It’s always frustrating when we accidentally undo something we’ve worked hard on - I’m sorry to hear about this happening!
At this time, there is no way to recover an event type once it’s been deleted from your account. You will need to recreate the event type from scratch, and we do apologize for that inconvenience!
There is some good news! Any bookings made on this event type before it was accidentally deleted will not be cancelled! You should still see all of these bookings under your “Scheduled Events” tab as well as on your add-to calendar, if you have set one up.
In the future, when working in your account, if you see the below pop-up, beware! Click “cancel” if you do not wish to permanently delete your event type.

The Product Team at Calendly is always taking feedback from our users to implement new, intuitive and exciting features in the future in order to streamline your scheduling process, and we have noted this in our internal feature requests. I know this isn't exactly what you wanted to hear but do hope the information helps, at least somewhat!
Has the product team enabled deleted events to be retreived?
Hi @AA313 - Unfortunately it is still not possible to retrieve a deleted event. These must be recreated from scratch - My apologies!
is there any way to recreate them and supply the new event with the same URL of the event you accidentally deleted? so Posted links to the deleted event would still work?
Hi @Penn66058 - Thanks for reaching out!
Yes, if you delete an event, you can always create a new one and adjust the link so its the same as the old event under Booking Page Options:

Let me know if you have any questions!
thanks, However… if what was deleted was a round robin event. is there a way to replicate that URL?
Just to confirm, was it a shared round robin event? Shared events do not have statically assigned URL’s so there would not be a way to replicate it for a new shared event.
Moving forward, if you setup your events through a Team Page, you can set static URL’s for your events there instead, this way you can reuse them if needed! You can read more on this here: https://help.calendly.com/hc/en-us/articles/16831517906711-How-to-set-up-a-team-page
