  title: Workday Extend Upsert Worker Custom Object Data
  summary: Confirm a custom object definition, check whether a worker already has data, then create or update it.
  description: >-
    Writes custom object data onto a worker, choosing the right messaging based on
    whether the data already exists. The workflow resolves the custom object
    definition, reads any existing instance for the worker, and then writes the
    data via the create-or-update endpoint, branching to label the outcome as a
    create or an update. Every step spells out its request inline so the flow can
    be read and executed without opening the underlying OpenAPI description.

  summary: Read a worker's custom object data and create or update it via the upsert endpoint.

    Resolves the custom object definition, checks whether the worker already has
    an instance, and writes the supplied data with the create-or-update endpoint,
    branching on whether the prior read found existing data.
  inputs:
    type: object
    required:
    - definitionId
    - workerId
    - customObjectName
    - data
    properties:
      definitionId:
        type: string
        description: The unique identifier of the custom object definition to validate against.
      workerId:
        type: string
        description: The unique Workday identifier of the worker.
      customObjectName:
        type: string
        description: The name of the custom object type.
      data:
        type: object

  steps:
  - stepId: resolveDefinition
    description: >-
      Retrieve the custom object definition to confirm the target custom object
      type exists before reading or writing instance data.

  - stepId: readExisting
    description: >-
      Retrieve the worker's current custom object data. A 200 indicates existing
      data; a 404 indicates none exists yet. Both outcomes are accepted so the
      flow can branch on the result.
