3 Best Callback Widget Examples
Here are three real-life examples of callback widgets to help you understand how they work.
1. Exit-Intent Callback Prompt

Sath uses a smart exit-intent callback popup that triggers when a user is about to leave the page. Its simple and clear design, with a bold heading “Before you go!”, gets attention.
The popup offers a direct value: a 10-minute call to evaluate the visitor’s identity security.
Why it works:
- Targets users who are about to bounce
- Provides value (security evaluation)
- Time-based hook (10 minutes)
- Not pushy
2. Sticky Side Button with Slide-In Form

This widget is sticky on the left side of the screen as a “Contact” button. On click, it slides in a form to request a callback. Subtle but always available.
Why it works:
- Non-intrusive design
- Always visible while browsing
- Smooth animation
- Good for service or SaaS websites
3. WhatsApp Call Widget

Instead of a callback form, Artoon uses a floating WhatsApp icon in the bottom left.
Clicking it opens a WhatsApp chat to request a call or continue the conversation.
Why it works:
- Taps into a familiar platform
- Instant connection through mobile
- Good for agencies and service providers
- Reduces friction for visitors who prefer messaging
These examples show how callback widgets can look and work differently depending on your goals and audience.
Whether you want to reduce drop-offs, make it easy to get in touch, or add a WhatsApp touchpoint, there’s a style for every use case.
