Python Appointment Booking Server

I’m building Appointment system, an AI receptionist for small businesses. I need a small backend server that connects Vapi to Google Calendar.
Requirements:
• ⁠Two endpoints: check open slots and create a booking
• ⁠Uses a Google service account JSON key to read and write a Google Calendar
• ⁠Looks up which shop a call belongs to by the

dialed phone number
• ⁠Deployed to Render or Railway so it’s live
• ⁠Simple REST API that Vapi can call as a custom tool

Deliverables:
• ⁠Working server with both endpoints
• ⁠Deployed URL
• ⁠Short README with setup instructions

Timeline: about one week.
If you’re interested, reply with your experience building Node or Python APIs and Google Calendar integrations.
That’s it — post it, and when someone replies, send them the JSON key, the calendar name, the Vapi assistant, and the Twilio number.
