What’s the right way to set wrap-up codes programmatically after an interaction ends? I’m trying to hit PATCH /api/v2/conversations/voice/{conversationId}/participants/{participantId} with a payload containing the wrap-up code. I keep getting a 409 Conflict, presumably because the conversation is already closed. Here’s the payload: { "wrapUpCode": { "id": "abc-123" } }. Am I hitting the wrong endpoint or is there a specific flag I need to include?
