How to use ZOOM SDK or API to Implement ZOOM meeting at the Pure PHP application.

I have created ZOOM API and SDK to integrate ZOOM meetings in my Application.
After spending some time in the implementation I found that I can not use "Iframe" to implement the ZOOM meeting.

I have got the Meeting list using ZOOM API,
but I can not get the flow that how could I manage showing a meeting at my application. 

I have checked the detail regarding SDK, I have added the CDN CSS and JS files in my page, 
but it's showing a black screen, 
I have added my KEY and SECRET in "index.js" file.

Now, what can I do to implement and get a ZOOM meeting using SDK or API. 
I have knowledge of PHP.
Please help on this if possible.
