Embedded client error following samples and generating JWT

I made an meeting SDK app and a server to server app. In our site, we populate the webinars over API’s and now I want to load a webinar in a div on our website. But I get an error, and it’s misleading because we aren’t using the JWT App type?

Note: We do not want oauth login users have already logged into our site we should just be able to load the client and pass in all the information and they attend a webinar on our site. The site is just a regular PHP / HTML site so we use raw javascript and not much else.

Resources loaded on the page rendering the component view for zoom client:

//zoom component

Error: Using a Zoom JWT App type API Key (apiKey) is no longer available in version 2.7.0+ of the SDK. Please use an SDK App type SDK Key (sdkKey) instead and the SDK JWT Auth flow.

		console.log('join meeting success');

This leads me to believe the signature method is deprecated and I need to generate a valid JWT instead, ok I have updated our PHP code to generate a JWT instead but the docs/apps/etc. are all old now and it isn’t clear how to support this when using the join interface. So I tried just swapping the signature value with a generated JWT instead but still have issues initializing the page.

Any help would be appreciated to update and plug in the JWT to get this sample working. I generated the JWT, checked it in JWT.io, verified signature in JWT.io, and it has this content:

“alg”: “HS256”,
“typ”: “JWT”

“sdkKey”: “”,
“mn”: ,
“role”: 0,
“iat”: 1664537,
“exp”: 1671737,
“appKey”: “”, ← not sure why this is duplicated?
“tokenExp”: 1671737

have you updated the parameter in ZoomMtg.join ?

for JWT Signature it was:

      signature: signature,
      apiKey: ... ,

for SDK JWT Signature now:

      signature: signature,
      sdkKey: ... ,

Yes, thanks! Also found the documentation area where it documents the values and settings.

Another question, the “meeting hasn’t started yet” component is very small and I found the settings to set the video size to larger when a meeting is started (under customization) but the only way I have found how to make this view bigger is with CSS however I don’t want to hard code a bunch of sizes using CSS and media queries so is there not a way to make the view fill the screen during the “meeting hasn’t started” if someone is waiting for the host to start things?
