Zefr Authentication

generated: '2026-08-12'
method: probed
source: https://login.zefr.com/.well-known/openid-configuration
note: >-
  Zefr publishes no developer portal, no API reference and no OpenAPI, so there is no
  securityScheme block to derive from. What IS published, anonymously and machine-readably,
  is the OpenID Connect discovery document for Zefr's own identity provider — an Auth0
  tenant on the custom domain login.zefr.com (CNAME zefr-prod-cd-qq34zjzlcmyzcxao.edge.tenants.auth0.com)
  that authenticates the Zefr Brand Suitability Suite at suitability.zefr.com. This profile is
  read verbatim from that document. It describes how Zefr authenticates identities; it does NOT
  describe how a customer authenticates against the production API gateway at api.zefr.com,
  which Zefr does not document publicly.

provider: Auth0 (custom domain)
schemes:
- id: openIdConnect

  description: >-
    OpenID Connect 1.0 discovery is served anonymously. Authorization Code with PKCE
    (S256) is supported, as is the client_credentials grant — the grant a machine-to-machine
    API client would use.
- id: oauth2
  type: oauth2

api_key_auth:
  documented: false
  note: >-
    No public documentation describes an API key, bearer token or signing scheme for
    api.zefr.com. The gateway (Apigee) answers every anonymous request with a
    messaging.adaptors.http.flow.ApplicationNotFound fault, so no auth challenge is observable.
gaps:
- No public API reference documents how to authenticate against api.zefr.com.
- No audience/resource identifier is published for a Zefr product API.
- No scope reference page exists; only the standard OIDC identity scopes are advertised.
