Hi, I am trying to set up the in-browser JS client example by following the documentation I found here: [https://zoom.github.io/zoom-sdk-web/tutorial-getting-started.html](https://zoom.github.io/zoom-sdk-web/tutorial-getting-started.html) . I have thoroughly followed the procedure described there:  - Installed the Zoom Client  - Downloaded the code  - Ran npm install  - Updated the files with my evaluation API key/secret  - Ran http-server  - Created a meeting from the Zoom Client  - Opened the browser on 127.0.0.1:8081 (that’s what http-server told me)  - Copypasted the meeting number, added a name, and pressed join. Nothing happened.  By looking in the console, the library returned me this string {status: false, errorCode: 200, errorMessage: “No permission”, result: null, method: “join”} What did I do wrong? Update: I tried to set MY userName and MY passWord in the join method, and now I think I managed to connect to an existing session… even if I don’t see anything! The video is not visible, and the system prompts me to perform a phone call to get the audio… Is this the intended behavior? This web client seems pretty useless, this way… ---

Can you confirm that you are still receiving this message?   I just tested and cannot reproduce. ---

Hi, I actually get the same issue as the OP. I get this “No permission”. I am simply using the sample code from the Github and I obviously replace the API\_KEY and API\_SECRET with the one from my account. Is there any more steps to do ? ---
