How to extract realtime in meeting chat message?

API and Webhooks Meetings
1

Hello,

I’m developing a system to extract realtime in-meeting video,audio and chat.

I saw the document shows RTMS support chat message in meeting, but when I tried it, chat message are not received. Is there anyway to get realtime in-meeting chat message?

Thanks.

hi @Yuiki ,

Chat message support for RTMS was a development target, but Zoom has decided not to add it at this time.

If you want to process chat messages in real time, then the only alternative today is to write a Zoom browser-based bot and ‘hack’ into the chat content being output into the DOM.

There is no API or Appsdk call listed at this time.

All the best

You could look into the webhooks for meeting.chat_message_sent

Zoom’s own RTMS docs explicitly say chat isn’t available. The RTMS overview also describes RTMS as a pipeline for live audio, video, and transcript data, which matches that limitation.

Zoom staff have reiterated this on the forum too - for example, in an RTMS troubleshooting thread they stated they’re “still working to support … chat data”. If you need in-meeting chat today, use the Meetings webhook event meeting.chat_message_sent or capture chat from an in-meeting client via the Meeting SDK callback onChatMsgNotification.

You could also consider use a third-party meeting bot API like Recall.ai to capture chat messages (along with video, audio, and other meeting metadata) in real-time or after the meeting has ended. We’ve helped thousands of developers with their Zoom implementations and can help you with yours too
