O cliente já confia na entidade que gerou o certificado TLS (nesse caso, o Let's Encrypt, mas veremos sobre isso mais tarde), então ele pode verificar que o certificado é válido.

Então, utilizando o certificado, o cliente e o Proxy de Terminação TLS decidem como encriptar o resto da comunicação TCP. Isso completa a parte do Handshake TLS.

### Response

If the token is valid and access is approved, the plugin must return a `200` (OK) HTTP status code.

A `200 OK` Response should have `application/json` content-type and body with the following structure:

```json
