note: SAP Ariba APIs use two-legged OAuth (client credentials / grant_type=openapi_2lo)
  with a per-application OAuth client ID plus Application Key, and access is granted
  per API through SAP Ariba approval rather than OAuth scopes; no scopes are documented
  (https://help.sap.com/docs/ariba-apis/help-for-sap-ariba-developer-portal/sap-ariba-developer-portal-authentication).
