  title: IBM Cloud IAM Deprovision a Service ID
  summary: Resolve a service ID by name, prove it is dormant, unlock it, and delete it with its keys.
  description: >-
    Retiring a machine identity without breaking whatever quietly still depends on
    it. The workflow resolves the service ID by name, inventories the service ID
    API keys in the account that deletion will destroy, and reads the identity's
    authentication activity to prove it is genuinely dormant before anything is
    removed — the check that separates a clean decommission from an outage. It then
    unlocks the identity, since production service IDs are routinely locked, and
    deletes it along with its keys. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.

workflows:
- workflowId: deprovision-service-id
  summary: Find a service ID by name, confirm it is unused, then unlock and delete it.
  description: >-
    Looks the service ID up by name, lists the account's service ID keys, reads its
    activity to establish last authentication, unlocks it, and deletes it together
    with all associated API keys.
  inputs:
    type: object
    required:
    - accountId
    - serviceIdName
    properties:
      accountId:
        type: string
        description: The IBM Cloud account ID that owns the service ID.
      serviceIdName:
        type: string
        description: The name of the service ID being retired.
  steps:
  - stepId: findServiceId
    description: >-
      Resolve the service ID by name within the account. Matching on name rather
      than requiring the caller to supply an opaque id is what makes this runnable
      from a decommission ticket.
    operationId: listServiceIds
    parameters:
    - name: account_id
      in: query
      value: $inputs.accountId
    - name: name
      in: query
      value: $inputs.serviceIdName

      value: 1
    successCriteria:
    - condition: $statusCode == 200
    - context: $response.body
      condition: $.serviceids.length > 0
      type: jsonpath
    outputs:
      serviceIdId: $response.body#/serviceids/0/id
      serviceIdCrn: $response.body#/serviceids/0/crn
      locked: $response.body#/serviceids/0/locked
  - stepId: inventoryServiceKeys
    description: >-
      List the service ID API keys in the account so the credentials that deletion
      will destroy are recorded first. This API description exposes no way to
      filter keys by a service ID's own identifier, so the inventory is scoped to
      all service ID keys in the account and must be correlated by the reviewer.
    operationId: listApiKeys
    parameters:
    - name: account_id
      in: query
      value: $inputs.accountId
    - name: type
      in: query
      value: serviceid
    - name: scope

      value: account
    - name: pagesize
      in: query
      value: 100
    successCriteria:
    - condition: $statusCode == 200
    outputs:
      serviceKeys: $response.body#/apikeys
  - stepId: confirmDormant
    description: >-
      Read the service ID with its activity and history to establish when it last
      authenticated. A recent last_authn means something still depends on this
      identity and the decommission should stop here.
    operationId: getServiceId
    parameters:
    - name: id
      in: path
      value: $steps.findServiceId.outputs.serviceIdId
    - name: include_activity
      in: query
      value: true
    - name: include_history
      in: query
      value: true
    successCriteria:
    - condition: $statusCode == 200
    outputs:
      serviceIdName: $response.body#/name
      entityTag: $response.body#/entity_tag
      locked: $response.body#/locked
      history: $response.body#/history
      lastAuthentication: $response.body#/activity/last_authn
      authenticationCount: $response.body#/activity/authn_count
  - stepId: unlockServiceIdentity
    description: >-
      Unlock the service ID so it can be deleted. Identities provisioned for
      production are commonly locked at creation, and deletion is refused while the
      lock is in place.
    operationId: unlockServiceId
    parameters:
    - name: id
      in: path
      value: $steps.findServiceId.outputs.serviceIdId
    successCriteria:
    - condition: $statusCode == 200
  - stepId: deleteServiceIdentity
    description: >-
      Delete the service ID and every API key associated with it. This cannot be
      undone, and any access policy written against the identity should be
      withdrawn separately or it is left dangling.
    operationId: deleteServiceId
    parameters:
    - name: id
      in: path
      value: $steps.findServiceId.outputs.serviceIdId
    successCriteria:
    - condition: $statusCode == 204
  outputs:
    deletedServiceIdId: $steps.findServiceId.outputs.serviceIdId
    deletedServiceIdCrn: $steps.findServiceId.outputs.serviceIdCrn
    lastAuthentication: $steps.confirmDormant.outputs.lastAuthentication
