The Conversation object (conv) provides access to conversation data and tools for managing the agent’s behaviour. It handles state management, flow transitions, SMS interactions, environment details, and voice selection.

print(conv.id)

if conv.project_id == "proj_123":
    print("Running in the main deployment")

  • "pre-release"
  • "live"
Example:
if conv.env == "live":
