This n8n workflow streamlines the process of booking meetings through a webhook, adding data validation, and providing feedback. It is designed to automate scheduling by receiving booking requests, validating the input data, creating the booking via an external API, and responding with success or error messages. The workflow ensures that incomplete data prompts an immediate error response, while complete data triggers an API call to set up a meeting.

The flow begins with a Webhook node configured to listen for POST requests on a specified endpoint. Incoming data from the webhook is immediately evaluated by a Switch node that checks whether all required fields (attendee name, email, phone, company, start time, and notes) are present. If the data is incomplete, the workflow responds with a 400 error and a message indicating insufficient information.

If all required fields are provided, the process proceeds to create a booking request by sending a POST request to an external booking API (Cal.com). The request includes attendee details and booking information, utilizing API keys and headers for authentication and content type.

Once the booking is successfully created, a confirmation response is sent back to the user, indicating the scheduled time of the meeting.

This workflow is particularly useful for automating appointment scheduling systems where external triggers or form submissions require validation before booking sessions. It reduces manual intervention, minimizes errors, and provides immediate user feedback, making it ideal for customer support, sales demos, or internal team scheduling.
