Is there any api or Method to disable chat, poll, QA etc

Hi @sulekhalive,

To delete a poll for a scheduled meeting, you can use this endpoint:
https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/meetingpolldelete

To update whether polling is enabled for an entire account, you can use this endpoint:
https://marketplace.zoom.us/docs/api-reference/zoom-api/accounts/accountsettingsupdate

Meeting Chat cannot be controlled via API, you will need to use the UI/Client for this:

For Q&A during a Webinar, you will need to set this in the UI:

Alternatively, you might consider using a template for webinars, which can be applied via API. This is covered in this thread:

Let me know if this helps to clarify,
