  title: SharePoint Verify Site Connection and Identity
  summary: Escalate from a cheap reachability probe to identity, site detail, and visible lists.
  description: >-
    The first thing any SharePoint integration should run after wiring up Azure
    AD OAuth. The workflow escalates deliberately: a near-free title read proves
    the site URL and token are usable at all, the profile read proves which
    identity the token actually carries, the full web read resolves the site's
    id and server-relative URL for later steps, and the list enumeration reveals
    what the granted scopes can genuinely see. Failing early here is far cheaper
    than failing halfway through a write. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.

  summary: Confirm the SharePoint site is reachable, the token is valid, and lists are visible.
  description: >-
    Probes the site title, resolves the calling user's profile, reads the full
    site properties, and enumerates the lists the caller is permitted to see.

        default: 50
  steps:
  - stepId: probeSite
    description: >-
      Cheapest possible reachability check. A 200 here proves the site URL
      resolves and the bearer token is accepted before anything heavier runs.
    operationId: getWebTitle
    successCriteria:
    - condition: $statusCode == 200
    outputs:
      siteTitle: $response.body#/value
  - stepId: whoAmI
    description: >-
      Resolve the identity behind the token. Confirms the integration is acting
      as the account you expect rather than a stale or over-scoped principal.
    operationId: getMyUserProfile
    successCriteria:
    - condition: $statusCode == 200
    outputs:
      accountName: $response.body#/AccountName
      displayName: $response.body#/DisplayName
      email: $response.body#/Email
      department: $response.body#/Department
  - stepId: readSite
    description: >-
      Read the full site (web) properties, capturing the site id and the
      server-relative URL that folder and file operations depend on later.
    operationId: getWeb
    parameters:
    - name: "$select"
      in: query
      value: Id,Title,Url,Description,ServerRelativeUrl,Created,LastItemModifiedDate
    successCriteria:
    - condition: $statusCode == 200
    outputs:
      siteId: $response.body#/Id
      siteUrl: $response.body#/Url
      serverRelativeUrl: $response.body#/ServerRelativeUrl
      lastItemModifiedDate: $response.body#/LastItemModifiedDate
  - stepId: enumerateLists
    description: >-
      Enumerate the non-hidden lists and libraries the caller can see. An empty
      result with a 200 usually means the token's scopes are narrower than
      intended rather than that the site is empty.
    operationId: getLists
    parameters:
    - name: "$select"
      in: query
      value: Id,Title,BaseTemplate,ItemCount,Hidden
    - name: "$filter"
      in: query
      value: Hidden eq false
    - name: "$top"
      in: query
      value: $inputs.listPageSize
    successCriteria:
    - condition: $statusCode == 200
    outputs:
      lists: $response.body#/value
      firstListTitle: $response.body#/value/0/Title
  outputs:
    siteTitle: $steps.probeSite.outputs.siteTitle
    siteId: $steps.readSite.outputs.siteId
    serverRelativeUrl: $steps.readSite.outputs.serverRelativeUrl
