Programmatically closing Web Messaging session via backend API

Trying to force-close an active Web Messaging session from our Python backend to reset the guest context. The standard way to update a participant via /api/v2/conversations/{conversationId}/participants/{participantId} works for general messaging, but it doesn’t seem to terminate the WebSocket connection for web chat guests. Is there a specific API call or payload flag that triggers an immediate disconnect? Currently getting a 200 OK but the session remains active on the frontend. Need this for our tracing pipeline.

You’re looking at the wrong endpoint. Use the API to terminate the conversation session, not just update a participant.

import purecloudplatformclientv2 as pcc

api_instance = pcc.ConversationsApi(pcc.ApiClient())
try:
 api_instance.delete_conversations_messaging_conversation(conversation_id)
 print("Session terminated.")
except pcc.rest.ApiException as e:
 print(f"Failed: {e.status} {e.reason}")

The DELETE endpoint only marks the conversation as closed in the database. It doesn’t kill the WebSocket connection on the client side. You need to send a specific close event via the participant endpoint or handle it in your frontend logic.
