WebSDK-live transcription and closed captions

Implementing isSupportCC, using a personal account token, does not enable CC
(I can’t see it on my implementation)

The questions I have are:
Is this closed captions different from live transcription and am I expected to upload something
(the captions)
Is live transcription available in webSDK?
Are there any restrictions to this functionality or extra instructions not included in the documentation?
Is this expected behavior for only adding the isSupportCC: true?

Browser Console Error
No error messages shown even with debug on

Which Web Meeting SDK version?

Meeting SDK Code Snippets
The code snippets that are causing the error / issue so we can reproduce.

To Reproduce(If applicable)

}) then
use zoomMTG.join({


Device (please complete the following information):

  • Device: Macbook Pro
  • OS: MacOS
  • Browser: Chrome and firefox

Also it seems like I can’t embed media items into the post to help with screenshots

Hey @jose-muuvlabs,

Thank you for reaching out to the Zoom Developer Forum. Currently, the Web SDK does not support live transcription. When it comes to Closed Captioning, you would want to follow our guide on integrating with a closed caption service:
