Encountering CORS Error When Setting Up Zendesk SSO with AWS Cognito via OpenID

Hello,

I am currently attempting to set up Single Sign-On (SSO) in Zendesk using OpenID connected to AWS Cognito. During the OAuth 2.0 authorization process, I am encountering a CORS (Cross-Origin Resource Sharing) error, which is preventing a secure connection from Zendesk to Cognito.

Here are the details of my current setup and the request:

https://{region_Id}.amazoncognito.com/oauth2

Callback URI: https://{zendesk_domain}/access/oidc/callback

  • Error Message: CORS policy error, indicating that our request was blocked by the browser because it does not comply with the Cross-Origin Resource Sharing policy.

I have confirmed that the callback and logout URLs are correctly set in the AWS Cognito's App client settings, and I have checked the allowed origins setting. I would like to understand if there might be other settings that could cause this issue, or if there are recommended steps to try?

Thank you very much for your help!

    Could you please grab a HAR file to help us investigate? Feel free to send it in an email to me directly if you'd prefer (caroline at zendesk dot com).

    We were able to do a little bit more digging and we actually found an issue on our side where we didn't respect the email_verified claim being sent a string. We've made some changes on our end and from what we can tell it should be working as expected for you now! Can you confirm?
