changing or canceling a booking within 24 hours

Hi ​@mottishachar - Thanks for reaching out.

At this time, there is not a way to limit the reschedule link for the invitee. However, you can remove the link from the invitation so the Invitee will need to contact you before changing the meeting details. This is how most of our users workaround this.

You can read the instructions on how to remove the cancel/reschedule links here: https://help.calendly.com/hc/en-us/articles/28926585452951-How-to-include-cancel-and-reschedule-links-for-invitees

Let me know if you have any questions!
