Hi.

1. Can I reserve a meeting room in the web SDK?

2. How is a meeting ID created if I make multiple reservations with one ID?  
I would like to send you a link by email 3 days before the meeting.

- [zoom.us/j/{meetingId}?pwd=\*\*\*](http://zoom.us/j/%7BmeetingId%7D?pwd=***)  
I’m curious about the MeetingId generation rules.

Hey @eunjinKwak,

Thank you for reaching out to the Zoom Developer Forum.

If you want to schedule a meeting you can use the [Create a Meeting API](https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/meetingcreate)

When creating a recurring meeting, you can refer to the meeting with an occurrence ID before it happens and with a UUID after it occurs. You can use the join\_url from the API response to send to your participants.

Thanks,  
Max
