ZoomWebSDK - Fail to join the meeting - errorCode 200 - url: https://zoom.us/webSDK/recaptcha

I’m doing an integration where on registration some people will select whether or not they want to enter a specific zoom room.

I did the SDK setup and I’m testing it in the development environment (http://localhost)

I’m getting the error “Fail to join the meeting.”

Browser Console Error

{type: ‘JOIN_MEETING_FAILED’, reason: ‘Fail to join the meeting.’, errorCode: 200, url: ‘Web SDK Captcha - Zoom’}

Which Web Meeting SDK version?
2.1.0 loaded through CDN

Hey @vinicius.goncalves,

Thank you for reaching out to the Zoom Developer Forum. Are you able to share the meeting ID that you’re using when you see this? I would also try testing with the Sample Web App to remove any variables.


meetingId: [REDACTED]

Is my personal meeting ID

The sample web app is giving me Invalid Signature error.
