Create a Calendly availability API endpoint for real-time scheduling data

This n8n template implements a Calendly Availability Checker that provides real-time availability information for your Calendly event types via a simple API endpoint

Who's it for

This template is designed for developers, businesses, and service providers who need to programmatically check Calendly availability. It's perfect for:

- Web developers building custom booking interfaces that need real-time availability data - Chatbot developers who want to suggest available times to users - Website builders who want to display available slots on their site - Integration developers who need to check availability before creating bookings - Businesses that want to build custom scheduling experiences on top of Calendly - Service providers who need availability data for their own applications or dashboards

How it works / What it does

This workflow creates a RESTful API endpoint that returns real-time availability information from your Calendly account. The system:

1. Accepts webhook requests via POST with optional parameters: - eventtypeuri (optional) - Specific event type to check - daysahead (optional, default: 7) - Number of days to check ahead

2. Authenticates with Calendly API using OAuth2 credentials to access your account
