    MemberPress is self-hosted. Credentials are issued by the MemberPress Developer Tools add-on
    inside the customer's own WordPress installation — there is no vendor-operated identity
    provider, no OAuth authorization server and no token exchange. MemberPress publishes two
    different header names for the same key across its own documentation surfaces; both are
    recorded below rather than picking one.
schemes:
- name: MemberPressApiKey
  type: apiKey
  in: header
  parameter: MEMBERPRESS-API-KEY
  description: >-
    Developer Tools API key. Generated automatically when the Developer Tools add-on is activated
    and regenerable from the MemberPress > Developer screen if compromised. This is the header
    name MemberPress documents on its own docs site.
  issuance: Self-service inside WP Admin (MemberPress > Developer). No vendor approval step.
  rotation: Regenerate from the Developer screen. MemberPress documents regeneration as the
    remedy for a compromised key; there is no published overlap/grace window.

- name: AuthorizationApiKey
  type: apiKey
  in: header
  parameter: Authorization
  description: >-
    The same Developer Tools API key sent in the `Authorization` header. This is the form used
    throughout the MemberPress REST API documentation repository and in every request of its
    published Postman collection. It is a BARE key, not an RFC 7235 `Bearer <token>` credential —
    an agent that prefixes `Bearer ` will fail.

- name: WordPressUserCapability
  type: session
  in: cookie
  parameter: wordpress_logged_in_*
  description: >-
    A logged-in WordPress user holding the `remove_users` capability (typically an administrator)
    is authorized without an API key. Callers lacking the capability receive HTTP 401.

webhook_authentication:
- name: MemberPressWebhookKey
  in: header
  parameter: memberpress-webhook-key
  direction: inbound-to-subscriber
  description: >-
    Webhook Key introduced in MemberPress 1.2.5. MemberPress sends this header on outbound webhook
    deliveries so the receiving endpoint can verify the call. This is a shared secret, not an HMAC
    signature over the payload — a receiver cannot verify body integrity, only origin possession
    of the key.

- name: BasicAuthentication
  in: header
  parameter: Authorization
  description: >-
    MemberPress additionally documents Basic Authentication (with the WordPress Application
    Passwords plugin) for webhook delivery, describing it in its own documentation as the "less
    secure" option.

gaps:
- No OAuth 2.0 or OpenID Connect surface — key-auth only, so there is no scope model and no
  scopes/ artifact for this provider.
- No published key-expiry, key-scoping or per-key permission model. A Developer Tools key is
  effectively administrator-equivalent over every MemberPress resource.
- Webhook deliveries carry a static shared secret rather than a per-payload signature.
- The `/me/permissions` endpoint that would let a caller discover its own authorization is
  documented by MemberPress as not present in all installations.
