Multiple emails being sent upon registration (via API)

Hi support

We are using the API to register a user onto a Zoom meeting. We are only using one call and this is the API function:

The function is working and the user is successfully registered onto the meeting but they are receiving multiple confirmation emails usually 2 but sometimes 3 (all with same time stamp).

We have looked into logs and settings but cannot see anything from our side on why multiple emails should be sent.

If you could help, that would be most appreciated.

Many thanks


Hey @zoomhelp,

Thank you for reaching out to the Zoom Developer Forum. Please send an email to with a copy of the emails, including the headers, and we’ll investigate this further from there.
