Meeting.participant_joined webhook does not contain updated meeting topic (instant meeting)

I start an instant meeting. I then change the topic from “UserName’s Zoom Meeting” to a specific topic. Later when participants join their meeting topic is still “UserName’s Zoom Meeting”, not the updated meeting topic. Is there a way to get the updated meeting topic in the webhook, or have the webhook’s “topic” be accurate to the current meeting topic?


Which App Type (OAuth / Chatbot / JWT / Webhook)?

Which Endpoint/s?
meeting.partipant_joined (and several others that include the topic)

How To Reproduce (If applicable)
See above

Screenshots (If applicable)

Additional context
Is there a way to detect the meeting name change?

Hey @gavin,

Thanks for reaching out about this.

You raise a good point—currently, this is expected behavior, and the webhook will utilize the original meeting topic for instant meetings. However, I can definitely appreciate the case you’ve raised.

I’ve gone ahead and raised this as a feature request to see if it’s something we can implement (ZOOM-239461).

I’ll be happy to update this thread, should this be something we can do.


Well, thanks for replying. I’d love to see an update here if there is one.

The other thing I think you could consider is updating the client to set the title of instant meetings before they are created. The API allows that but as far as I can tell the client (MacOS at least) does not provide that capability.

Hi @gavin,

Thanks for the feedback. I’ve shared this with our team, and will be happy to keep you abreast of any updates along these lines.
