format consisting of 2-10 scrollable cards presented horizontally in the chat interface. Each card typically contains an image, a title, a brief description, and one or more action buttons (e.g., 'View Details', 'Add to Cart', 'Learn More'). Carousels are particularly effective for presenting multiple options at once — product recommendations, article listings, plan comparisons — allowing users to browse and select without leaving the conversation. Support for carousel messages varies by channel: web chat and Facebook Messenger support them natively; WhatsApp requires workarounds.
Why It Matters
Carousels pack more information into less vertical space than sequential text responses, making them ideal for product discovery and option selection. They are proven to increase click-through rates compared to text-based lists because visual presentation with direct action buttons reduces the path from interest to conversion. For e-commerce, SaaS pricing pages, and content recommendation use cases, carousels are a high-value chatbot UI pattern.
How It Works
The bot response payload includes a carousel object with an array of card objects. Each card object specifies the image URL, title, subtitle, and an array of button objects with labels and action payloads (URL, postback text, etc.). The chatbot platform renders these as a horizontally scrollable component in the widget. Users swipe left/right to browse and tap buttons to take action. On channels without carousel support, the platform may fall back to rendering cards sequentially.
Real-World Example
A user asks the chatbot 'What are your most popular templates?' The bot responds with a scrollable carousel of 5 template cards — each with a preview screenshot, template name, and a 'Use This Template' button. The user swipes through the options, spots one they like, and taps the button to apply it immediately from within the conversation.
Common Mistakes
- ✕Creating carousels with too many items (more than 5-6) — users rarely scroll through long carousels.
- ✕Using carousel images without consistent aspect ratios — mismatched image dimensions create a visually inconsistent, unprofessional look.
- ✕Deploying carousels on channels that don't support them without testing the fallback experience.

Rich Media Messages
Rich media messages are chatbot responses that include visual or interactive elements beyond plain text — such as images, videos, documents, clickable cards, buttons, and links. They make conversations more engaging, convey information more effectively, and guide users toward actions with minimal friction.
Quick Replies
Quick replies are pre-defined response options presented as tappable buttons below a chatbot message, allowing users to respond with a single tap rather than typing. They guide conversations, reduce user effort, and increase response rates by presenting the most likely next steps as interactive choices.
Bot Response
A bot response is any message the chatbot sends to the user — an answer, a question, a confirmation, or an action notification. Crafting effective bot responses requires balancing accuracy, brevity, tone, and helpfulness. The response is the only output the user sees, making it the most direct expression of the chatbot's quality.
Conversation Design
Conversation design is the discipline of crafting chatbot interactions that feel natural, intuitive, and effective. It applies principles from UX design, linguistics, and psychology to design dialogue flows, bot responses, and error handling — ensuring users can easily achieve their goals through conversation.
Channel Integration
Channel integration is the process of deploying a chatbot across multiple communication platforms — website widgets, WhatsApp, Slack, SMS, Facebook Messenger, email, and more. A well-integrated chatbot delivers a consistent experience regardless of which channel the user chooses, meeting customers where they already are.
