  title: Bentley Provision an iModel Inside a New iTwin
  summary: Create an iTwin project container, provision an iModel inside it, and wait for initialization.
  description: >-
    The canonical bootstrap flow for the iTwin Platform. It first creates an
    iTwin — the top-level project container — then creates an iModel inside it,
    and finally polls the iModel until its state reports initialized so that
    downstream changeset and named-version operations can safely begin. Each
    step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI descriptions.

  summary: Create an iTwin, create an iModel inside it, and poll until initialized.
  description: >-
    Provisions a fresh iTwin project container, creates an iModel within that
    iTwin, and then polls the iModel until it reports an initialized state.
  inputs:
    type: object
    required:
    - itwin
    - iModelName
    properties:
      itwin:
        type: object
        description: The iTwin creation payload (e.g. displayName, class, subClass).
      iModelName:
        type: string
        description: The human-readable name for the new iModel.
      iModelDescription:
        type: string
        description: An optional description for the new iModel.
  steps:
  - stepId: createItwin
    description: >-
      Create the top-level iTwin project container that will own the iModel and
      its reality data.
    operationId: CreateiTwin
    requestBody:
      contentType: application/json
      payload: $inputs.itwin
    successCriteria:
    - condition: $statusCode == 201
    outputs:
      iTwinId: $response.body#/iTwin/id
  - stepId: createImodel
    description: >-
      Create an iModel inside the newly created iTwin. The iTwinId links the
      iModel to its owning project container.
    operationId: CreateIModel
    requestBody:
      contentType: application/json
      payload:
        iTwinId: $steps.createItwin.outputs.iTwinId
        name: $inputs.iModelName
        description: $inputs.iModelDescription
    successCriteria:
    - condition: $statusCode == 201
    outputs:
      iModelId: $response.body#/id
      state: $response.body#/state
  - stepId: pollInitialized
    description: >-
      Poll the iModel until its state reports initialized. The iModels API
      provisions storage asynchronously, so the resource may start as
      notInitialized immediately after creation.
