  title: Twilio Sync Document Lifecycle
  summary: Create a Sync Service, add a Document to it, then update the Document's data.
  description: >-
    A Twilio Sync provisioning pattern. The workflow creates a new Sync Service
    to act as the container namespace, creates a Sync Document inside that
    Service with an initial JSON data payload and a unique name, then updates
    the Document with a new data payload. This is the standard chain for
    standing up real-time shared state that clients can subscribe to. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
