Hi, thanks a lot for this forum.

I stumbled across an issue that got me here:

# [Joining meeting timeout - Signature is invalid](https://devforum.zoom.us/t/joining-meeting-timeout-signature-is-invalid/41209)

I installed the sample as well and had the same problem. Can you help me out?

Warmly JAV

Hey @jahrvos,

Thank you for reaching out to the Zoom Developer Forum. First, please make sure that you are using the API Key and API Secret from a [JWT App](https://marketplace.zoom.us/docs/guides/auth/jwt) instead of an SDK app.

Let me know if that helps.

Thanks,  
Max

Hi,  
thanks for the reply,  
I am using the JWT keys, found the right host\_id, which helped (no more invalid signature), but got an empty list.  
I seem still to do something wrong.

I downloaded the sample app from [GitHub - zoom/sample-app-web: Zoom Web SDK Sample App](https://github.com/zoom/sample-app-web)  
I replaced API KEY/SECRET with actual values  
Using $list = $objZoom-\>getRecordingList(‘123456’) gives:

host\_id=123456&api\_key=actualAPIkey&api\_secret=actualSECRET&data\_type=JSONhttps://api.zoom.us/v2/recording/listarray(4) { [“host\_id”]=\> string(6) “123456” [“api\_key”]=\> string(22) “actualAPIkey” [“api\_secret”]=\> string(36) “SECRET” [“data\_type”]=\> string(4) “JSON” } string(0) “”

Hey @jahrvos,

Can you clarify how to reproduce the issue? The code that you provided doesn’t look like it comes from our Web SDK Sample App.

Thanks,  
Max
