summary: >-
  Ramp Network has no OAuth surface and no bearer-token API. The public Host API is
  largely ANONYMOUS — assets, prices, currencies, payment methods and payout methods
  are readable with no credential at all (verified live on 2026-08-26 against
  https://api.rampnetwork.com/api/host-api/v3/currencies, HTTP 200). Three distinct
  credential mechanisms exist on top of that, and they are not interchangeable.
schemes:
  - id: hostApiKey
    type: apiKey
    in: query
    name: hostApiKey
    required: conditional
    applies_to:
      - GET /host-api/v3/assets
      - GET /host-api/v3/offramp/assets
      - POST /host-api/v3/onramp/quote/all
      - POST /host-api/v3/offramp/quote/all
      - Ramp Instant SDK / widget initialisation
      - Hosted widget URL (https://app.rampnetwork.com/?hostApiKey=...)
    description: >-
      The integration (partner) key. Issued by Ramp Network on request — there is no
      self-service key issuance. On the assets endpoints it is optional and unlocks
      an `enabledFeatures` list plus partner-specific configuration; on the quote
      endpoints the docs present it as the required identifier. It is also the key
      that attributes purchases to a partner integration for revenue share. Because
      it travels in the QUERY STRING and is embedded in client-side widget
      initialisation, it is a partner identifier rather than a secret.

  - id: purchaseViewToken
    type: apiKey
    in: query
    name: secret
    required: true
    applies_to:
      - GET /host-api/purchase/{id}
      - GET /host-api/offramp/sale/{id}
    description: >-
      A per-transaction capability token (`purchaseViewToken` / `saleViewToken`)
      delivered with the PURCHASE_CREATED / OFFRAMP_SALE_CREATED SDK event and the
      corresponding webhook. It is passed as the `secret` query parameter and scopes
      read access to exactly one transaction. This is an object-capability model,
      not an account credential — possession of the token is the authorisation.
  - id: webhook-signature
    type: signature
    direction: inbound-to-integrator
    header: X-Body-Signature
    algorithm: ECDSA over secp256k1 with SHA-256, DER signature, base64 encoded
    canonicalisation: >-
      JSON request body serialised with fast-json-stable-stringify (object keys
      sorted alphabetically, no whitespace)
    key_distribution: public keys published verbatim in the webhook documentation (separate production and demo keys)
    description: >-
      Ramp Network signs every outbound webhook call so the integrator can verify
      authenticity. This is the only cryptographic authentication in the surface,
      and it authenticates RAMP TO THE INTEGRATOR, not the other way round.

gaps:
  - >-
    No OAuth 2.0, no OpenID Connect, no scope model — so scopes/ is intentionally
    not emitted for this provider.
  - >-
    hostApiKey is transmitted as a URL query parameter and is present in
    client-side widget configuration, so it will appear in browser history, proxy
    logs and referrer headers. The docs do not describe rotation or revocation.
  - >-
    No published authentication error catalogue; failures surface through the
    generic `{ code, statusCode }` error envelope.
