note: >-
  Marin Software publishes no OpenAPI, so this profile is read from the provider's own
  live help-center API article rather than derived from a machine-readable spec. The
  dedicated developer portal that the docs point at
  (http://developers.marinsoftware.com/api/docs/) no longer resolves to a docs site —
  every *.marinsoftware.com subdomain is a wildcard catch-all that 301/200s to the
  marketing homepage — so the help center is the only remaining public auth reference.

  description: >-
    All Marin API endpoints require HTTP Basic authorization using a Marin username and
    password — the same credentials used to sign in to the MarinOne application, granting
    access to the same client accounts. Credentials are issued by a Marin representative;
    there is no self-service key issuance, no OAuth, and no API-key surface documented.

  note: >-
    Marin does not scope requests through the token. Account scoping is carried in required
    query-string parameters on every call, with the values read out of the MarinOne UI.

transport:
  https_only: true
  note: Only HTTPS requests are supported; plain HTTP will fail.
gaps:
- No OAuth 2.0 or OpenID Connect surface is documented.
- No scopes or permissions model is published, so scopes/ is intentionally absent.
- No API keys, no token rotation policy, and no MFA guidance for API credentials.
- Credentials are the interactive user's own username and password, so an API credential
  cannot be revoked independently of the human account.
