scoping:
  unit: questionnaire
  detail: >-
    A key is bound to exactly one questionnaire. It is validated against the questionnaire
    named by `project_uuid` in the participant request body, or by `questionnaire_id` in
    the API-key management path. Cross-questionnaire use returns 403 "API Key not
    associated with this Questionnaire".
scopes:
- {scope: 'participant:write', allows: Create participants; update participant outcome,
  in_spec_enum: true}
- {scope: 'participant:read', allows: Read participant data, in_spec_enum: false, note: documented
    on the portal but not enumerated in ApiKeyCreateRequest, and no read operation exists
    in the published contract}
- {scope: 'participant:delete', allows: Delete participants, in_spec_enum: false, note: documented
    on the portal but not enumerated in ApiKeyCreateRequest, and no delete-participant
    operation exists in the published contract}
- {scope: 'apikey:write', allows: Create new API keys for the same questionnaire, in_spec_enum: true}
- {scope: 'apikey:delete', allows: Delete API keys for the same questionnaire, in_spec_enum: true}
scopes_note: >-
  These are API-key permissions, not OAuth scopes — there is no oauth2 securityScheme on
  the Integration API, so no scopes/ artifact is emitted. Two portal-documented scopes
  (participant:read, participant:delete) have no corresponding operation in the published
  OpenAPI, which means either the contract is incomplete or those scopes govern an
  unpublished surface.
key_lifecycle:
  bootstrap: >-
    The first key for a questionnaire must be created in the Clearspeed web app by a
    questionnaire or tenant Admin (Integration page -> API Keys -> + Generate New).
    Subsequent keys can be minted via createApiKey with the apikey:write scope.
  visibility: >-
    The full api_key value is returned only in the 201 response to createApiKey. There is
    no list or read operation, so an unrecorded key value is unrecoverable — and delete
    addresses the key by its raw value, so losing it also loses the ability to revoke it
    through the API.
  rotation: >-
    Documented zero-downtime rotation: create a replacement with the same scopes, switch
    the integration, verify, then delete the old key.
  revocation: Immediate. A deleted key returns 401 on the next request.
  expiry: none documented
  format: >-
    Not specified in the docs. The OpenAPI create example shows a cs_live_ prefixed
    placeholder; the delete example uses a bare 64-character hex value. The prefix is
    therefore not guaranteed.
outbound_authentication:
  context: Clearspeed calling the customer's webhook endpoint
  methods:
  - {method: api-key, detail: 'Clearspeed sends a customer-supplied key value as a header
      on every delivery'}
  - {method: oauth2-client-credentials, detail: 'Clearspeed performs the client credentials
      flow against a customer-supplied Token URL (Audience, Client ID, Client Secret)
      before each delivery and sends an Authorization Bearer token'}
  signature_verification: none
  docs: https://developer.clearspeed.com/webhooks
  note: >-
    This is Clearspeed acting as an OAuth CLIENT against the customer. It is not
    authentication to the Clearspeed API and does not make the Integration API an OAuth API.
other_auth_surfaces:
- surface: developer portal MCP server
  url: https://developer.clearspeed.com/mcp
  scheme: OAuth 2.1 bearer (RFC 9728 protected resource)
  issuer: https://auth.cloud.redocly.com
  note: >-
    Redocly Reunite portal identity protecting the documentation MCP server. Unrelated to
    Integration API authentication. See mcp/clearspeed-mcp.yml.
gaps:
- No IP allowlisting documented.
- No mTLS option.
- No key expiry or last-used telemetry.
- No list-keys operation, so key inventory must be maintained client-side.
- No rate limits tied to a key.
