Is there an API to check if the Host id is scheduled for a meeting or no (is it in use) based on the Date and time parameters that we pass for concurrent session booking? How can we identify available Host Ids while scheduling a meeting through API?

Hi Tutoroot,&nbsp;

You can use our&nbsp; **List Meeting&nbsp;** API ([https://zoom.github.io/api/#list-meetings](https://zoom.github.io/api/#list-meetings)) which retrieves the meeting info including host\_id that is associated with an user ID or if you already know the meeting ID you can use our&nbsp; **Retrieve a meeting** &nbsp;API ([https://zoom.github.io/api/#retrieve-a-meeting](https://zoom.github.io/api/#retrieve-a-meeting)) that has the host\_id as well.

&nbsp;

Let us know if that helps.

I bought two pro hosts plan for my account.  
How do I know what are my user Ids and Host IDs for each plan?  
How can I create a meeting for a particlar User ID or host ID?

Hey @kumar,

You can use the [List Users endpoint](https://marketplace.zoom.us/docs/api-reference/zoom-api/users/users) to find the userIds. Or you can use the email address instead of userId in the url path to [create a meeting](https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/meetingcreate).

Thanks,  
Tommy
