summary:

  - header
  oauth2: false
  openid_connect: false
  mutual_tls: false
  scopes: false
  note: >-
    Two different Authorization header schemes are in play and the specs do not make that obvious. A
    caller first signs a JWT with an RSA private key and sends `Authorization: JWT <jwt>` to the Auth API;
    the Auth API returns an opaque bearer token, which is then sent as `Authorization: Token <token>` to
    the Data API and Metadata API. The Engine API is different again — it is unauthenticated at the
    transport level and identifies the caller by the retailer shortname in the path plus the account
    fields in the request body.
schemes:
- name: JWTAuthentication
  api: Monetate Auth API
  type: apiKey
  in: header
  parameter: Authorization
  value_format: JWT <signed_jwt>
  description: >-
    A signed JSON Web Token proves possession of a private key whose public half was uploaded in the
    Monetate platform (Settings > Sites > API Keys tab). The JWT payload must carry an `iat` claim (Unix
    timestamp of the request; 60 seconds of clock skew allowed) and a `username` claim matching the API
    username generated on that API Keys tab.
  algorithms:
  - RS256
  - RS384
  - RS512
  credential_provisioning: >-
    Self-service inside the Monetate platform UI — generate an API key/username on the API Keys tab of the
    Sites page under Settings, and upload the matching RSA public key. Requires an existing Monetate
    account; there is no public signup.
  revocation: Deactivate the public key in the UI; every token issued against it stops working (403).

- name: TokenAuthentication
  api: Monetate Metadata API
  type: apiKey
  in: header
  parameter: Authorization
  value_format: Token <token_string>
  description: >-
    Opaque bearer token obtained from GET /api/auth/v0/refresh/. Sent on every Metadata API request.
  source: openapi/monetate-metadata-api-openapi.yml
- name: Token Authentication
  api: Monetate Data API
  type: apiKey
  in: header
  parameter: Authorization
  value_format: Token <token_string>
  description: >-
    Same opaque bearer token as the Metadata API. Note the securityScheme key in the Data API spec
    contains a space ("Token Authentication") while the Metadata API spec uses "TokenAuthentication" —
    the same mechanism named two ways across two published specs.

token_flow:
  step_1:
    request: GET https://api.monetate.net/api/auth/v0/refresh/?ttl=3600
    headers:
      Authorization: JWT <signed_jwt>
    query:
      ttl:
        description: Requested token lifetime in seconds.
        default: 3600
        minimum: 600
        maximum: 43200
  step_2:
    response_body_path: data.token
    also_returns:
    - data.expires_in
    - data.expires_at
    note: >-
      `expires_in` always equals the requested `ttl`; `expires_at` is seconds since epoch, so a client can
      pre-emptively refresh rather than waiting for a 401.
  step_3:
    request: Any Data API or Metadata API call
    headers:
      Authorization: Token <token_string>
unauthenticated_surfaces:
- api: Monetate Engine API
  endpoint: POST https://engine.monetate.net/api/engine/v1/decide/{retailerShortname}
  note: >-
    The published Swagger 2.0 document declares no securityDefinitions and no security requirement. The
    caller is identified by the retailer shortname path parameter and the channel/instance/domain values
    in the request body. This is deliberate — the endpoint is designed to be called from a browser or a
    mobile app where no secret can be held — but it means the Engine API's access model is not described
    in machine-readable form anywhere.
gaps:
- >-
  The Auth API spec declares JWTAuthentication as `type: apiKey` rather than `type: http, scheme: bearer,
  bearerFormat: JWT`, so tooling cannot tell it is a JWT from the spec alone.
- No `security` block is applied per-operation in the Engine API spec.
- No OAuth 2.0, no OpenID Connect, no scopes anywhere in the product APIs. (The only OAuth surface Monetate
  publishes is on the WordPress marketing site's MCP server — see mcp/monetate-mcp.yml.)
