Zoom Events API: Is there a way to send confirmation emails when creating tickets via API?

[takahara_yuuki]

Hi Zoom Developer Community,

We are developing a medical seminar platform that integrates with Zoom. Previously, we used the **Zoom Webinar API** (`POST /v2/webinars/{webinarId}/registrants`) to register users programmatically. This worked great - users could register with one click, and Zoom automatically sent confirmation emails with join links.

Recently, we started using **Zoom Events (Webinar Plus)** for our seminars. We discovered that the standard Webinar API doesn't work with Zoom Events and returns error code 3000:

{"code": 3000, "message": "Registration has not been enabled for this webinar: xxxxx"}

We then tried the **Zoom Events Tickets API** (`POST /v2/zoom_events/events/{eventId}/tickets`), which successfully creates tickets. However, we found that **confirmation emails are not automatically sent** when using this API.

## Our Question

Is there any way to achieve the following with Zoom Events via API?

1. Register a user programmatically (one-click registration from our platform)
2. Have Zoom automatically send a confirmation email with the join link

We want to avoid implementing our own email system if possible, as this adds significant development and maintenance overhead.

## What we've tried

- Using the Tickets API with various parameters
- Searching for email-related settings in the API documentation
- Looking for webhook-triggered email options

## Our use case

- Medical professionals register for seminars on our platform
- We pre-fill their information (name, email, hospital, specialty) from their profile
- One-click registration improves user experience significantly

Any guidance on whether this is possible, or if there are planned features to support this, would be greatly appreciated.

Thank you!
