  description: >-
    OAuth2 client-credentials across all Efí hosts. Obtain a bearer token from
    the host's token endpoint using HTTP Basic auth with Client_Id and
    Client_Secret, then send it as `Authorization: Bearer`. Token endpoints
    differ per host: Pix `POST /oauth/token`
    (https://pix.api.efipay.com.br), Cobranças `POST /v1/authorize`
    (https://cobrancas.api.efipay.com.br), Open Finance `POST /v1/oauth/token`
    (https://openfinance.api.efipay.com.br). Access is scoped (cob.write,
    cob.read, pix.read, pix.send, webhook.write, gn.opb.payment.pix.send, etc).

- name: mutualTLS
  type: mutualTLS
  description: >-
    Mutual TLS (mTLS) client certificate is MANDATORY on every request to the
    Pix and Open Finance hosts, including the OAuth2 token request. Efí issues a
    `.p12` (PKCS#12) certificate in the account dashboard, which can be converted
    to `.pem`. This is a Brazilian Central Bank (BACEN) requirement for the Pix
    arrangement, not an Efí-specific choice. The Cobranças (Charges / Carnê) host
    does NOT require mTLS - OAuth2 alone is sufficient there. mTLS cannot be fully
    expressed as an OpenAPI 3.0 security scheme, so it is documented separately
    here and in prose within the OpenAPI description.
