  Partner-gated. The uShip developer portal is invitation-only ("You must have been invited to get access")
  and OAuth 2.0 credentials are issued by the uShip API team after a uShip Account Manager or General
  Manager approves API access. An API key can be self-served for the LTL products
  (https://developer.uship.com/about-our-apis/self-service-api-key--ltl-); keys are managed at
  https://developer.uship.com/apps/mykeys.

  description: >-
    uShip APIs use OAuth 2.0 (RFC 6749) for authentication and authorization. All four grant types are
    supported; the grant granted to an integration depends on its use case. Access tokens are presented on
    every subsequent call as `Authorization: Bearer {access_token}` (the "Bearer" label is case sensitive).
  flows:
  - flow: clientCredentials
    tokenUrl: https://api.uship.com/oauth/token
    tokenUrl_sandbox: https://apistaging.uship.com/oauth/token
    description: >-
      For applications that access endpoints as an anonymous user (for example searching listings).
      POST content-type application/x-www-form-urlencoded with
      grant_type=client_credentials&client_id=...&client_secret=...
    response_fields: [token_type, mapi, access_token, expires_in, refresh_token]

  - flow: authorizationCode
    tokenUrl: https://api.uship.com/oauth/token
    description: >-
      For web-based scenarios where the source code runs on a private server. Documented as the most secure
      grant type and the recommended default for server-side integrations.
  - flow: implicit
    description: >-
      For single-page JavaScript and browser/mobile applications that require less security; uShip
      recommends the authorization code grant instead where a more secure method is available.
  - flow: password
    description: >-
      Resource Owner Password Credentials — for authorizing an app that needs access to a uShip user
      account where the user supplies their own credentials.
  scopes: []
  scopes_note: >-
    uShip does not publish a named OAuth scope vocabulary. Access is granted per integration — "we grant
    access to the resources that make the most sense for your integration needs" — so authorization is
    resource-grant based rather than scope-string based. No scopes/ artifact is emitted.
- name: APIKey
  type: apiKey
  in: header
  description: >-
    A self-service API key is available for the LTL products; keys are created and rotated in the developer
    portal at https://developer.uship.com/apps/mykeys. The archived first-party Node.js wrapper initializes
    with an API key, API secret, uShip username, and password.
