ISSUE
Webex hosts encounter an error message stating 'Request failed with status code 400' when attempting to launch a Slido Event (Poll/Q&A) within Cisco Webex Meetings. This error disrupts the interactive features of meetings, such as live polling and Q&A sessions, which are essential for engaging participants.




RESOLUTION
To address the 'Request failed with status code 400' error, follow these steps:

1. Submit a problem report to Webex detailing the issue encountered.
2. Open a support case with Slido and provide the problem report ID from Webex for reference.
3. Create a new Slido event directly on the Slido website (http://slido.com) as a workaround.
4. Once the new Slido event is created, select it within the Cisco Webex Meetings Slido Apps to continue your meeting activities.

CAUSE
The 'Request failed with status code 400' error typically indicates a bad request was sent to the server. This can occur for various reasons, such as incorrect request formatting, missing parameters, or configuration issues within the Slido integration in Webex Meetings. The error suggests that the request made by the host to initiate a Slido Event does not comply with the server's expectations or the current Slido integration's limitations.
