Hi!

Calendly does not offer a “master” API key that grants access to multiple users’ calendars under one key. Each Calendly user has their own API key or OAuth token, which provides access only to their individual account and event types.

If you have admin or owner permissions within a Calendly organization, you can use your Personal Access Token (PAT) to retrieve data for other users in your organization. This allows centralized access to scheduling data, but please note that the Calendly API does not support creating scheduled events yet. Bookings must still be made through the Calendly scheduling links or interfaces.

For your use case—partnering with local restaurants to offer a Book A Table feature—you would likely need to direct customers to each restaurant’s individual Calendly booking page.

If you need further assistance, you can reach Calendly Support via live chat (available with paid plans) or email support@calendly.com.

I hope this helps!
