Looking for the Best Prompt Examples for VAPI AI Voice Agent (Booking, Rescheduling & Cancellation in Cal.com using make)

I’m currently building an AI Voice Agent using VAPI + Make.com, and I’m trying to optimize the prompts for the best real-world performance.

Specifically, I’d love to see how you’re handling these use cases:✅ Booking new appointments in Cal.com✅ Rescheduling existing bookings✅ Cancelling appointments

If anyone has working prompt examples or a JSON file setup in Make.com that handles these scenarios smoothly, it would be hugely appreciated! 🙌

I want to understand how you’re structuring your prompts to make the agent more natural and accurate in understanding user intent.

If you’ve tested different approaches or found what not to do, please share your learnings too — it’ll help a lot of us building similar flows!

Thanks in advance
