  - `description` string, nullable
  - `status` 'active' | 'disabled'
  - `templateId` string

## Response `200`

Reaction updated

- Reaction: The fields a project monitor and a data reaction share. `Reaction` and `ProjectMonitor` each narrow `kind` and describe their own `spec`.
  - `id` string, uuid, required: Identifier of the monitor or reaction. This is the value the get, update and delete operations take.
  - `org_id` integer, required: Organization that owns the project
  - `app_id` integer, required: Project the monitor or reaction belongs to
  - `created_by` integer, nullable, required: User who created it, when it was created by a user credential
  - `name` string, required: Display name, unique case-insensitively among the project's live monitors and data reactions
  - `description` string, nullable, required
  - `kind` 'data', required: The reactions endpoints only ever return `data`.
  - `status` 'active' | 'disabled', required: Whether it is evaluating
  - `template_id` string, required: Template it was created from
  - `spec` object, required: Reaction parameters, normalized for the response: a reaction whose model transform is still held on `target` is returned with that transform copied into `spec.model`. Which properties are meaningful is decided by `template_id`. The create operation's request body lists the properties each template reads.
  - `target` union, required: A configured sink. An HTTP bearer token is never returned.
    - EmailSinkView
      - `type` 'email', required
      - `recipientUserIds` integer[]
      - `emails` string[]
    - HttpSinkView
      - `type` 'http', required
      - `url` union, required: The sink's URL. An empty string means the stored sink no longer passes validation. Update the sink to replace it.
        - string, uri
        - ''
      - `method` 'POST' | 'PUT' | 'PATCH'
    - SlackSinkView
      - `type` 'slack', required
      - `channelId` union, required: The Slack channel ID. An empty string means the stored sink no longer passes validation. Update the sink to replace it.
        - string
        - ''
      - `channelName` string
  - `targets` ReactionSinkView[], required: Every configured sink, ordered email, then slack, then http. `target` is the first of these. An HTTP sink's token is never returned.
    - union: A configured sink. An HTTP bearer token is never returned.
      - EmailSinkView
        - `type` 'email', required
        - `recipientUserIds` integer[]
        - `emails` string[]
      - HttpSinkView
        - `type` 'http', required
        - `url` union, required: The sink's URL. An empty string means the stored sink no longer passes validation. Update the sink to replace it.
          - string, uri
          - ''

          - string
          - ''
        - `channelName` string
  - `recipient_user_ids` integer[], required: Organization members emailed when it fires. Empty when there is no email sink, and for an email sink addressed only by `emails`. When a created email sink named no recipients at all, the API stores the creating user.
