Single sign on callback

Hi, would it be possible to pass a token to the single sign on form to bypass it (like in the ios sdk).
If not, what would be the way to setup that login callback on the frontend?
I followed these:

Not sure what I should do on the callback windows.

Which Web Client SDK version?

To Reproduce(If applicable)
Steps to reproduce the behavior:

  1. Setup account to only logged users can join.
  2. Follow auth0 instructions to setup zoom sso.

Hey @ibennz,

Thank you for reaching out to the Zoom Developer Forum. Just to clarify, are you referring to skipping the form when you attempt to Join an Authenticated meeting with the Web SDK? Or, are you referring to using the Zoom client?

When it comes to the Web SDK, we don’t have a method to bypass the log in that I’m aware of. Can you provide more information on the callback that you are looking to create?


Hey @MaxM,

Thanks for the reply, yes it was to pass the token to the meeting to ease the single sign on flow. The other part of my question refers to how would I implement sso callback ?
I followed instructions from my post above. When I test with the web SDK, the callback sent to my server throw this: UnauthorizedError: No authorization token was found

The localhost test setup I am using:

Adding more context around that callback:

  • It happen when I require users to be authenticated and sign in through the single sign on form.
  • I did set the authentification profile of the account on zoom to my auth0’s tenant info.

What I did assume is that this is supposed to be sent back to my zoom’s location endpoint (as part of the SAML login flow), but I get this error {"status":false,"errorCode":6028,"errorMessage":"The signature is not trusted or invalid, please check the certificate in the Zoom SAML page.","result":null}

Below I attached few screenshots of the login flow and the console requests.

Hey @ibennz,

I really appreciate the additional information! I’ll need to reach out to some internal resources to make sure I’m providing accurate information.

Please send an email to with a link to this thread. If possible, please include a link to a git repo that has the zoom-sso-test code which demonstrates the issue.

I’ll investigate further from that ticket.


Hey @MaxM,
I did forward the email and also created this repo to reproduce the callback.

Hey @ibennz ,

Thanks for sharing your github repo and the Auth0 resources.

We’d like to know if the issue you are experiencing with custom Zoom SSO is with the Web Client SDK, or just in general, getting the SSO setup?


Hey @tommy,
I am experiencing issues with the implementation of Zoom SSO, regardless of the platform. I did follow auth0’s instructions. Afterwards Configuring authentication profiles using external authentication (admins) from here whenever the SSO login is initiated, I get the previously mentioned issue.

More context: The web portal SSO works perfectly.

Hey @ibennz,

I followed up with you in our ticket, please see my response if you want to setup a meeting to look at this issue.
