What do I do with my Web SDK key ?

Hello,

I’ve searched everywhere but I still don’t understand what should I do with my Web SDK credentials.

I’ve created my app, I have the infos.
I can already set up webinars, put the link on my front end and subscribers can join the meeting via Zoom.
But, of course, when I use the shortcode to create an embed webinar , it doesn’t work. I always have the message
“Joining meeting timeout.
Fail to join the meeting.”

Probably because my wordpress account is not link with my SDK app (If I understand what I’ve read). But I still don’t know how I can implement that with my wordpress website…

Someone available and nice enough to help ??

Thank you so much !
