  title: Twilio Create a Conversation and Attach a Scoped Webhook
  summary: Create a Conversations thread, then attach a conversation-scoped webhook that targets your service.
  description: >-
    An event-driven Conversations setup pattern. The workflow creates a new
    conversation and then attaches a conversation-scoped webhook to it, pointing
    a webhook target at the supplied callback URL so that events on this specific
    conversation are delivered to your service. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
