User name is required. (300)

Hi,
I’ve been trying to access Zoom via the web client. It asks me for a username and then I get this error: “User name is required. (300)”.

I’ve also tried to input the username into the URL, according to this thread:

Force username when entering meeting using browser Zoom app

Hi!   We were wondering if there is a way to enter a Meeting using the browser version instead of Zoom app, for example in Chrome, and force the name of the participant.   The link to enter the meeting is something like this: and when we fill the name and actually enter to the meeting: https://zoom.us/wc/{IDMEETING}/join?pwd=&dn={PARTICIPANT_NAME}&track_id=&jmf_code=&meeting_result=   We tried using the “dn” parameter but it also asks the user for the user name before entering the meet…

But haven’t managed to get into a meeting. I’m wondering what I’m doing wrong

Anybody had an error like that before?

Thanks in advance and wish you all the best!

Hi @kadriko06,

If you are using the Web Client you can do so using the below example. Make sure to base64 the username for the un parameter

https://zoom.us/wc/{meeting-id}/join?prefer=1&un={base64-username}

Thanks

Hi,
Thanks for the reply but as I said above, it still asks for name when I try to connect.

For example when I go there: https://zoom.us/wc/9610451213/join?prefer=1&un=VGFybW8=
It should have my name set as ‘Marko’ I believe but still asks for my name. Am I doing something wrong?

Also, if there’s a password, will I just use URL like this? https://zoom.us/wc/9610451213?pwd=QmFpSGtOL0t4cmtEU3J1Y3JMOFdqZz09/join?prefer=1&un=VGFybW8=

Thanks in advance, really appreciate the help.

All the best!

Hey @kadriko06,

Gotcha, we have recently changed how the Web Client urls work for added security. You will have to enter your name and the captcha.

Thanks,
Tommy
