Am I on the right track experts?
I’m building AI Voice Agents for real estate, focused on cold calling and lead qualification. My plan is to: 1. Start with a case study, 2. Package it as a done-for-you lead qualification service + cold calling Agent service 3. Scale towards my first £1000 and 10k For those of you who’ve been in the game longer: Do you see real estate Voice Agents as a solid service to sell right now? If yes, what would you do differently to make it more appealing/valuable to agents or any other niche? If no, what direction would you suggest I pivot or adjust towards that has stronger demand? Or maybe I'm doing it the right way and I'm just wasting your time 😅 I’d really value your perspective so I can avoid rookie mistakes and double down on what works ASAP.

N8N Webhook not triggering via tool call in Vapi
Hey guys, why am I getting this error sometimes when calling my webhook in my self-hosted instance on hostinger and other times it works as intended? [ { “name”: “Booking_Tool”, “toolCallId”: “call_PjoAEFxxxxxxxxxxxxxxxxG3d6”, “type”: “function”, “serverUrl”: “https://n8n.xxxxxxx.hstgr.cloud/webhook/2d97f358-xxxx-xxxx-xxxx-7a22d957f420”, “error”: "Your server rejected tool-calls webhook. Error: " } ] Additional context: I'm using Vapi and it always works as intended when doing the built-in test call for the tool. I am also not seeing the webhook node failing within executions, which makes me think it’s not even getting to the node and failing at server level. Been trying to figure this out for a couple of days. Would appreciate any help.

Troubleshooting AI Receptionist Integration with Google Calendar
Hi guys, I'm using VAPI + MAKE for my AI receptionist, but when I run my scenarios, it doesn't seem to be talking with my google calendar. What could be the reason? I'm using cal.com to connect my calendar. I have inserted the right API keys in the modules in make. Please help if possible
