Sendbird Find or Create a User

arazzo: 1.0.1
info:
  title: Sendbird Find or Create a User
  summary: Look up a user by ID and create them only if they do not already exist.
  description: >-
    An idempotent user-provisioning flow. It searches the application for a user
    by ID and branches: when the user already exists it ends with the existing
    record, and when no user is found it creates a new one with the supplied
    nickname and profile image. This makes user provisioning safe to retry.
    Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
