  title: Google Forms Unsubscribe Form Watches
  summary: List the watches registered on a form and delete one to stop its notification delivery.
  description: >-
    The teardown half of the watch lifecycle. Watch ids are not something an
    integration usually holds onto, so removing a subscription starts by listing
    what the calling project actually has registered on the form, and then
    deleting the identified watch to stop delivery to its Pub/Sub topic. Worth
    running when decommissioning an integration or when a watch is failing
    delivery and should be replaced rather than renewed. Every step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.

  summary: Find and remove a form's registered watch to stop notifications.
  description: >-
    Lists the watches this project owns on the form, then deletes the first one
    returned so notification delivery stops.

  steps:
  - stepId: listRegisteredWatches
    description: >-
      List the watches this project owns on the form. This is the only way to
      recover a watch id that was not persisted at creation time, and it also
      surfaces each watch's state and error type so a failing subscription can be
      told apart from a healthy one.
    operationId: listWatches
    parameters:
    - name: formId
      in: path
      value: $inputs.formId
    successCriteria:
    - condition: $statusCode == 200
    - context: $response.body
      condition: $.watches.length > 0
      type: jsonpath
    outputs:
      watches: $response.body#/watches
      watchId: $response.body#/watches/0/id
      state: $response.body#/watches/0/state
      errorType: $response.body#/watches/0/errorType
  - stepId: deleteWatch
    description: >-
      Delete the identified watch. Delivery to its Pub/Sub topic stops
      immediately; the topic itself is untouched and has to be cleaned up
      separately if it is no longer needed.
