I have build two apps in zoom, server to server oAuth app and General app.  
I am using server to server oAuth app for scheduling meeting and using general app for creating signature to initialise and join meeting.|  
The host is able to join the meeting, but when the participant is trying to join, i am getting the belkow error-

{type: ‘JOIN\_MEETING\_FAILED’, reason: ‘This webinar requires registration.’, errorCode: 3099}

Hey @vishal2611  
It looks like you are enabling registration to your webinar. So make sure to send the registration link to participants so they can join or disable registration upon webinar creation

I haven’t added any scope of webinar when build app in zoom.
