Hello zoom dev team,

I am trying to use the SDK authentication for React app using web SDK but I encounter issues.

I am now trying to use the sample application provided here :

> **[GitHub - zoom/meetingsdk-react-sample: Use the Zoom Meeting SDK in a React App](https://github.com/zoom/meetingsdk-react-sample)**
>
> Use the Zoom Meeting SDK in a React App. Contribute to zoom/meetingsdk-react-sample development by creating an account on GitHub.

> **[GitHub - zoom/meetingsdk-sample-signature-node.js: Generate a signature to...](https://github.com/zoom/meetingsdk-sample-signature-node.js)**
>
> Generate a signature to Start and Join Meetings and Webinars with the Zoom Meeting SDKs. - GitHub - zoom/meetingsdk-sample-signature-node.js: Generate a signature to Start and Join Meetings and Web...

In the signature sample app we can first see that the schema used is not the same as the documentation here :

> **[SDK Authentication](https://marketplace.zoom.us/docs/sdk/video/auth/)**
>
> The Zoom Developer Platform is an open platform that allows third-party developers to build applications and integrations upon Zoom’s video-first unified communications platform.

I think sample app seems to be correct ? So I tried to I configure the applications with my SDK key and secret and start the apps. Then when I try to join the meeting I got the following error :  
Joining meeting timeout.  
The meeting number is not found.

And in the console I can see this error code in the json error object :  
errorCode: 3707

I was able to decode the jwt token on my react application and got this :

```auto
{
   "sdkKey":" ******",
   "mn":"123456789",
   "role":1,
   "iat":1659926357,
   "exp":1659933557,
   "appKey":" ******", // same value as sdkKey
   "tokenExp":1659933557
}

```

It seems correct to me so I can not find the issue.

Do you have any idea of what I am doing wrong ?

Thank you.

Loic.

</div>

create a new simple test meeting

- Registration NOT required
- a simple Passcode
- no waiting room
- Options: Allow participants to join anytime

you can use it endless - if you don’t use it some (???) weeks, it will automaticly deleted from your zoom account

activate the debug-mode

```auto
ZoomMtg.init({
    debug: true,

```

remove the registration info “tk”

```auto
ZoomMtg.join({	
  tk: registrantToken // <- remove complete line

```

and test again

Hello @Jürgen

Thank you, I was able to solve my issue.

I think I made mistake with meeting ID, because even if I keep the line “tk: registrantToken”, it is still working.

So probably the documentation is not uptodate since when I use “app\_key” (documentation) instead of “sdkKey” (sample app) in the signature generation, I got error.

If someone from zoom check this message, it can be nice to verify that and maybe update the docs.

Thank you,

Loic.
