Hey @jimig,

This is a known issue and we are working to fix it:

> [@Invalid characters in user\_name when receiving event notifications](https://devforum.zoom.us/t/invalid-characters-in-user-name-when-receiving-event-notifications/6123):
>
> Sometimes we see a large number of invalid characters in the user\_name field in the event notifications we receive from Zoom. This happens occasionally and is not easily reproducible. See a sample event notification below ( host\_id and account\_id intentionally Xed out): zoom event request: {“event”:“meeting.sharing\_started”,“payload”:{“object”:{“uuid”:“PQJnznlcTHWMByal4bv5PA==”,“participant”:{“id”:"",“user\_id”:“16778240”,“user\_name”:“Xiw\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u00…

(ZOOM-112804)

Thanks,  
Tommy
