Backend API to force close Web Messaging session?

Quick question about closing Web Messaging sessions programmatically from our backend.

We are building a cleanup routine in Python to terminate stale guest sessions via the API.

  • Genesys Cloud Web Messaging SDK
  • Python 3.11
  • genesyscloud SDK v10.0.0

I cannot find an endpoint in /api/v2/conversations or the Guest API to explicitly close a web messaging conversation. The standard DELETE or POST with close intent seems to require client-side initiation or fails with 405 Method Not Allowed.

Is there a specific API call to force-close the session from the server side?
