  title: Sendbird Issue an Access Token and Greet the User
  summary: Create a user with an issued access token and send them a private channel greeting.
  description: >-
    Provisions a user with a session access token in one call, then creates a
    distinct one-to-one channel between a system account and the new user and
    posts a greeting. This is the typical pattern for authenticated client SDK
    onboarding where the backend mints the access token the client will use to
    connect. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
