We have a Workplace Pro account and Server-to-Server OAuth app with the meeting:read:chat\_message:admin / webinar:read:chat\_message:admin scopes added. The corresponding events are subscribed in the Marketplace UI, but none of the chat events are being delivered from Zoom. Participant join/leave events on the same subscription work correctly.

Please enable the following webhook events on our account:

meeting.chat\_message\_sent  
meeting.chat\_message\_received  
meeting.chat\_message\_file\_sent  
webinar.chat\_message\_sent  
webinar.chat\_message\_received

Older posts here hint that DLP / Archiving for in-meeting chat might need to be enabled if that is the gating feature for meeting.chat\_message\_received and webinar.chat\_message\_received. If that is the case, please also enable that for our account since the option does no longer seem to be exposed to the settings UI.

Please note that

- our app is already deployed and working with the correct scopes active
- the webhook URL is verified
- I am receiving all other webhooks such as the meeting.participant\_left and meeting.participant\_joined successfully with the current implementation

The app report says that the meeting.chat\_message\_received and webinar.chat\_message\_received webhook events are never sent from Zoom, despite the scopes being correct in the app / the events added to the webhook.

Thank you kindly in advance,

Robin

@Authentic this is a DLP feature, you will need support to enable this.
