Hi ​@Luna2876 - Thanks for reaching out!

Right now, the only triggers for the Calendly/Zapier integration are:

• Invitee Created – Fires when someone books a meeting.
• Invitee Canceled – Fires when a meeting is canceled.
• Invitee No Show Created – Fires when a user is marked as a no-show.
• New Routing Form Submission – Fires when a routing form is submitted.

So there would not be a way to setup an automation for whenever a one-off meeting is created. I can pass this along to our product team as feedback!

Let me know if you have any questions

Thanks so much for your response. Is there any other way to automate the creation of a one-off meeting? even if not with Zapier?

Oh understood! If you’re looking to automatically create a one-off meeting, you can do this through Zapier as an action:
 

So depending on what you’re action is, the output can be a new one-off meeting. 

Let me know if you have any questions!

 thanks so much David!
