This article explains Zoom's rate limits when integrated with Calendly, allowing up to 100 meetings per user per day across all apps.
If you’ve integrated your Calendly account with Zoom, and you are receiving a large influx of bookings at one time, you may encounter Zoom’s rate limit.
Note that Zoom allows up to 100 meetings created per user within a 24-hour period. Zoom applies rate limits on the account level, across all apps created and installed on a Zoom account.
If you receive Action Required messages, and your meetings are scheduled without Zoom meeting details, please reach out to support from the Contact Us tab on our Help Center. Our team can check if your account is hitting a Zoom rate limit, and provide best next steps.
