Subject: 🗓️ Calendar Sync Issues with AI Receptionist Agent — Need Help After 1 Week of Testing Hi Vapi team @Kings_big💫 👋, I’ve been trying to get the calendar integration working for my AI receptionist voice agent for the past week, but I'm still facing issues that are blocking progress. To enable appointment booking and availability checks, I’ve linked both Outlook and Google Calendar using the webhook setup. However, the agent gives inconsistent responses — sometimes it says a slot is booked, sometimes not, even when the same slot is clearly occupied. This happens across both calendar systems. I’ve verified the webhook payloads and re-tested the flows multiple times. Can you please help me resolve this? 🙏 Is there a recommended or stable setup for accurate availability detection and reliable booking? Appreciate your support! Thanks, haris
